O'Halloran Hill (SA 5158): property prices & suburb profile

O'Halloran Hill property prices

The typical O'Halloran Hill house sold for around $855,000 in the year to 2026-Q2, +128.0% over 10 years and +97.0% over 5 years.

• Medians are published by Land Services SA per suburb; we do not have individual sale records for this state, so there is no street-level breakdown on this page (our New South Wales pages have one).
• The headline figure is a sales-weighted average of the last four quarterly medians, not a median of individual sales, because one quiet quarter in a single suburb can move a quarterly median by more than the market did. The chart below plots each quarter as published.
• Change over time reflects what sold in each period, not the value of any one home: a run of large or small homes moves it.
• Periods with fewer than 5 recorded sales are excluded.

Schools in O'Halloran Hill

The only school in O'Halloran Hill sits at the 74th percentile nationally on ACARA's socio-educational index.

• ICSEA is ACARA's socio-educational index (average 1000). It describes the family backgrounds of the students enrolled, NOT how well a school teaches: a lower ICSEA means a less advantaged intake, not a worse school.
• Percentiles are ACARA's own national ranking, so the Australia bar is a published figure rather than our arithmetic. Each area shows the median of the mainstream schools sitting inside it; special schools are listed in the table but excluded from the medians.
• Public school intake zones are not published in our dataset for this state, so confirm catchments with the school.
