Unley, SA
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Unley is an established inner-southern suburb of Adelaide, just beyond the southern Park Lands and the seat of the City of Unley. It takes its name from the family of the wife of Thomas Whistler, on whose land the suburb was laid out around 1857. This is Kaurna country — the people of the Adelaide Plains — and in the colony's early decades the land was cleared to run sheep and cattle and to plant vineyards and orchards, with the post office opening as early as 1850. Trams once ran down Unley Road until the 1950s, and over time the suburb grew into a busy commercial strip just south of the city, home to a notable Greek Australian community. The Test cricketers Greg and Ian Chappell were both born here.
