An inshore regionalisation of Australian waters derived from biological and physical data, including the distribution of demersal fishes, marine plants and invertebrates, sea floor geomorphology and sediments, and oceanographic data.The meso-scale regionalisation was compiled from information supplied to the Australian Government Department of Climate Change, Energy, the Environment and Water by the relevant State, Northern Territory and Commonwealth marine research and management agencies.The seaward extent for the meso-scale IMCRA coverage is defined by the 200m isobath except where this boundary extends beyond the Australian Exclusive Economic Zone (AEEZ).
