Shark Attacks in Australia: setting the record straight


On Saturday 23 December 2017 Liberal MP for Kooyong and Minister for Environment and Energy Josh Fydenberg penned a media release claiming big bad sharks were about to overwhelm his home state, Western Australia.

The shark in question is the Great WhiteCarcharodon carcharias, classified as vulnerable on the IUCN Red List of Threatened Species and currently protected as vulnerable and migratory in the Australian EEZ and state waters under the Environment Protection and Biodiversity Conservation Act 1999.

Federal Minister Frydenberg home for the parliamentary break is of course playing local WA politics during the silly season - having forgotten or ignored the fact that the White Shark (Carcharodon carcharias) Recovery Plan falls within his ministerial portfolio.

However, it does appear hard for many other politicians to accept that, in the 224 years of human-shark interaction record keeping undertaken since 1788, the number of deaths due to shark attack barely equates to one death per year along the est. 59,736 kilometres of coastline in this country.

Here are a few facts which are on that record.

A ‘shark attack’ is defined in the ASAF as any human–shark interaction where either a shark (not in captivity) makes a determined attempt to attack a person who is alive and in the water or the shark attacks equipment held by the victim or attacks a small-water craft containing the victim…..

Over the 218 years for which records were available, there have been 592 recorded unprovoked incidents in Australian waters, comprising 178 fatalities, 322 injuries and 92 incidents where no injury occurred. Most of these attacks have occurred since 1900, with 540 recorded unprovoked attacks, including 153 fatalities, 302 injuries and 85 incidents where no injury occurred. Attacks have occurred around most of the Australian coast, most frequently on the more densely populated eastern coast and near major cities…

In the 20 years since 1990, there have been 186 reported incidents, including 22 fatalities (Table 1). This represents a 16% increase in reported attacks during 1990–1999 and a 25% increase over the past 10 years (Fig. 3). The majority of attacks occurred in New South Wales (NSW) with 73 incidents (39%), then Queensland with 43 incidents (23%), Western Australia (WA) with 35 incidents (19%), South Australia with 20 incidents (11%), Victoria with 12 incidents (6%), Tasmania with two incidents (1.5%) and Northern Territory with one incident (0.5%)…..

SHARK ATTACKS AUSTRALIA-WIDE JANUARY 2012 to NOVEMBER 2017

2012 – 22 attacks (8 provoked) in total, 2 fatalities and 14 attacks involving injury

2013 – 14 attacks (4 provoked) in total, 2 fatalities and 10 attacks involving injury

2014 – 23 attacks (12 provoked) in total, 5 fatalities and 14 attacks involving injury

2015 – 33 attacks (11 provoked) in total, 2 fatalities and 23 attacks involving injury

2016 – 26 cases (9 provoked) in total, 2 fatalities and 16 attacks involving injury

2017 – 19 attacks (2 provoked) in total, 1 fatality and 11 attacks involving injury [up to 24 November 2017]

[Taronga Conservation Society AustraliaThe Australian Shark Attack File (ASAF), Annual Report Summary]

Throughout the world, human populations are increasing whereas shark populations are decreasing because of direct and indirect human impact (Castro et al. 1999). There is evidence that at least some shark populations in Australia have declined as a result of commercial and recreational fishing pressure (Punt and Walker 1998; Punt et al. 2000; Simpfendorfer et al. 2000; McAuley et al. 2007…..

Patterns of attack have changed substantially over time as a result of the changing population and human behaviour. If human activity related to water-based activities and the use of beaches, harbours and rivers continues to change, we can expect to see further changes in the patterns, distribution, frequency and types of attacks in the future. Encounters with sharks, although a rare event, will continue to occur if humans continue to enter the ocean professionally or for recreational pursuit.

It is important to keep the risk of a shark attack in perspective. On average, 87 people drown at Australian beaches each year (SLSA 2010), yet there have been, on average, only 1.1 fatalities per year from shark attack over the past two decades. It is clear that the risk of being bitten or dying from an unprovoked shark attack in Australia remains extremely low.

[CSIRO, Marine and Freshwater Research, 2011, Shark Attacks In Australia]

ABC News, 8 February 2016:

The shark nets used on Sydney beaches in New South Wales do nothing to reduce the chance of attacks, a statistical analysis has found.

Associate Professor Laurie Laurenson from Deakin University's School of Life and Environmental Sciences has analysed 50 years of data about shark mitigation programs and coastal populations in NSW and South Africa.

He told Four Corners reducing the density of local shark populations did not reduce the likelihood of shark attack.

"I can show statistically that there is no relationship between the number of sharks out there and the number of shark attacks," he said.

"It's just simply not there … I'm surprised that it's not there, but it's not there."

It is the first time a comprehensive analysis has been done in an effort to link populations of sharks and people and the number of attacks in netted areas.

The findings are included in an unpublished paper which is in the process of being peer reviewed.

"We could not demonstrate a statistically significant relationship between the density of the sharks and the number of attacks in the localised area around Sydney where there have been historically large numbers of attacks and there've been large numbers of mitigation programs," Dr Laurenson said.

