NSW planning data on PlotDetect

Structured datasets sourced from NSW Government systems and legislative instruments. All data is surfaced through the pages linked below — we do not offer bulk downloads, because regulatory data changes frequently and downloaded files become stale.

Why no bulk downloads?

NSW planning instruments (LEPs, DCPs, SEPPs) are amended regularly. Downloaded CSV or JSON files become stale the moment an instrument is updated. The pages above are revalidated daily so they reflect the current state of the data. If you need programmatic access for a specific use case, get in touch.
