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 Western Australia
Although many expeditions visited the coast during the next 200 years, there was no lasting attempt at establishment of a permanent settlement until December 1826 when an expedition on behalf of the New South Wales colonial government, led by Major Edmund Lockyer, landed at King George Sound. On 21 January 1827 Lockyer formally took possession of the western third of the continent of Australia for the British Crown. This was followed by the establishment of the Swan River Colony in 1829, including the site of the present-day capital, Perth. The harsh conditions faced by the settlers resulted in population growth being minimal until the discovery of gold in the 1880s. Since the gold rush, the population of the state has risen steadily, with substantial growth in the period since World War II.
