Roads
Get roads data for the entire Australian road network – nationally connected and grounded in authoritative sources.
Geoscape Roads is a digital representation of the road network across Australia – a national view of road centrelines.
It aggregates road networks across the county into a single network. Improved description of road infrastructure delivers consistency in road geometry and attributes across state and territory borders. And connectivity of roads at borders.
Roads are defined and classified at national level, while being grounded in government held road records.
What data is available?
Geoscape Roads contains linear features that describe surfaces that are improved to enable vehicle travel on land. And ferry routes that enable road vehicles to cross bodies of water.
Roads data attributes describe each road’s characteristics.
- Road name and alias
- Road hierarchy, for example, national or state highway, arterial road or local road
- National and state route numbers
- Road type, for example, road, roundabout, tunnel or bridge
- Number of lanes
- One-way or two-way traffic direction
- Public or private road access
- Road surface – sealed or unsealed
- Minimum vehicle type required, for example, 2WD
- Coordinates of latitude and longitude.
How can I get Roads data?
Roads data is available as a national dataset representing the road network across Australia. It’s also available as individual datasets for each Australian state and territory.
Full Dataset
- Whole-of-Australia data, when you just need it all.
- Formats:
- ESRI Shapefile
- MapInfo TAB

How is Geoscape Roads created?
Roads data is sourced and processed continuously, with an update to the national roads product released each month.
Road centrelines are primarily sourced from state and territory governments. They form the basis of the roads network. The connectivity of roads at state and territory borders is manually reviewed against licensed imagery and other reference data and corrected to maintain national roads connectivity.
The spatial accuracy of roads data reflects that of the source. It’s accurate to +/- 2 metres in urban areas and +/- 10 metres in rural and remote areas. The data is available referencing GDA94 and GDA2020 datums.
How can you use Roads data?
As a single, national representation of Australian roads with detailed attribution, Geoscape Roads enables visualisation, analysis and transport planning at both a national and local scale.
Transport planning
Enhance your transport analytics and cross border route planning. As a digital representation of a connected road network, Geoscape Roads is a base for analysis and decision making.
Traffic modelling
Use the national, authoritative roads data in Geoscape Roads to model traffic flow and congestion. Analyse and predict the impact of new infrastructure developments or major events.
Mapping
Represent Australia’s roads on a map or other method of visual display. Use the road geometry, name labels, route numbers and consistent classifications in Geoscape Roads for your visualisation.
