Later research using multibeam bathymetry data available from Geoscience Australia and the GMRT (Global Multi-Resolution Topography) Synthesis, infilled with data derived from the GEBCO_2014 global bathymetry dataset, suggested that the deepest point in the fracture zone would be at

Australian exclusive economic zone. Professor Jamieson's team deployed baited landers beyond 6,000 m (20,000 ft) water depth aiming to document the biodiversity and geology of the region.
