South Australia SA
South Australia (~1.85 million) hosts Australia's most affordable mainland capital — Adelaide median prices remain well below Sydney, Melbourne, or Brisbane. The state has a slower-growth profile than the eastern states, an aging population in regional areas, and a distinctive industrial mix: defence and space contracting (Adelaide is home of the future AUKUS submarine fleet and the Australian Space Agency), advanced manufacturing, and viticulture (Barossa Valley, McLaren Vale, Coonawarra, Clare Valley together producing nearly half Australia's wine). Mediterranean climate dominates the populated south, while the north is largely arid outback. Adelaide is laid out on a planned grid with extensive parklands and hosts world-class cultural festivals (WOMADelaide, Adelaide Festival, Fringe). Outside the capital, regional centres Mount Gambier, Whyalla, Murray Bridge, and Port Lincoln each have specialised local economies — fishing, steel, agriculture, mining services.
South Australia median house prices range from $124,000 to $2.8 million.
