When did Sydney become the capital of New South Wales?
History of Sydney
Between 1788 and 1792, convicts and their jailers made up the majority of the population; in one generation, however, a population of emancipated convicts who could be granted land began to grow. These people pioneered Sydney's private sector economy and were later joined by soldiers whose military service had expired, and later still by free settlers who began arriving from Britain. Governor Phillip departed the colony for England on 11 December 1792, with the new settlement having survived near starvation and immense isolation for four years.
