South Australia House Suburbs

Overview

South Australia’s resident population was 1,806,599 in December 2021, with more than two‑thirds of those people living in the Greater Adelaide region; the state’s second‑largest centre, Mount Gambier, recorded a population of 26,878. This concentration makes the capital’s housing stock the dominant component of the state’s rental market, shaping overall affordability dynamics.

The state’s economy is anchored by agriculture, manufacturing and mining, while health‑care and social assistance represent the largest employment sector, followed by retail, education, manufacturing and construction. These employment patterns generate strong and steady demand for rental housing, particularly in Adelaide, where affordability remains a focal point for both investors and tenants.
