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.

After a period of rapid growth, further discoveries of gold in Victoria began drawing new residents away from Sydney towards Melbourne in the 1850s, which created a strong rivalry between Sydney and Melbourne that still exists to this day. Nevertheless, Sydney exceeded Melbourne's population in the early twentieth century and remains Australia's largest city. Following the depression of the 1890s, the six colonies agreed to form the Commonwealth of Australia. Sydney's beaches had become popular seaside holiday resorts, but daylight sea bathing was considered indecent until the early 20th century.
