Overview
Adelaide is the capital of South Australia, home to 1.4 million people. It uses the unique Australian Central Standard Time (ACST, UTC+9:30) — a half-hour offset that is a direct legacy of the Adelaide Observatory's calculation of local mean time in the 1890s. Australia's most 'planned' capital, laid out in an ordered grid surrounded by parklands, it is renowned for food and wine culture (Barossa Valley and McLaren Vale are 1 hour away) and the Adelaide Fringe, the world's second-largest arts festival.

📜 History & Origins
The Kaurna people inhabited the Adelaide Plains for thousands of years. The city was founded in 1836 as a planned free settlement — notably, no convict labour was used, distinguishing it from other Australian colonies. Colonel William Light surveyed and designed the city in a grid pattern with a ring of parklands, a plan so admired it was completed in just 13 weeks. Adelaide was one of the first cities in the world to give women the right to vote (1894).
