NSW DPI Spatial Data

OISAS Explorer

Browse NSW Priority Oyster Aquaculture Areas (POAA) designated under the Oyster Industry Sustainable Aquaculture Strategy (OISAS). These areas map suitable, high-value sites for oyster farming — they include both leased and non-leased zones.

Note: POAA areas are not farm leases. Individual farm lease boundaries are not publicly available. Available-for-tender lease parcels are published separately via the DPI Fisheries Portal.
