As the bushfires continue in northern New South Wales the Rural Fire Service warns "fires will not be contained in time and will threaten lives and properties"




NSW Rural Fire Service:

Large areas of the state are also forecast to experience Severe and Extreme fire danger. This includes in the north coast and northern NSW areas, where there is a large number of fires already burning. These fires will not be contained in time and will threaten lives and properties.

Based on latest forecasts from the Bureau of Meteorology, the following fire danger ratings are expected on Tuesday. These are subject to change as forecasts are updated:



  • Catastrophic – Greater Sydney, Greater Hunter (including the Blue Mountains and Central Coast areas) and Illawarra/Shoalhaven
  • Extreme – North Coast, Central Ranges, Northern Slopes and North Western 
  • Severe – Far North Coast, New England, Far South Coast, Southern Ranges, Lower Central West Plains......
An overview of the areas likely to be impacted is available here. Check our Major Fire Updates page for updates on affected areas.

A statewide total fire ban has been declared for all areas of NSW for all 
of Tuesday 12 November 2019.

BACKGROUND

MSN News, 11 November 2019:

In the past I’ve have heard some federal politicians dodge the question of the influence of climate change on extreme weather and fires by saying, “It’s terrible that this matter is being raised while the fires are still burning.” But if not now, then when?

“Unprecedented” is a word that we are hearing a lot: from fire chiefs, politicians, and the weather bureau. I have just returned from California where I spoke to fire chiefs still battling unseasonal fires. The same word, “unprecedented”, came up.

Unprecedented dryness; reductions in long-term rainfall; low humidity; high temperatures; wind velocities; fire danger indices; fire spread and ferocity; instances of pyro-convective fires (fire storms – making their own weather); early starts and late finishes to bushfire seasons. An established long-term trend driven by a warming, drying climate. The numbers don’t lie, and the science is clear.

If anyone tells you, “This is part of a normal cycle” or “We’ve had fires like this before”, smile politely and walk away, because they don’t know what they’re talking about.

In NSW, our worst fire years were almost always during an El Nino event, and major property losses generally occurred from late November to February. Based on more than a century of weather observations our official fire danger season is legislated from October 1 to March 31. During the 2000s though, major fires have regularly started in August and September, and sometimes go through to April.

The October 2013 fires that destroyed more than 200 homes were the earliest large-loss fires in NSW history – again, not during an El Nino.

This year, by the beginning of November, we had already lost about as many homes as during the disastrous 2001-2002 bushfire season. We’ve now eclipsed 1994 fire losses.

Fires are burning in places and at intensities never before experienced – rainforests in northern NSW, tropical Queensland, and the formerly wet old-growth forests in Tasmania.

On Friday, the NSW Rural Fire Service sent out an alert that fires were creating thunderstorms – pyro-convective events. In my 47 years of fighting fires I don’t remember this happening much. Now it happens quite regularly. On Friday, the atmosphere was relatively stable and therefore shouldn’t have been conducive to these wildly unpredictable and dangerous events. Yet it happened. Unprecedented.

The drought we are facing is more intense than the Millennium Drought, with higher levels of evaporation due to higher temperatures. This has dried out the bush and made it easier for fires to start, easier for them to spread quickly, and as we saw on Friday, enabling spot fires to start twice as far ahead of the main fires as we would normally expect.

Warmer, drier conditions with higher fire danger are preventing agencies from conducting as much hazard reduction burning – it is often either too wet, or too dry and windy to burn safely. Blaming "greenies" for stopping these important measures is a familiar, populist, but basically untrue claim.

Together with 22 other retired fire and emergency service chiefs, I spoke out earlier this year. We felt we had a duty to tell people how climate change is super-charging our natural disaster risks. I wish we were wrong, but we’re not.

The Daily Examiner, 11 November 2019:

Multiple homes in and around Nymboida have been destroyed after a fire storm swept through the area on Friday night. 

The Liberation Trail fire was one of at least 14 out of control blazes simultaneously at Emergency Warning status during in was described by NSW Rural Fire Service as an unprecedented level of fire activity. 

