Demographics of Australia
demographics of country
The population of Australia is estimated to be 27,994,737 as of 26 June 2026. It is the 54th most populous country in the world and the most populous Oceanian country. Its population is concentrated mainly in urban areas, particularly on the Eastern, South Eastern and Southern seaboards, and is expected to exceed 30 million by 2031.
Australia's population has grown from an estimated population of between 300,000 and 2,400,000 Indigenous Australians at the time of British colonisation in 1788 due to numerous waves of immigration during the period since. Also due to immigration, the European component's share of the population rose sharply in the late 18th and 19th centuries, but is now declining as a percentage.
Australia has an average population density of 3.7 persons per square kilometre of total land area, which makes it one of the most sparsely populated countries in the world. This is generally attributed to the semi-arid and desert geography of much of the interior of the country. Another factor is urbanisation—with 89% of its population living in a handful of urban areas, Australia is one of the world's most urbanised countries. The life expectancy of Australia in 2015–2017 was 83.2 years, among the highest in the world.

“Demographics of Australia” enters the record as demographics of country. Crown Archives preserves that source wording while asking what Demographics, Australia and demographics can confirm, complicate or overturn.
Why this record matters
“Demographics of Australia” is worth following because a concise public description often conceals a longer documentary argument. Here, Demographics, Australia and demographics provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 18, 2026. The linked authority identifier is Q2088388. The first chronological checks are 2026, 2031, 1788 and 2015.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
