Remoteness Areas divide Australia and the States and Territories into 5 classes of remoteness on the basis of relative access to services. Remoteness Areas are based on the Accessibility and Remoteness Index of Australia (ARIA+), produced by the Hugo Centre for Population and Migration Studies. Remoteness Areas are aggregates of SA1s that are grouped together based on their average ARIA+ score.
The Australian Statistical Geography Standard (ASGS) Edition 3 Remoteness Structure will be released in early 2023.
The most current version of the Remoteness Structure is from ASGS 2016 - 1270.0.55.005 - Australian Statistical Geography Standard (ASGS): Volume 5 - Remoteness Structure, July 2016.
