The National groundwater dataset is derived from multiple inputs aggregated together to provide a national coverage for all of Australia.

The dataset provides a nationally consistent set of groundwater boundaries and properties including aquifer boundaries, geometry, salinity, yield and hydraulic conductivity. 

The National groundwater bores is a national dataset aggregated from numerous inputs to produce a consistent coverage over Australia for groundwater bores.

The groundwater bores (including monitoring, irrigation and commercial bores) and associated lithology, construction and hydrostratigraphy logs. The National Aquifer Framework has been used to standardise the hydrogeological unit terminology for this dataset.

The Continental Shelf is the area of the seabed and subsoil which extends beyond the territorial sea to a distance of 200M from the territorial sea baseline and beyond that distance to the outer edge of the continental margin as defined in Article 76 of the Convention. The continental shelf is largely coextensive with the exclusive economic zone within 200M from the territorial sea baselines (there are certain areas between Australia and Indonesia and Australia and Papua New Guinea where they are not coextensive).

Coastal Waters is a belt of water between the limits of the Australian States and the Northern Territory and a line 3M seaward of the territorial sea baseline*. Jurisdiction over the water column and the subjacent seabed is vested in the adjacent State or Territory as if the area formed part of that State or Territory. This, and other arrangements for the management of offshore resources such as fisheries and petroleum, are defined by the Offshore Constitutional Settlement (OCS).
