This is a list of regions of Australia that are not Australian states or territories. The most commonly known regionalisation is the governmental division of the state into regions for economic development purposes.
Others regionalisations include those made for purposes of land management, such as agriculture or conservation; information gathering, such as statistical or meteorological. Although most regionalisations were defined for specific purposes and give specific boundaries, many regions will have similar names and extents across different regionalisations. As a result, the names and boundaries of regions can vary and may overlap in popular places.
Not all the regions in this list have official status as an economic or administrative region.
