The accurate position of highly stable reference stations across the nation is fundamental to all location-based technologies used in Australia. The resulting outputs of the National Positioning Infrastructure (NPI) Capability and national observations and measurements are the 3D (horizontal and vertical) coordinates of these reference stations maintained by the Commonwealth and States and Territories.

The Land Parcel dataset is a data aggregation sourced from the jurisdictions which depicts national and accurate land and strata based information including parcels representing easements, roads, crossing, rail and water.
Crossings are structures built to facilitate the movement over, under or through another physical feature. In the Transport Theme, crossings include bridges, tunnels, fords, culverts and boardwalks.
There are a number of geodetic observations and measurements performed at the national and local scale that contribute to datum definition, standards and lower positioning uncertainties. They also form part of the fundamental physical infrastructure that contribute to the National Positioning Infrastructure (NPI) Capability.
The national state electoral boundaries is a national coverage derived from the aggregation of the state and territories state electoral boundaries into a single coverage.
National Town Points is an aggregated dataset of the national coverage of all town points for each state and territory.
National Regions is an aggregated dataset of the national coverage of all regional datasets for each state and territory.
The national federal electoral boundaries is a national coverage different federal electoral boundaries into a single coverage.
National Parishes is an aggregated dataset of the national coverage of all parishes for each state and territory.
Australia's future safety, prosperity and sustainability depends on making informed policy and investment decisions that meet the needs of today, and the decades ahead. Digital elevation data which describes Australia's landforms and seabed is crucial for addressing issues relating to the impacts of climate change, disaster management, water security, environmental management, urban planning and infrastructure design.
