Interpretation of Ion seismic and regional gravity data defined the deep basin geometry down to the Moho and the GA seismic data were reinterpreted to indicate palaeobathymetry in the now deep-water parts of the basin and the likely facies. A new, fully balanced, decompacted and restored regional section across the delta shows the deposition and deformation through time with emphasis on the erosional events and water depths. Significantly, the sectiosn are restored to paleo-water depth at all times, which significantly changes the basin geometry, the interpretation of facies and migration directions. In addition, a forward model in MoveTM shows how the gravitational collapse structures formed allowing the early delta to propagate. Combining all this information has allowed a model to be developed for the basin evolution which can predict the timing and size of structural traps, the timing of maximum burial and hydrocarbon charge and the direction of charge (landward vs seaward). The final step is full Underworld finite element modelling of the basin to test models of Australia- Antarctica breakup and to predict temperature through time and hence hydrocarbon charge.
