Bioregions referenced in determinations
In determining the bioregions where an ecological community occurs, the Committee uses the Biogeographic regionalisation of Australia. The Committee’s determinations indicate which version has been referenced for a particular ecological community.
As a guide, the Committee has used the following versions.
Version 4 - Determinations made before March 2013
The Committee used Thackway R, Cresswell ID (1995) An interim biogeographic regionalisation for Australia: a framework for setting priorities in the National Reserve System Cooperative Program. (Version 4.0. ANCA: Canberra).

Version 7 - Determinations made since March 2013
The Committee currently uses SEWPaC (2012) Interim Biogeographic Regionalisation for Australia, Version 7. Department of Sustainability, Environment, Water, Population and Communities.
