Seaton (SA 5023): property prices & suburb profile

Seaton property prices

The typical Seaton house sold for around $1,077,000 in the year to 2026-Q2, +127.7% over 10 years and +85.7% 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.

• SEIFA decile 1 is the lowest tenth of Australian areas on that index and 10 the highest. The four indices measure different things and often disagree, which is why all four are shown: a suburb can rank high on education and occupation while ranking mid on economic resources.

Schools in Seaton

The 2 schools in Seaton sit at the 46th 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.
