The submarine Kenn Plateau, with an area of about 140 000 km2, lies some 400 km east of central Queensland beyond the Marion Plateau. It is one of several thinned continental fragments east of Australia that were once part of Australia, and it origin

The Albany canyons complex off southwest Australia extends 700 km from Cape Leeuwin to east of Esperance. The submarine canyons head on the uppermost continental slope and extend from there up to 90 km offshore, to the lowermost slope and onto the ab

The Murray canyons are a group of deeply incised submarine canyons on a steep 400 km section of the continental slope off Kangaroo Island, South Australia. Some of the canyons are amongst the largest on Earth. The canyons, some 80 km long, descend fr

Digital echo sounding, SeaBeam swath bathymetry data and sediment cores were collected on the continental slope (1500–3700 m water depth) off southeastern Tasmania in order to study sedimentary processes in the vicinity of an ocean disposal site. T

The continental margin facing the southern Tasman Sea off southeastern Australia is of high petroleum and geological significance because it contains Australia's richest oil province, the Gippsland Basin. Exploration activity in the region has concen

The Sorell and southernmost Otway Basins, off west Tasmania, cover an area of 100 000 km2. At least 6 km of Cretaceous‐Tertiary section is present in places and more than 50% of the region has a sediment thickness greater than 2 km. Free oil traces

The 50 000 km2 East Tasman Plateau has been regarded as a continental block on the basis of geophysical data, but this study is the first to prove its continental nature directly by sampling of basement rocks. Continental rocks recovered from four st

The South Tasman Rise is a continental fragment of 200 000 km2 lying south of Tasmania and surrounded on three sides by Late Cretaceous and Palaeogene oceanic crust, which assumed its present configuration in the Palaeogene. The western side of the r

The 1994 Tasmante swath-mapping and reflection seismic cruise covered 200 000 km2 of sea floor south and west of Tasmania. The survey provided a wealth of morphological, structural and sedimentological information, in an area of critical importance i

Considerable areas of Australia's offshore region were mapped recently using modern multibeam seafloor swath-mapping systems such as Simrad EM12D and Sea Beam 2000. The new and advanced technology built into these systems has led to the acquisition o
