Thornleigh · Sydney NSW

Price model — what the model says a typical home here achieves at auction

Modelled from 146,492 Australian auction sales (2021–2026). Sydney cells run on the base model (suburb prior + configuration + time) without the Sydney-only land/school/transport features — ranges are honest about the wider uncertainty. Estimates from comparable auction results — not valuations or financial advice.

Buildings in Thornleigh — full dossiers: every sale, turnover, orders, what units rent for

The 20 most-transacted of 21 Thornleigh buildings with dossiers — the rest are reachable from these pages and the sitemap. Sales counts and resale records from NSW Valuer General bulk data (CC-BY); lot counts from the NSW Strata Hub register. Each dossier also states what public records cannot tell you.

Recent sold auction results in Thornleigh from the price model's training set (published Domain results). A sample, not every sale.

What Thornleigh actually sold for — published auction results, quarter by quarter

Quarterly medians of real published auction results (sold outcomes only). Historical results — not a prediction, valuation or financial advice.

All settled sales — every recorded sale, not just auctions

Last 12 months: 140 settled sales · median $1,612,500 (middle half $797,250–$1,886,500)

Settled-sale records from the NSW Valuer General's Property Sales Information. Dates are contract (exchange) dates; sales appear only once lodged, so the most recent months are incomplete and revise upward — never read the latest month as final. Residential sales of all methods — private treaty and auction. © State of New South Wales (Valuation NSW).

What Thornleigh homes rent for — real bonds lodged, postcode 2120

2019Q1 → 2026Q2: $500 → $730/wk median new-tenancy rent in 2120, all dwellings pooled · +6% over the last 12 months (latest four quarters averaged against the previous four).

Every figure is from NSW Fair Trading rental bond lodgements (CC BY) — rents tenants actually signed at, not advertised asks. Postcode is the finest geography the source publishes, and a postcode may span more than one suburb. Middle half = 25th–75th percentile. New-tenancy rents run hotter than sitting rents. Not financial advice.

Crime — recorded key offences (BOCSAR)

Index 22 — below the Sydney average (50 = average) · band low

BOCSAR recorded key offences per resident at POSTCODE level (2120) — a postcode can span neighbouring suburbs. Rates are per RESIDENT — visitor-heavy precincts read high. Source: NSW Bureau of Crime Statistics and Research (CC BY 4.0).

Schools — density, catchment and community profile

5 primary schools within 2km · nearest school ~0.66km · 2 selective within 5km · ICSEA 1140

Catchment (suburb-centre approximation): Thornleigh WPS · Pennant Hls HS — a boundary address can differ; verify yours at NSW School Finder.

ICSEA is the socio-educational advantage of a school's community (My School, national average ~1000) — a demographic measure, not a quality or results score. NSW DoE school locations + intake zones, CC BY 4.0.

Development pipeline — what's proposed in Thornleigh, and how far along it is

State-pipeline proposals (pre-DA — the biggest projects start here)

• 206-212 Pennant Hills Road, Thornleigh — 21 storeys, 250 apartments including 5% affordable housing & ground floor retail
  Iris Hotels Thornleigh Property Pty Ltd · Proposed — state-pipeline EOI (pre-DA, may change or lapse)

What this view cannot see

• Council DAs from the NSW Planning Portal open feed, matched within ~150 m of addresses we track — a proximity net, not a complete register.
• Verdicts (approved/refused) come from a dataset frozen in Nov 2023: anything determined after that shows “determined” without a published outcome. Check the application on the NSW Planning Portal for the current decision.
• The largest master-planned sites can proceed as State Significant Development or planning proposals and never appear as council DAs. State-pipeline EOIs shown here are proposals, not applications, and can change or lapse.
• No feed we hold ties a construction certificate to a specific application, so no project row here can honestly read “under construction” — “approved” never means “built”. Suburb-level construction-certificate volume appears in the DA-volume section.

Housing and jobs targets — HORNSBY LGA

Under the NSW Government's 20-year Sydney plan, HORNSBY has a five-year housing target of 5,500 new homes (2024–2029) and a jobs target of 13,100–22,100 additional jobs by 2046.

The housing target is the supply pipeline for the area: the number of new homes the state expects the council to plan capacity for, concentrated around the centres and station areas the Plan nominates. The jobs figure is published as an aspirational range and is not legislated the way housing targets are.

State rezoning pipeline — Hornsby LGA

The Sydney Plan lists 2 state significant rezoning sites in this LGA — land the NSW Government is rezoning (or has rezoned) for additional homes and jobs, alongside council-led supply. Dwelling and jobs figures are preliminary estimates provided by proponents or councils.

• Cherrybrook Precinct (Hornsby, The Hills) — ~10,000 dwellings, ~200 jobs · rezoning completed Aug 2026
• Hornsby TOD Accelerated Precinct — ~6,000 dwellings, ~2,900 jobs · rezoning completed Nov 2024

These are LGA-level sites, not a statement about any individual property; the Plan does not publish site boundaries or coordinates in this appendix.
