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.
New South Wales
The Colony of New South Wales was founded as a penal colony in 1788. It originally comprised more than half of the Australian mainland with its western boundary set at 129th meridian east in 1825. The colony also included the island territories of New Zealand, Van Diemen's Land, Lord Howe Island, and Norfolk Island. During the 19th century, most of the colony's area was detached to form separate British colonies that eventually became New Zealand and the various states and territories of Australia. However, the Swan River Colony has never been administered as part of New South Wales.
