Alexandrina Onkaparinga

Onkaparinga and Alexandrina are nearby South Australian areas with very different characters. Onkaparinga is more urban and connected, with a somewhat walkable layout and far more public transport options. In contrast, Alexandrina is mostly car-dependent and has a much older population; the typical resident there is 53, compared to 41 in Onkaparinga. This age gap has widened since 2011, and it is reflected in the housing, with 44.3% of Alexandrina homes owned outright, compared to 30.4% in Onkaparinga.

Both areas are remarkably similar in their overall advantage and have nearly the same share of First Nations residents. While they share these traits, other gaps are growing. Since 2011, the difference in the number of adults working or looking for work has increased, with Onkaparinga now far higher at 60.4% compared to 48.6% in Alexandrina. Onkaparinga also has a higher proportion of people born overseas and a larger share of children under 15.
