Australia has been in less than zero population growth from natural increase for over 40 years and continues to supplement its short & long term production & workforce needs through overseas migration


Births, Australia: Statistics about births and fertility rates for Australia, states and territories, and sub-state regions, Reference period 2022, Australian Bureau of Statistics, statistical series.

Total fertility rate is the number of registered births per woman.

Crude birth rate is the number of births per 1,000 estimated resident population.

Net reproduction rate is the average number of daughters surviving to reproductive age per woman.

Sex ratio is the number of male births per 100 female births.

All statistics are based on year of registration unless otherwise specified.



Australian Bureau of Statistics (ABS), media release, 18 October 20232:


Australian women are having fewer children, and having them later in life according to data released today by the Australian Bureau of Statistics (ABS).


Emily Walter, ABS head of demography said; “Today’s data continues a trend we’ve seen in births over the last 40 years, with the average age of both mothers and fathers steadily increasing since the mid 1970s.


In 1975, less than 20 per cent of births were to mothers who were between 30 and 39 years old, but now nearly 60 per cent of births are to mothers in this age group.”


Australian women are also having fewer children. The total fertility rate has remained lower than the replacement rate (considered to be 2.1 babies per woman to replace her and her partner, in the absence of overseas migration) since 1976.


In 2022, this was 1.63 births per woman, which was lower than the 2021 rate of 1.70 births per woman, but higher than the 1.59 births per woman recorded in 2020.


Although total fertility remains low, the fertility rate for women in their late 30s and early 40s has significantly increased.


From 1991 to 2022, the fertility rate of mothers aged 35-39 years has almost doubled from 36.0 to 69.3 births per 1,000 women, and for mothers aged 40-44 years, it has nearly tripled from 5.5 to 15.8 births per 1,000 women.


In contrast, the fertility rate of teenage mothers has reached an all-time low of 6.8 births per 1,000 women, from 22.1 births per 1,000 women in 1991.” Ms Walter said.


The falling fertility rates of women aged under 30 years and the rising fertility rates of women in their thirties and early forties, are consistent with women having their first and subsequent births later in life.


This shift towards older parenthood largely follows from young people tending to reach the milestones which usually precede parenthood (i.e. leaving the parental home, gaining economic independence, and marrying or forming long-term de facto relationships) later than was seen in previous decades.


In 2022:

  • Australia registered a total of 300,684 births, a decrease of over 9,000 from 2021 but higher than 2020 numbers.

  • Women aged 30-34 years had the highest fertility rate (114.9 births per 1,000 women or about 1 birth for every 9 women), followed by women aged 25-29 years (83.0 births per 1,000 women).

  • Of women aged 15-49 years, women in the 45-49 years cohort continue to have the lowest fertility rate (1.1 babies per 1,000 women).

  • The fertility rate of women aged 15-19 years was the lowest on record (6.8 babies per 1,000 women).

  • The Northern Territory recorded the highest total fertility rate (1.73 babies per woman), followed by New South Wales and Queensland with 1.71 babies per woman.

  • The Australian Capital Territory had the lowest total fertility rate (1.41 babies per woman).


When one looks at the seven local government areas which make up the NSW Northern Rivers region, in 2022:


Ballina – 439 registered births, total fertility rate 1.83

Byron – 364 registered births, total fertility rate 1.42

Clarence Valley – 575 registered births, total fertility rate 1.42

Kyogle – 95 registered births, total fertility rate 2.40

Lismore – 466 registered births, total fertility rate 1.84

Richmond Valley – 262 registered births, total fertility rate 2.27

Tweed – 1,060 registered births, total fertility rate 2.00.

It would appear that despite high rainfall & rain dumps, east coast low storms and record floods, in 2022 the stork still managed to deliver a good many bundles across this region.

Ongoing concerns about sustainable water supply and environmental risk, Mullum NSW


Laverty's Gap Weir

Byron Echo, Letters, 5 April 2023:



It seems our elected councillors are at odds with non-elected Council staff over the future of Mullum’s water supply.



My concern is that there is no consideration in the current arrangements for environmental flow in the Wilsons Creek/River below Lavertys Gap weir. This obviously didn’t seem like a big issue when the agreement was drawn up several decades ago and the population of the area was a fraction of what it is today.



However, our population is growing and every new house has flush toilets, showers and gardens to water. Might these houses be required to at least have water tanks as every roof is a perfect water catchment?



In the last drought (2019–20) the area downstream of the weir was almost stagnant. This is a vital habitat for platypus and many other native species. Local residents also rely on the creek to water food gardens.



It is crucial that we consider the long-term health of this important waterway and the survival of both native and human inhabitants.



We need to act now for the future and put in place a requirement for realistic environmental flow.



Please speak up for the river by contacting Council: council@byron.nsw.gov.au

The weir at Laverty's Gap supplies water to Mullumbimby. It is a Heritage-listed ageing structure in need of repair, which appears to block fish passage in that section of the Wilsons River and operates under a licence that does not require release of environmental flows to water the downstream environment. 


There is community concern that weir capacity only meets current population demand as the weir water supply currently services est. 1,890 residential and non-residential properties and, will not be able to meet need in future droughts given access to emergency water supply is limited to only part of the town. 


Water restrictions were imposed in Mullumbimby during the droughts of 2002/03, 2006/07 and 2019/20 and, there is community concern about the degree to which climate change will exacerbate future droughts.
