Population figures are projections (DPHI 2024 NSW Population Projections (2022–2041 series)) for the ABS statistical area, not a guarantee. Project lists: School Infrastructure NSW and Health Infrastructure / Homes NSW public project pages (snapshot 2026-07-26); a "Planning" status is not a commitment — projects change, slip and get cancelled. The paid address report adds state-budget projects and growth-area checks around the specific address.

What we check at the address level

Suburb averages can't tell you about one specific property. The full PropertyFlags report checks the address itself against official government layers — flood and bushfire mapping, zoning and height controls, development applications nearby, EPA contamination records, defect orders, aircraft and road noise, school catchments and more — and turns them into red, yellow and green flags with the questions to ask the agent.
