About St Agnes
St Agnes is a suburban locality in Adelaide's north-eastern foothills, situated within the City of Tea Tree Gully approximately 17 kilometres from Adelaide's CBD. Covering 2.6 square kilometres at an elevation of 157 metres, the suburb has a population of 4,233 and a median age of 44. The median household income of $1,557 per week reflects a comfortable middle-income community shaped by a diverse mix of English, German, Italian, and South Asian ancestry — with over 1,000 residents born overseas.
St Agnes is well-positioned near Tea Tree Plaza, one of Adelaide's major suburban shopping centres, and benefits from the O-Bahn Busway — one of Australia's fastest dedicated bus rapid transit corridors — providing swift connections to the Adelaide CBD in under 30 minutes. A range of local schools, including government, Catholic, and independent options, serve a community of established families and long-term residents, while the elevated hillside setting offers pleasant views across metropolitan Adelaide. The suburb's quiet character, affordability relative to inner-Adelaide, and reliable transit links make it a practical and popular choice for families and commuters.
