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.
History of Australia (1851–1900)
In 1858 a new gold rush began in the far north, which led in 1859 to the separation of Queensland as a new colony. New South Wales thus attained its present borders, although what is now the Northern Territory remained part of the colony until 1863, when it was handed over to South Australia. The separation and rapid growth of Victoria and Queensland mark the real beginning of New South Wales as a political and economic entity distinct from the other Australian colonies. Rivalry between New South Wales and Victoria was intense throughout the second half of the 19th century, and the two colonies developed in different directions. Once the easy gold ran out by about 1860, Victoria absorbed the surplus labour force from the gold fields in manufacturing, protected by high tariff walls. Victoria became the Australian stronghold of protectionism, liberalism and radicalism. New South Wales, which was less radically affected demographically by the gold rushes, remained more conservative, still dominated politically by the squatter class and its allies in the Sydney business community. New South Wales, as a trading and exporting colony, remained wedded to free trade.
