Sydney
Under the reign of Queen Victoria federation of the six colonies occurred on 1 January 1901. Sydney, with a population of 481,000, then became the state capital of New South Wales. The Great Depression of the 1930s had a severe effect on Sydney's economy, as it did with most cities throughout the industrial world. For much of the 1930s up to one in three breadwinners was unemployed. Construction of the Sydney Harbour Bridge served to alleviate some of the effects of the economic downturn by employing 1,400 men between 1924 and 1932. The population continued to boom despite the Depression, having reached 1 million in 1925.
Statute of Westminster Adoption Act 1942
New South Wales was founded as a British colony in Sydney in 1788. Other colonies split away from New South Wales or were separately established over the Australian continent in the ensuing decades. The colonies became self-governing during the second half of the 19th century, starting with Victoria in 1852, although well before this time, all of the colonies had non-elected Legislative Councils to advise their respective Governors on matters of administration.
