AUSTRALIA Swainson 1835

Unmack (2001) created a series of 10 new names (10 provinces divided into 31 regions), nine of which fall under existing names used by Iredale & Whitley (1938). All nine names are synonymised herein. Unmack (2001) gives no reason for his inverted classification of grouping biogeographic regions into provinces (i.e., subregions). Furthermore, Unmack’s “regions”, based on Australian Water Resources Council (AWC 1976) river basins and therefore not biotic, are omitted from this revision. Similarly, we have not included classifications used, for example, by Lake (1971, 1978), Allen (1989) or Allen et al. (2001), which are essentially abiotic drainage classifications from Bauer (1955) and AWC (1976). Unmack’s tenth province (Paleo Pronvince) is also based on abiotic factors, lacking endemic taxa and corresponding largely to the Western Plateau Drainage of AWC (1976).
