Structure of the southern New South Wales continental margin, south-eastern Australia

High-quality, regional seismic data collected on the continental margin of southern New South Wales indicate that the margin lacks major basin development, consistent with its interpretation as an upper plate margin. The most striking structural feature is a mid-slope graben or half graben which is bounded on its eastern (seaward) side by a westerly-dipping fault system and a basement ridge. The half-graben contains up to 2.2 seconds TWT (~2500 m) of sediment, including syn-rift deposits possibly as old as Late Jurassic. A seaward-thickening wedge of sediment overlies a generally flat basement surface beneath the shelf. This contrasts with large areas of the lower continental slope which are essentially free of sediment. Sediment thicknesses beneath the Tasman Sea abyssal plain reflect basement structure. The greatest thickness occurs next to the foot of the slope where sediment loading has produced flexuring in either oceanic or thinned-continental crust. Overall, the petroleum potential of the margin (excluding the pre-rift Sydney Basin rocks) appears to be low.