In early 2017 North Coast Voices observed about the predictably lethal consequences of shark netting that the NSW North Coast marine species protection record is a very sad affair.

Climate denialists discuss suing a company for NOT increasing pollution


There are times when one wonders just how crazy the people associated with The Heartland Institute can get – then this sentence pops up a 6-page email from the Institute’s CEO Jim Bast to its Director of Communications Jim Lakely:

sue a company for not increasing CO2 emissions, force a court to consider the evidence on CO2 benefits.

The October 2017 email exchange can be read at https://www.documentcloud.org/documents/4112082-Joe-Bast-Email.html

A list of people on The Heartland Institute’s mailing list who would be receiving such suggestions, courtesy of DeSmog Blog:

Heartland Institute's Climate Scientists Mailing List
Heartland Institute's Climate Economists Mailing List 

As far-right global warming denialists in the Turnbull Government tend to mimic US moves against science-based policy, I suspect that this pared-down version of the latest Heartland playlist will be used in Australia in 2018 whenever they plan strategy or are quoted in the media on the subject of climate change:

* be briefing news reporters and news readers
* simplify the issue by focusing on one or only a few arguments and images
* identify a few good spokespersons and focus on promoting them
* stop chasing the other side’s latest argument and focus instead on the benefits of CO2
* focus on the “tuning scandal” that discredits the models
* turn debate from referring to median temperatures to high temperatures, which show no trend
* find independent funding for [insert climate change denier of choice]
* respond to [insert climate report of choice]
* get good people onto EPA advisory boards
* we need to be able to say “EPA is reconsidering whether CO2 is a pollutant”
* document instances where EPA etc. fail to cite research findings that contradict their agenda
* conduct a new survey of scientists to refute the 97% consensus claims
* sue a company for not increasing CO2 emissions, force a court to consider the evidence on CO2 benefits
* read The Business of America is Lobbying to understand the tactics of those we are really up against
* never use the phrases “windmill farms,” “all of the above,” “carbon pollution,” “social cost of carbon,” or “air pollution”
* use “industrial windmills,” “reliable and affordable,” “carbon dioxide emissions,” “benefits and costs of fossil fuels,” and “air quality”
* emphasize that we are pro-science and pro-environment… and the other side is not
* always think about what is most important to your audience
* when being interviewed, deliver your headlines first, don’t let the reporter lead you astray or cut you off
* prepare to answer the “what if you are wrong?” question with “what if you are wrong? How much damage will you have caused by costing the average household $4,000 a year for nothing?”
* fundamentally challenge, reform, or replace the [insert government agency of choice], the source of much pseudoscience
* stop funding “more research”
* clearly distinguish “safe” – a policy concept – from “risk” – a scientific concept, and keep scientists from pontificating on the former and advocates from misrepresenting the latter
* doubling the concentration of CO2 in the atmosphere would increase plant productivity by 35%.
* any SCC calculation that doesn’t include the benefits of CO2 should be rejected out of hand

Welcome to the dog whistle season in Australia


Determined to keep the pot on the boil during their extended holiday break government ministers and humble backbenchers tend to release selected dog whistles to the media .

It appears we might have Liberal Senator for Tasmania Eric Abetz to thank for this one elicited by Treasury Budget Policy Division's answer to one of his Questions on Notice on or about 11 December 2017.

SBS News, 29 December 2017:

Working Australians are forking out roughly $83 per week to fund the nation's welfare bill.

Average taxpayers are handing over $35 every week to prop up aged pensioners, $20 per week to pay for family benefits and $17 to support Australians with disabilities.

Just over $6 per week goes to the unemployed, while $9 goes towards repaying interest on government debt, according to figures released to a Senate committee.

Going to the source it appears that based on a fictional, average "someone who owes $11,424 in tax" in 2014-15, the extended estimates breakdown works out at a notional: 

$42.25 per week for health care; 
$35.03 for aged pensions;
$20.42 for family payments (includes child care & paid parental leave);*
$19.65 for defence of the country; 
$18.50 as the contribution to education funding; 
$17.34 to cover disability payments (includes NDIS);
$9.11 for interest payments on federal government debt; 
$6.26 towards unemployment benefits;
$4.11 other;*
$3.32 for industry assistance;
$2.94 for public order & safety; 
$2.61 for housing & community; and 
$38.11 cents per week for the remaining seven listed categories.
* Classified in the media as "Welfare" with a rounded down total of $83 a week 

Both Senator Abetz and the media remain silent on the actual cost to the average taxpayer of the full range of business/company tax concessions. They also remain silent on how individuals can structure tax offsets and investment properties in order to reduce taxable income to zero or how personal income tax rebates at the end of each financial year may affect those weekly notional figures cited as a drain on taxpayers. However, Treasury does not keep quiet on the subject of revenue foregone and helpfully releases a Tax Expenditure Statement at the beginning of each year. 

In fact if Senator Abetz wanted to be honest he would have included a question concerning financial benefits from taxation revenue going to all Australian households for 2016-17. In 2015-16 that came to $105.8 billion in federal monetary transfers derived from taxation revenue in that financial year or notionally around est. $94 a week per person based on the number and average size of all households in 2016. In addition each person would receive the equivalent of est. $40 per week as 'in kind' government goods & services.