Residents were evacuated over to locations at Grafton including Headspace and Hawthorne Park. The Armidale Rd remains closed at Coutts Crossing and many are yet to return to find out the full extent of damage to their properties. 

However, one Nymboida resident did stay to successfully protect his home from devastation. 

As fire fighting resources were depleted, so too were those of the national media, with the Clarence Valley largely off the radar as networks concentrated on fires further south. But one crew did manage to reach Nymboida resident Peter Simpson. 

Mr Simpson’s actions coupled with a solid fire plan almost certainly saved his home. 

While resources were stretched with every available RFS vehicle on the ground assisting with the fires, the breadth of fires meant crews simply couldn’t be in every danger zone. 

“It was like an inferno, it was like the apocalypse, it was like hell on earth,” Mr Simpson told Channel 7 reporters. 

“I hosed and hosed and hosed, drained my dams, and I just hung here for the whole night. I’m glad I put my buffer in and had a fire plan. 

“It’s carnage. Every second house on this road’s gone, the whole of Fricker Road’s gone, village gone, and surrounding houses, most of Nymboida is going to be displaced because they have nowhere to live. 

“I’m just glad that I’m safe, and I’m really sorry for every person in this whole area that’s lost out. My heart bleeds for them. 

“I can’t believe there was no help. There were no water bombers.” 

At Tallawudjah Creek near Glenreagh, RFS aerial support helped to save Renay Hayes’ property. 

Ms Hayes said the past few days had been the most terrifying of her life and she thanked some “legends” in the sky. 

“The fire got really close,” she said. “There were flames we could see coming over the mountain at us,” Ms Hayes said. “It was so scary.” 

“We didn’t have warning really. We knew it was there, but it was a matter of 20 minutes between us being in the safe zone and the flames coming at us.” 

Ms Hayes said the sounds of helicopters made her even more petrified, but as the fire got closer, those same helicopters attacked the fire and saved her property. 

“The chopper was doing 1 minute 43 seconds from pick up to dump,” she said. 

“It was terrifying, and we were pretty sure our house was gone, but that legend or legends in that chopper saved us. 

“Whoever was in that craft saved my house, and I cannot thank them enough.” 

Ms Hayes walked her horses 3km to safety. 

“We are still on evacuation list, but unless the wind comes back we are okay,” she said on Saturday night. “There were friends who lost their houses, but I’m not certain how many are gone. I know two for certain, it’s still mighty orange here.” 

“I’ve been here for 32 years and never seen it like this.”

The Daily Examiner, 11 November 2019, p.5:
A collapsed bridge has restricted access to properties in the Kangaroo Creek area as residents return to assess the damage from bushfires.
The bridge located 18km along Kangaroo Creek Rd collapsed after being damaged by fires in the out of control Liberation Trail bush fire, which has now burnt more than 113,100 hectares of land.
Grafton real estate agent Adam Crawley took the photo on Saturday while going to check on a friend’s place who is currently in India.
“I wasn’t out there last night (Friday) and I’m glad I wasn’t it looks pretty hairy,” Mr Crawley said.
“(There’s) no burnt houses that I saw but everything else is burned. All the way up to people’s sheds, water tanks and cars.”
The road to Nymboida is closed at the Kangaroo Creek Road turnoff, and authorities are urging any non-essential travel to be postponed to alleviate congestion in fire hotspots.
A 50km stretch of the Armidale Rd between Coutts Crossing and Clouds Creek which includes Nymboida is closed in both directions.
Motorists are advised to avoid the area.
The Daily Examiner, 11 November 2019, p.3:

A woman was killed trying to protect her home from a bush fire near Glen Innes.
Vivian Chaplain was at her property at Wytaliba on the upper reaches of the Mann River on Friday night when flames tore through the town.
She was found near her shed unconscious and suffering burns to at least 40 per cent of her body.
Tasmanian fire fighters, deployed to NSW to help with the bushfire emergency, performed CPR and first aid on the victim for "several hours".
She was eventually flown to Concord Hospital and died overnight.
The Coffs Coast Advocate, 11 November 2019:

RESIDENTS in the Orara Valley are being advised to consider leaving their properties tonight as a catastrophic 24-hours looms, in what potentially could end as one of the worst days for bushfire destruction in NSW's history.  
This morning the Rural Fire Service has staged an emergency briefing at its fire control centre in Coffs Harbour. 
Information on dangerous fire and conditions has been circulated for residents in the Nana Glen, Lowanna, Ulong, Megan/Cascade, Coramba, Karangi, Orara, Bucca and greater Coffs Harbour areas....
The Rural Fire Service's Greater Coffs Harbour Fire Prediction Map released this morning.

