Hi! Thanks for the question.
The official numbers for the historical population statistics of
Australia can be found at the website of the Australian Bureau of
Statistics. The figures take into account the time period of 1788 up
to 2002. This is the latest figures from the Australian government
Australia had its sharpest population growth rate during the 1950's.
The growth rate at that time was 2.3%, the highest in Australia's
"Population growth results from natural increase and net overseas
migration. Australia's population grew from 3.8 million at the
beginning of the 20th century to 19.7 million in 2002. During the
1950s, Australia experienced consistently high rates of growth, with
an average annual increase of 2.3% from 1950 to 1959. However, during
the 1930s, Australia experienced relatively low growth, with an
average annual increase of 0.9%."
"In 1901 the rate of natural increase was 14.9 persons per 1,000
population. Over the next four decades the rate increased (to a peak
of 17.4 per 1,000 population in the years 1912, 1913 and 1914), then
declined (to a low of 7.1 per 1,000 population in 1934 and 1935). In
the mid- to late-1940s the rate increased sharply as a result of the
beginning of the baby boom and the immigration of many young people
who then had children in Australia, with a plateau of rates of over
13.0 persons per 1,000 population for every year from 1946 to 1962."
"Since 1962 falling fertility has led to a fall in the rate of natural increase."

I was also able to find two additional interesting historical
population trends in Queensland and in Tasmania.
"The first human inhabitants of what is now Tasmania arrived more than
35,000 years ago, crossing the land bridge that then connected
Tasmania to the Australian mainland. The total population, before
white settlement, has been estimated at between 5,000 and 10,000."
"The post-war baby boom and gains from overseas immigration resulted
in an annual population increase of 1.5% in the 35 years from 1945 to
1980, more than double the pre-war rate."

"On separation from the Colony of New South Wales in 1859,
Queensland's population was 23,520. Among the Australian colonies,
only Western Australia had a smaller population at the time.
Queensland's population has increased each year since, with the
exception of 1916 and 1946, which were affected by World Wars I and II
"Queensland's population exceeded a quarter of a million in 1883,
reached half a million in 1901, 1 million in 1938 and 2 million in
1974. It took only another 18 years for the Queensland population to
exceed 3 million, which occurred in March 1992."
