The Interim Biogeographic Regionalisation for Australia (IBRA) is a
biogeographic regionalisation of Australia developed by the Australian government's
Department of Sustainability, Environment, Water, Population, and Communities. It was developed for use as a planning tool, for example for the establishment of a
national reserve system. The first version of IBRA was developed in 1993–94 and published in 1995.

. Based on this system, the world is also split into 14
terrestrial habitats, of which eight are shared by Australia. The Australian land mass is divided into 89
bioregions and 419 subregions. Each region is a land area made up of a group of interacting ecosystems that are repeated in similar form across the landscape.
IBRA is updated periodically based on new data, mapping improvements, and review of the existing scheme. The most recent version is IBRA7, developed during 2012, which replaced IBRA6.1.