, 10 November 2019:
Wytaliba is "burning like a BBQ" after a devastating bushfire descended on the northern NSW town, claiming the lives of two people.
On Sunday afternoon the out-of-control fire, which has burnt through more than 12,450 hectares, was rated at watch and act.
It has been reported the second victim of Friday's firestorm, who was found in a burnt car near Glen Innes, is George Nole.
Those who knew Mr Nole, an elderly man from Wytaliba, took to Facebook to pay tribute to him.
"He was such a gentlemen. Will be missed by many," Crystal Grob posted.
RFS member Peter Chaffey, who has command of Wytaliba area, said it was likely the community wouldn't be allowed down the steep, winding, 12-kilometre road to the town, until Monday morning.
"The whole hill has been impacted by fire and every time we go down there, we have to clear the road," he told AAP.
"It is a crime scene down there and we have to let the police do their thing."
Mr Chaffey said a press photographer in the town early on Sunday morning focused on the car Mr Nole died in - an act that had "stirred up the community to no end".
"We've got a really sensitive community," he said.
"I know the world wants to see the pictures.
"But I was speaking to a woman who said 'I haven't been able to get in there, I had dogs chained up and other pets. I know they're deceased.'
"She needs to go in and deal with that - not see it (first) on the news."

NOTE:
In NSW Berejiklian Coalition Government's 2019-20 Budget, Rural Fire Service funding was $26.7 million less than in 2018-19 with capital expenditure funding $49.9 million less.

The scale of NSW bushfires is beginning to emerge in November 2019



The New South Wales Northern Rivers region has been experiencing widespread  bushfires since September 2019. According to the NSW Rural Fire Service est. 1,055,168 hectares were on fire on 8-9 November - that's over 2,607,376 acres.

On 9-10 November est. 195,347 hectares on the Mid-North Coast were alight - that's another 482,713 acres.

Elsewhere, between 8-10 November the Tenterfield area had 48,991 hectares burning and another 29 local government areas were also battling bushfires.

Today 41 NSW local government areas officially have a High fire danger rating and another 26 have a Very High fire danger rating, with no rain forecast except for 1mm between Albury and the coast on the NSW-Vic border.

As of 12.30am there were 74 bush fires still burning across the state, 43 are still not under control, 1 fire remains at Emergency Warning and 15 are at Watch and Act.

The end is not yet in sight.

Two lives lost and 88 homes destroyed across northern NSW to date in 2019 bushfire season


Bushland and grass fires are still burning across the Northern Rivers region and NSW predominately volunteer 'firies' are still keeping the flames from our doors where and when they can.

Here is the sad toll......

NSW Rural Fire Service, media release, 16 October 2019:
The NSW Rural Fire Service (NSW RFS) has confirmed 64 homes were destroyed in last week’s bush fires across northern NSW.
NSW RFS Building Impact Assessment Teams have now completed the bulk of inspections of fire affected areas.
Over the past week, these teams have conducted more than 1000 surveys of homes, buildings and facilities in the area directly impacted by fires.
The assessments have found:
›   64 homes destroyed, 23 damaged
›   7 facilities destroyed, 9 damaged
›   153 outbuildings destroyed, 70 damaged
›   329 homes in the direct area impacted by the fire saved
Of those homes destroyed, 44 were at the Busbys Flat fire.
Nineteen were due to the Long Gully Road fire, and in addition to 24 which were destroyed by the same fire in September. Tragically, two lives were also lost in this fire last week.
One home was destroyed at the Purgatory Creek fire near the Gwydir Highway at Jackadgery last week.
Commissioner Shane Fitzsimmons said so far this season, there has been more than 5000 bush and grass fires across NSW, which have burnt through more than a million hectares of land.
“We have seen large and destructive fires take an enormous toll on lives, farms, businesses, homes and communities in recent weeks and months, with a loss of 108 homes already this season.
“And while each one of the properties destroyed is a tragedy for those impacted, more than 1200 homes in the direct area of these fires have been saved due to the hard work of firefighters, landholders and residents.
“It’s important to remember that this is no ordinary bush fire season and we can’t afford to have anyone think this is just another year.
“The crippling effects of the drought, unseasonably warm weather and strong winds have seen fires develop quickly and impacted on lives, farms, businesses, homes and communities.
“There will be more fires this season and there’s a high likelihood of more homes being destroyed – so now is the time to get ready, make a plan, and have a conversation with your family.”

