About One Tree Hill

One Tree Hill is a semi-rural town on the north-eastern fringe of Adelaide, situated approximately 28 kilometres north-north-east of the Adelaide CBD within the City of Playford local government area. The locality covers over 23 square kilometres at an elevation of around 241 metres and had a population of 1,043 at the 2021 Census. Established as early as 1851 — named after the 'One Tree Hill Inn', itself named for a giant red gum that once marked the local crossroads — the area retains a historic, semi-rural character at the edge of the Adelaide Plains. The population is predominantly Australian and English in ancestry, with a median age of 45, and households here tend to be owner-occupiers on larger rural blocks.

One Tree Hill sits at the meeting point of suburban growth and open countryside, with the expanding Elizabeth corridor to the west and the Para Wirra Recreation Park to the east offering bushland walks, wildlife spotting, and mountain biking. The locality has a primary school, a hotel, and some local services, though residents rely on nearby Elizabeth or Greenwith for major shopping and medical services. The community has a strong rural and semi-acreage character that appeals to families and retirees seeking space and quiet, while remaining within reasonable reach of Adelaide's northern suburbs. Public transport is limited and a car is the primary mode of transport.

One Tree Hill falls under postcode 5114 and is governed by Playford Council (LGA). For state elections, residents vote in the King electorate.
