The South Australian Colonization Act received the royal assent of King William IV on 15th August 1834, the first colonists arriving on 20th July 1836 and landing on Kangaroo Island, the first place in South Australia to be settled.
The new Governor of South Australia, John Hindmarsh, arrived on 28th December 1836, together with the first Surveyor-General of South Australia, Colonel William Light.
Adelaide is, of all the Australian capital cities except Canberra (which dates from almost a century later), that which shows the greatest influence of thoughtful planning. In its centre it is the work of one man, Colonel William Light. He had first to choose a site for his capital. Despite opposition, he chose Adelaide and commenced his survey, at the junction of the present North and West Terraces, on 11th January 1837.