Bushfire forces temporary part closure of Yuraygir National Park in the Clarence Valley


Department of Planning, Industry and Environment & NSW National Parks and Wildlife Service, media release, 18 September 2019: 

Bushfire forces temporary part closure of Yuraygir National Park

Following last week's destructive bushfires part of the Yuraygir National Park, including a section of the iconic Yuraygir Coastal Walk are temporarily closed. 

A National Parks and Wildlife Services spokesperson said 6600 hectares of private property and 4000 hectares of Yuraygir National Park burned in the Shark Creek 2 fire. 

"The walking track from Mara Creek Picnic Area, just south of Angourie to Lake Arragan is closed while the site is being managed," the spokesperson said. 

"Mara Creek Picnic Area and Shelley Headland Camping Areas are also closed. 

"The rest of the Yuraygir Coastal Walk, from Lake Arragan to Red Rock remains open. 

"Angourie Bay Picnic Area and all other visitor areas within Yuraygir National Park are still accessible to the public." 

"Unfortunately, the fire damage extended to the toilets, a bridge, numerous elevated walkways, signs, picnic tables, seating, fencing, bollards, staircases and drainage structures across the park," the spokesperson said. 

"NPWS will continue to assess the damage and address safety hazards including burnt structures and trees as a priority. 

"We're urging the public to put safety first and to be patient until works to repair damage commence. 

"The damage is significant and will take some time to restore. 

"In the meantime, we're investigating temporary solutions to allow the public access to the park. 

We will keep everyone informed of these decisions once they are made."

"We'd like to acknowledge the work of the NPWS and RFS (Rural Fire Service) crews who worked tirelessly with significant support from dozers and aircraft to contain the fire."

Campfires and barbecues using wood, charcoal or other solid fuels have been banned in all NSW state forests from 1 September 2019 until further notice


Forestry Corporation of NSW, media release, 30 August 2019: 

Campfires and barbecues using wood, charcoal or other solid fuels have been banned in all State forests on the North Coast, Northern Tablelands Central West Tablelands, South Coast and parts of Western NSW from Sunday 1 September until further notice to reduce the risk of bushfires.

Forestry Corporation of NSW's Senior Manager of Stewardship, Kathy Lyons said the ban applied in all State forests from the Central Coast to the Queensland border, from Nowra to the Victorian border, on the Central West tablelands and north of the Mitchell Highway, and visitors should plan to bring gas stoves for cooking. 

“Fire season has commenced early this year due to extremely dry conditions across much of the state. Our firefighters on the north coast are already fully committed fighting many fires which have taken off due to the dry conditions,” Ms Lyons said. 

“In the past few weeks our firefighters have been tackling wildfires around Grafton and Wauchope and with the weather forecast predicting hotter and drier weather and little rain on the horizon, we need to take steps now to minimise the risk of further bushfires. 

“All fires using solid fuels such as wood or charcoal are now banned in most State forests across the state until further notice. 

“Campers and picnickers wishing to light a fire to cook in these forests can only use gas appliances until the ban is lifted, which won’t be until after significant rainfall. 

“This ban applies every day, not just on days when total fire bans are declared, so we are asking people who are planning to camp in the forests during spring and summer to plan ahead and bring gas appliances. 

“Visitors should also be prepared for days when total fire bans are declared, as all fires including gas fires are prohibited on total fire ban days. 

