crime index: 20 — below sydney average · trains ~every 10 min at peak
Where every number comes from
- Fair value: AI PropertyEye price model 2026-08-11-v5 — trained on 146,492 published auction sales; configuration-level (suburb × type × beds), not an appraisal of this exact home
- Comps: published Domain auction results for Gymea — suburb × configuration matches, not hyper-matched to this address
- Risk flags: suburb-level overlays (BOCSAR crime, flood/bushfire intel, aircraft bands, GTFS transit) — NOT a per-parcel assessment
Rent evidence — asking vs transacted, Gymea · postcode 2227
$1275–$1780/wk is what 5-bed houses in 2227 actually transact for (middle half of 10 bonds lodged, last 12 mo · median $1525/wk — NSW Fair Trading, CC BY).
2019Q1 → 2026Q2: $695 → $1015/wk · +10% over the last 12 months (latest four quarters averaged against the previous four) — quarterly new-tenancy medians for houses in 2227, all bedroom counts pooled.
Asking rents are what agents hope for; bond figures are what tenants actually signed at (NSW Fair Trading bond lodgements, CC BY). No yield % is derived here: each rent above is a different grain from this home's price, and a ratio of two grains reads as precision it doesn't have. New-tenancy rents run hotter than sitting rents. Not financial advice.

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. Two entries on one date are usually a single transaction recorded across parts. © State of New South Wales (Valuation NSW).
Planning & zoning — R3 Medium Density Residential
Townhouses, villas and low-rise units permitted — expect gradual medium-density infill.
Registered lots in Gymea run 300–700 m² (middle 80% of 24 registered parcels). This one is 572 m² — inside that range.
Whether a block this size can be subdivided or redeveloped is a separate question: minimum lot size, setbacks and the council's DCP controls decide it, and this page doesn't check them. One point per registered parcel, so a tower's parent lot counts once — not once per unit. Confirm the parcel and its controls with the council before you inspect.
Zone R3 (Medium Density Residential) under the SUTHERLAND SHIRE LEP, as recorded against this property in the NSW Valuer General's valuation record — a guide, not a parcel-level legal check. Confirm the exact lot at the NSW Planning Portal.

Where these applications come unstuck
The refusal rate above says how strict the council is. This says which part of a plan is exposed — measured across all 192,284 NSW development applications, not just this council. Each is an association: plenty of applications carrying these elements are approved, and nothing here is a verdict on a proposal you haven't made yet.
- Alterations & additions — a new vehicle crossing cut into the front boundary (refused 7.27% vs 2.59% for this kind of work generally — 2.8×, on 220 applications); excavation or a new lower level (refused 6.71% vs 2.54% for this kind of work generally — 2.64×, on 611 applications)
- Off-street parking — a new vehicle crossing cut into the front boundary (refused 8.45% vs 2.42% for this kind of work generally — 3.49×, on 284 applications)
- Pool, deck or fence — excavation or a new lower level (refused 6.22% vs 1.61% for this kind of work generally — 3.88×, on 659 applications); full demolition and rebuild (refused 4.97% vs 1.6% for this kind of work generally — 3.12×, on 965 applications)
- Knock down & rebuild — excavation or a new lower level (refused 25.78% vs 9.36% for this kind of work generally — 2.75×, on 256 applications); full demolition and rebuild (refused 19.91% vs 10.46% for this kind of work generally — 1.9×, on 221 applications)
Determinations lodged on the NSW Planning Portal up to Nov 2023 — the published dataset stops there, so this is a record of how the council has behaved, not a forecast and not a statement about any particular application. Rates cover development applications only; modifications and reviews of an earlier decision are excluded. A rate is shown only where at least 30 applications were decided — below that the counts are given instead, because a percentage from a handful of decisions is not a fact about a council. "Approved with conditions" is a consent, not a refusal, and is never counted as one.
