The Unley electorate is situated south of the Adelaide CBD and parklands and is a largely residential area of approx. 12.5 km2 (it is the smallest seat geographically due to little open space and higher density of housing).

Unley also has some of Adelaide’s grand old stone homes on large blocks. Protecting this element of its character is a hotly debated topic. Strip shopping still exists on all main roads, and each road has an active traders association.

The Unley electorate is bounded by Cross Road to the south, Greenhill Road to the north, Goodwood Road to the west and Portrush Road to the east. It abuts the electorates of Adelaide to the north, Waite to the south, Bragg to the East and Badcoe to the west. The electorate of Unley sits within the two federal seats of Adelaide and Sturt.

The electorate includes the suburbs of Eastwood, Glenside, Frewville, Fullarton, Glenunga, Glen Osmond (part) within the city of Burnside. Goodwood, Wayville, Highgate, Hyde Park, Malvern, Millswood (part), Myrtle Bank, Parkside, Unley, Unley Park within the City of Unley.