Information on total fire bans is available on the Rural Fire Service website.

“State forests are popular with campers and visitors throughout the spring and summer period and while we encourage people to get out into our forests and enjoy them, we do need to act to reduce the bushfire risk during the high fire danger period. 

“Solid fuel fire bans improve safety for campers and local communities.” 

Failure to comply with the Solid Fuel Fire Ban carries a maximum penalty of $2200. If in doubt, contact your local forestry office.

Recent bushfires in Clarence Valley causing high air pollution


As of yesterday there were still sixteen fires burning across the Clarence Valley, according to the NSW Rural Fire Service. 

The Daily Examiner, 13 August 2019, p.5: 

 People with heart and respiratory conditions are being urged by the North Coast Public Health Unit to be careful as recent bush fires are causing high pollution.

Communities around Grafton may be particularly affected in the coming days, and Public Health North Coast assistant director Greg Bell said children, older adults and people with heart and lung conditions are most susceptible to air pollution and excessive smoke. 

“If you have asthma you should follow your Asthma Action Plan and take your relieving medication where necessary and if symptoms get worse, seek medical advice,” MrBell said.

The Fire Next Time: "Climate is a driver of wildfire and of fire full stop"



Image: Green Cross Australia

ABC News, 1 December 2018:

Both the bushfires and the heatwave ravaging parts of Queensland have been described as extraordinary and abnormal.

Bureau of Meteorology Queensland manager Bruce Gunn said records had tumbled in a week of widespread and protracted heatwave conditions, combined with catastrophic fire danger.

"On Wednesday, Rockhampton Airport recorded catastrophic [fire] conditions for approximately three-and-a-half hours," Mr Gunn said.

"This was the first time this district has recorded catastrophic conditions and the most prolonged event in Queensland since the implementation of the current Fire Danger Rating System in 2010."

Fire ecologist Philip Stewart said Queensland's fires of the past few days were historically unusual.

"When one looks at the charcoal records with Aboriginal burning, we haven't seen any indicators that show that there had been mass fires or large intense fires like we are seeing today, or 'mega-fires', as I would call them," Dr Stewart said.

"They're not something one would expect at this time, but then again, fires of this nature can occur anywhere, provided that there's the right climatic conditions and the right fuels and so on."

Dr Stewart said the intensity and the extent of the fires was abnormal, as was the time of year that they were occurring.

He said they were "absolutely" a result of climate change.

"Climate is a driver of wildfire and of fire full stop," Dr Stewart said.

"So when we start to see an increase in temperature, we start see an increase in energy availability in that atmosphere, and that obviously will increase the potential for high-intensity fires and fast fires as well."…..

"We have definitely seen over the past 10 to 15 years an earlier onset of burning and a later fire season as well," Dr Stewart said.

He said the fire seasons were starting to overlap, within Australia and globally, so sharing resources would become harder.

And the tropics burning this week demonstrated that even areas traditionally considered safe were at risk.

"I would say that wherever you are you should have a fire plan … even [in] urban areas as we've seen in Greece recently, right down to the coast, and in the Californian fires … there's always a possibility that a fire can get in unless it's a concrete jungle," he said……

Bushfire and Natural Hazards Cooperative Research Centre (CRC) CEO Richard Thornton said past fires were not necessarily predictive of future bushfires, so people needed to consider the worst-case scenario for them.

"It's about forward planning and getting people to recognise the changing nature of risk," Dr Thornton said.

"I think what we can say more generally and this doesn't apply just to Queensland … is in the Australian context, if we have days that are in the 40s with very high winds and very low humidity, the chances of fire starting and becoming uncontrollable very quickly, is highly likely.

"On those days, communities need to be very vigilant and aware of the environment and what their plans are for those days, and whether it's going to be to leave early," he said.

Dr Stewart said he would like to see an increase in funding for fire management and crews.

"There is very little funding available for any proactive fire management and fire mitigation research.

"We need a lot more, especially in Queensland," Dr Stewart said.

If you live in a NSW rural/regional area or an outer metropolitan suburb with thick tree cover.....


