In 1901, the separate colonies in Australia united to form the nation of Australia.

The Short Version

The historical record firmly supports this claim. Multiple high-authority Australian institutions — including the Australian Parliament and the National Museum of Australia — confirm that six separate British colonies federated on 1 January 1901 to form the Commonwealth of Australia. While federation was legally enabled by a British Act of Parliament and full sovereignty came later, these are standard contextual details that do not undermine the claim's core accuracy as commonly understood.

Caveats

Federation was legally enabled by the UK Parliament through the Commonwealth of Australia Constitution Act 1900, not by fully sovereign colonies acting independently.
What formed on 1 January 1901 was the Commonwealth of Australia — a self-governing dominion within the British Empire. Full legal independence from the UK came through later legislation (e.g., Statute of Westminster, Australia Acts).
Exactly six colonies federated as founding states; territories such as the Northern Territory were not among the federating colonies.
