In 2005 Geoscience Australia and the National Oceans Office undertook a joint project to produce a consistent, high-quality 9 arc second (0.0025° or ~250m at the equator) bathymetric grid for Australian waters. \n\nThe 2009 bathymetric grid of Australia has been produced to include new datasets available, and to provide a grid that fixes issues identified in the previous version. The revised grid has the same extents as its 2005 counterpart, including the Australian water column jurisdiction lying between 92° E and 172° E, and 8° S and 60° S. The waters adjacent to the continent of Australia and Tasmania are included, as are areas surrounding Macquarie Island, and the Australian Territories of Norfolk Island, Christmas Island, and Cocos (Keeling) Islands. The area selected does not include Australia's marine jurisdiction off of the Territory of Heard and McDonald Islands and the Australian Antarctic Territory.\n\nThe Australian 9" DEM was used as the topographic dataset for the Australian Continent and surrounding islands. The 250m New Zealand DEM was sourced from Geographx (NZ) Ltd (2008) in Ascii format, non-projected, NZ Mercator datum. The 90m Shuttle Radar Topography Mission (SRTM) DEM was sourced for the southern areas of Papua New Guinea and Indonesia from the CGIAR Consortium for Spatial Information (CIGAR-CSI) in the WGS84 datum in the ASCII format.\n\n© Commonwealth of Australia (Geoscience Australia) 2009.
