Osterley ^{NSW 2324}

Osterley's house market is moving lower: the median sale price reached $1.25 million in the December 2025 quarter, roughly 24% below where it sat a year earlier. That said, only three sales settled in the quarter, so the median is a noisy signal — treat it as a direction rather than a level. Zoom out: prices have climbed roughly 91% over the past decade — 7.4% per year on average.

The three add up to the change above. These are council-wide figures from the ABS, not figures for this locality alone — this locality's own population is in the census section above.

Households face an average residential rates bill of $1,359 a year through Port Stephens based on 2024 figures.

Zoning sets what may be built, not what is there today. A single address can sit in a different zone to the locality around it — the property page shows the zone for one address.

In the year to August 2026, 495 new dwellings were approved across Port Stephens. That mix is 294 houses and 201 units. Approvals are down 72.1% on the same period a year earlier.

Aboriginal Land Council

Aboriginal land in this area is administered by the Worimi Local Aboriginal Land Council.

Local Aboriginal Land Councils are statutory bodies under the Aboriginal Land Rights Act 1983, responsible for land claims and land management for their members. Their boundaries are administrative and are not a statement of whose Country this is. NSW does not publish a register of Aboriginal parties by area — they are registered for each project.

PM2.5 averaged 6.3 µg/m³ in 2025 — below Australia's NEPM annual standard (8 µg/m³), slightly above the stricter WHO guideline (5 µg/m³). 1 day exceeded the daily threshold of 25 µg/m³.

PM10 averaged 17.5 µg/m³ · NO₂ averaged 0.72 pphm. Days over the limit in 2025: PM10 1 · NO₂ 0 · ozone 0.

Elevation is the ground at the locality centre, from Geoscience Australia's National Digital Elevation Model. Approximate — it reads high in dense built-up areas. It is a measure of height above sea level and not an indicator of flood risk, which depends on height above nearby waterways.

Results are per division — federal electoral boundaries are redrawn periodically, so the history reflects this division's past, not necessarily the exact locality's voters across time.

Results are per district. Districts were last redrawn in 2021, so results from before then describe the district of that name, not necessarily this locality's voters. Results: © State of New South Wales through the NSW Electoral Commission, CC BY 4.0, adapted.
