The Namoi subregion is part of the Northern Inland Catchments bioregion (Figure 3). The Northern Inland Catchments bioregion is located west of the Great Dividing Range in eastern Australia. It includes parts of the northern Murray–Darling Basin in northern New South Wales and southern Queensland. Parts of the northern Murray–Darling Basin that are not underlain by coal are not included. The bioregion adjoins the Clarence‑Moreton bioregion in the north-east, and the Northern Sydney Basin bioregion in the south. It covers an area of about 248,000 km2.
The Namoi subregion boundary is the same as the Namoi Catchment Management Authority boundary over the extent of the coal-bearing geological basins. The Namoi subregion does not extend further east than this, so covers a smaller area than both the Namoi Catchment Management Authority and the Namoi river basin.
