Millbrook

12 km²

Far older than most similar areas, Millbrook is a small Adelaide Hills community where the typical resident is 50. This quiet neighbourhood is largely made up of older adults and couples, with very few children compared to the state average. While it feels peaceful, the area is heavily car-dependent due to its steep terrain and a lack of nearby shops or services. It is a place where many residents own their homes outright and enjoy a high level of professional and managerial employment.

Millbrook's schools draw a more advantaged community than local incomes would suggest.