Now is the time to make or update your bushfire survival plan.

Because the fires have come early this year and intermittant rainfall is unlikely to ease the threat for long.

Crikey.com.au, 16 August 2018:

NSW has declared its earliest total fire ban on record, with hundreds of South Coast residents forced to flee their homes amidst a massive blaze.

The Sydney Morning Herald reports that fire crews battled at least 83 fires across the state, following stronger-than-expected winds, creating fire bans that beat the previous record by two weeks. Compounding problems was the fact that, according to The Daily Telegraph ($), two huge water bombers were not in action because they had not yet arrived from the US ahead of Australia’s summer season.

Global fires affect Earth's methane emission levels


National Aeronautics and Space Administration (NASA), 4 January 2018:


A reduction in global burned area in the 2000s had an unexpectedly large impact on methane emissions.

A new NASA-led study has solved a puzzle involving the recent rise in atmospheric methane, a potent greenhouse gas, with a new calculation of emissions from global fires. The new study resolves what looked like irreconcilable differences in explanations for the increase.

Methane emissions have been rising sharply since 2006. Different research teams have produced viable estimates for two known sources of the increase: emissions from the oil and gas industry, and microbial production in wet tropical environments like marshes and rice paddies. But when these estimates were added to estimates of other sources, the sum was considerably more than the observed increase. In fact, each new estimate was large enough to explain the whole increase by itself.

Scientist John Worden of NASA's Jet Propulsion Laboratory in Pasadena, California, and colleagues focused on fires because they're also changing globally. The area burned each year decreased about 12 percent between the early 2000s and the more recent period of 2007 to 2014, according to a new study using observations by NASA's Moderate Resolution Imaging Spectrometer satellite instrument. The logical assumption would be that methane emissions from fires have decreased by about the same percentage. Using satellite measurements of methane and carbon monoxide, Worden's team found the real decrease in methane emissions was almost twice as much as that assumption would suggest.

When the research team subtracted this large decrease from the sum of all emissions, the methane budget balanced correctly, with room for both fossil fuel and wetland increases. The research is published in the journal Nature Communications.

* Atmospheric methane concentrations are given by their weight in teragrams.
* One teragram equals about 1.1 million U.S. tons -- more than the weight of 200,000 elephants.
* Methane emissions are increasing by about 25 teragrams a year, with total emissions currently around 550 teragrams a year.

Most methane molecules in the atmosphere don't have identifying features that reveal their origin. Tracking down their sources is a detective job involving multiple lines of evidence: measurements of other gases, chemical analyses, isotopic signatures, observations of land use, and more. "A fun thing about this study was combining all this different evidence to piece this puzzle together," Worden said.

Carbon isotopes in the methane molecules are one clue. Of the three methane sources examined in the new study, emissions from fires contain the largest percentage of heavy carbon isotopes, microbial emissions have the smallest, and fossil fuel emissions are in between. Another clue is ethane, which (like methane) is a component of natural gas. An increase in atmospheric ethane indicates increasing fossil fuel sources. Fires emit carbon monoxide as well as methane, and measurements of that gas are a final clue.

Worden's team used carbon monoxide and methane data from the Measurements of Pollutants in the Troposphere instrument on NASA's Terra satellite and the Tropospheric Emission Spectrometer instrument on NASA's Aura to quantify fire emissions of methane. The results show these emissions have been decreasing much more rapidly than expected.

Combining isotopic evidence from ground surface measurements with the newly calculated fire emissions, the team showed that about 17 teragrams per year of the increase is due to fossil fuels, another 12 is from wetlands or rice farming, while fires are decreasing by about 4 teragrams per year. The three numbers combine to 25 teragrams a year -- the same as the observed increase.

Worden's coauthors are at the National Center for Atmospheric Research, Boulder, Colorado; and the Netherlands Institute for Space Research and University of Utrecht, both in Utrecht, the Netherlands.

Is the NSW Berejiklian Coalition Government taking the Norther Rivers bushfire risk level seriously?


The NSW Nationals Parks and Wildlife Service (NPWS) manages more than 870 national parks and reserves totalling over 7 million hectares.

