Where this data comes from
Every source used by the public product, with what it covers and the licence that controls reuse. The formal rights table is on method & licences.

The sales data is not openly licensed, and that matters. The NSW Valuer General publishes bulk Property Sales Information under Creative Commons BY-NC-ND 4.0 — attribution, non-commercial use only, and no derivative works. That is materially narrower than the CC-BY terms carried by the planning, heritage, Census and company datasets on this page. This site previously described it as simply “Creative Commons”, which understated the restriction; that was wrong and is corrected here.
What is not here, and why
- Planning applications outside NSW. The approved application-level source currently covers NSW only. National comparisons use ABS building approvals on consistent definitions.
- Properties currently for sale. This site carries none. Live listings belong to agents and the portals they pay, not to any public register, and there is no open-data source for them.
- Applicant, owner, architect or developer identity. The NSW planning API has no such field. A project cannot be joined to a person or company from this source, and the site does not infer one.
- Company directors and shareholders. ASIC's free dataset carries company identity and status only. Officers are not published free.
- Gated or scraped market data. No listing portal, title service or other gated property source is scraped. Possession in private R2 is not treated as publication permission.
