Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of l ...

. The IBRA bioregions informed the delineation of the WWF ecoregions for Australia, and the WWF ecoregions generally follow the same ecoregion boundaries, while often clustering two or more similar bioregions into a larger ecoregion. The ecoregion articles in Wikipedia generally follow the WWF scheme.
The WWF ecoregions are based heavily upon the

WWF freshwater ecoregions
The WWF published Freshwater Ecoregions of the World, a global map of freshwater ecoregions. The WWF team identified ten freshwater ecoregions for Australia and Tasmania. A major habitat type, or biome, was identified for each ecoregion. The four major habitat types present in Australia are tropical and subtropical coastal rivers, temperate coastal rivers, temperate floodplain rivers and wetlands,
and xeric freshwaters and endorheic (closed) basins. The Australian freshwater ecoregions were adapted from the freshwater fish biogeographic provinces identified by Peter Unmack and G.R. Allen, S.H. Midgley, and M. Allen, who were also part of the WWF team. The freshwater fish provinces "were derived through similarity analyses, parsimony analysis, and drainage-based plots of species ranges".