With 22 per cent of the Clarence Valley covered by heavily timbered national parks and the entire NSW Northern Rivers region having 10 national parks, at least 9 nature reserves and 2 state forests, the risk of bushfires has always been high.

With climate change raising the fire risk and the NSW Berejiklian Coalition Government stripping the NWPS of personnel and funding, many local residents are beginning to worry.

The NSW Government’s Latest Attack On The Environment


How important is protection of the natural environment to the NSW Government? 
Many in the community believe that the Government gives it a very low priority.   There are even some who would assert that the NSW Coalition Government is conducting a war on the environment.
Concern about the Government’s environmental attitudes is the inevitable result of a series of its policies and legislation over recent years.  A few examples are its original very strong support for CSG and unconventional gas mining[1], its weakening of land-clearing and biodiversity protection laws[2], its strong support of coal mine expansions despite community opposition[3], and more recently, its plan to change the law to enable Lithgow’s Springvale Mine to stay open despite its threat to Sydney’s water catchment[4].
The latest major threat to the natural environment in NSW is the re-structure of the National Parks and Wildlife Service (NPWS).  The National Parks and Wildlife Service, a part of the Office of Environment and Heritage,  manages more than 870 national parks and reserves covering over 7 million hectares of land  which is more than 9% of the state’s land area.
The restructure which is currently under way involves the amalgamation of administrative areas, and either the loss of experienced officers or their demotion to what will be little more than clerical roles with substantially reduced salaries.  In addition there are serious concerns about the effect of the changes on fire-fighting capacity as well as on pest management.
The changes resulting from this restructure will have serious effects throughout the state.
Grafton on the NSW North Coast, for years an administrative centre for NPWS, will lose that function. Despite Grafton’s location in the geographical centre of the new region, the administrative headquarters is being transferred to Coffs Harbour. 
Clarence Valley locals, having seen over recent years the steady transfer of state government jobs from Grafton to Coffs Harbour, are angry about this.  What makes this decision even more nonsensical to some Clarence residents is that the Clarence Valley LGA (Local Government Area) contains one of the biggest areas of national parks on the North Coast.  Clarence Valley Mayor, Cr Jim Simmons, pointed out recently that the Clarence had 2,262 sq km of national parks, 22% of the Council area, while Coffs Harbour, has only 42 sq km – a mere 4% of the Coffs council area.
While there is concern about job losses, the loss of expertise in the Service and the impact of this drawn-out and unfair process on the Service officers, there is another major concern – the long-term effect on our very important national parks estate.  Despite the claims by politicians, including the Nationals Member for Clarence, Chris Gulaptis, this is a cost-cutting exercise at a time when the Government has boasted about a record budget surplus of $4.5 billion.  Any claim that it is not cost-cutting when the NPWS budget has been reduced by $121 million is obviously ludicrous.
However, it is probably more than just a cost-cutting exercise.  It is almost certain that it is at least partly driven by the ideology of the Coalition Government a core part of which, according to John Menadue[5], is commercializing and privatising public assets.
With reference to this, Menadue said: “A clear case at the moment is the NSW National Parks and Wildlife Service. It is being deliberately underfunded and forced to seek private funding and promoting commercial access to public parks.
“Yet this is happening when, with growing population density, we have a greatly increased need for public parks, gardens and open space. Furthermore, we were able to fund our public parks for decades in the past when we were much poorer than we are today. We need to protect our parks more than ever and we have more money to do so. Yet state governments are screwing national parks with funds to force commercialization and privatization.”
In the same post Menadue quoted figures from John Benson about the downgrading of the NPWS[6]. The number of rangers has been reduced by more than 90 over seven years. Only two of 14 regional managers have been appointed after a restructure and a similar threat faces critical staff at the area management level. Staff is so reduced in some regions that basic amenities cannot be maintained and a lack of field staff presence disappoints public visitor expectations.”
Despite all the spin from politicians and bureaucrats, it is obvious that the government intends to downgrade our national parks and is setting up the National Parks and Wildlife Service for failure. If the community, including that in our local area, does not protest vehemently enough, we will be stuck with this vandalism until this arrogant government is removed.