Which means a great many working Australians receive more from the collective income tax revenue pool than they actually pay out in individual income tax. 

Indeed Treasury's 2017-18 microsimulation model of Personal Income Tax and Transfers clearly shows that, based on equivalised disposable income quintiles, an est. 60 per cent of all Australian families pay no tax or less than est. $2,000 in annual income tax once government transfers received are deducted. Included in this percentage are working families with equivalised disposable incomes below $67,000pa.

It should be noted that the aforementioned fictional person owing an estimated "$11,424 in tax" is likely to have an equivalised disposable income well in excess of $67,000pa.

Both the microsimulation model and the fictional person make nonsense of the bald assertion that; "Working Australians are forking out roughly $83 per week to fund the nation's welfare bill".

In Australia every citizen of workforce age and over pays tax - even if its just the Goods and Services Tax (GST). And every citizen of any age receives a benefit from one or more forms of tax revenue redistribution in cash and/or kind, so it is the height of hypocrisy to argue that this benefit only goes to people receiving Centrelink/Veterans Affairs payments from the state and that the entire cost of any welfare 'bill' falls squarely on the shoulders of those with other incomes. 

Whoever authorised this particular media swipe at welfare recipients has forgotten that the Turnbull Government had been putting out versions of this story all last year and, not only has it grown whiskers but the electorate has become somewhat resistant to such tired political rhetoric.

No matter how hard political commentators try to classify receiving a government cash transfer as a form of social deviance, Australian society cannot be neatly divided into "lifters and leaners", "workers and bludgers" or "us and THEM".

Over the course of a lifetime everyone of us could be considered some or all of those things at some point, as we travel from childhood dependency through to adulthood and onto the grave.

NOTE:

Australian Parliamentary Library, What counts as welfare spending?, extract, 21 December 2015:

At its broadest welfare can be used to refer to all of the programs and services that make up the welfare state. This can include health and education, as well as income support payments such as the Age Pension, Carer Payment, Disability Support Pension and Newstart Allowance.

Welfare can also refer to the administrative category of ‘social security and welfare’. This category is used in budget papers and includes spending on aged care, child care, the National Disability Insurance Scheme (NDIS), family assistance payments and income support payments.

Welfare can also refer to a much narrower (and less clearly defined) category of spending on income support payments to people of working age. These welfare payments are means-tested benefits provided in cash. They go to people of working age who are not participating in paid employment or other activities such as education or vocational training. The term welfare can be applied loosely to spending that meets some or all of these criteria. It is a moral or political category rather than a legal or administrative one. It is often associated with the idea that recipients have not earned an entitlement to payments through contributions to the community.

Use of this political category of welfare has become increasingly common in Australian political debate. The category tends to include unemployment payments, such as Newstart Allowance, and payments to people of working age claiming support on the grounds of disability or single parenthood.

Statistics on welfare spending play a central role in debates over government policy. However, in public debate it is not always clear which category these statistics refer to. Sometimes statistics that refer to the broad category of social security and welfare are presented as if they referred to the narrower political category of welfare.

If public debate is to be informed by facts, commentators need to pay close attention to the way categories such as welfare are defined. When categories remain vague and ambiguous, the statistics can conceal as much as they reveal.

A reminder that the Government of Japan still allows its whalers to slaughter whales in the Antarctic section of the Australian Whale Sanctuary


Australian Whale Sanctuary, www.environment.gov.au
In 2015 Environmental Defenders Office ( EDO NSW) received instructions from Sea Shepherd Australia to help them obtain information from the Commonwealth Government relating to illegal whaling practices by Japanese vessels in the Southern Ocean

The resulting application was refused by the Department of Immigration and Border Protection, requiring EDO NSW to press their client’s case with the Commonwealth Information Commissioner. 

In May 2017, the Information Commissioner ordered the release of the documents and this video was made public in the following November.

Turnbull & Co have to make up a lot of ground six months out from the start of the federal general election countdown


According to Newspoll Malcolm Bligh Turnbull commenced the new year with only 31 per cent of the population approving of his performance as prime minister and only 35 per cent of voters willing to give his government first preference at the next federal election.

An election which is due to be called sometime between 4 August 2018 and 18 May 2019.

As for the swing against the Turnbull Government in mainland states………

The Australian, 26 December 2017:

The Coalition has suffered a two-point fall in its two-party-preferred vote in the five mainland state capital cities since September to trail Labor 55-45.

On a two-party-preferred basis, Labor leads 55-45 in Queensland, 54-46 in NSW and Victoria and 53-47 in both South Australia and Western Australia. This represents a 4 per cent swing nationally to Labor, which, if ­repeated at the next election, could result in the loss of between 20 and 30 seats for the Liberal and Nationals parties.

The final Newspoll analysis of the year threatens to dampen the buoyancy in the Coalition parties that flowed from Mr Turnbull ­finishing the year achieving victories in two by-elections triggered by the High Court ruling on dual citizenship and claiming the scalp of disgraced Labor senator Sam Dastyari as it pursued popular new laws to curb foreign interference and influence.
