Australia's rich neotectonic record provides an opportunity to understand the characteristics of intraplate deformation, both at the scale of a single 'active' fault and at the scale of the entire continent. Over the last decade our knowledge of Australian intraplate faults has advanced significantly (e.g. Crone et al., 1997, 2003; Clark & McCue, 2003). Herein, six preliminary seismicity source zones spanning continental Australia, and based upon neotectonics data, are proposed. Each source zone contains active faults that share common recurrence and behavioural characteristics, in a similar way that source zones are defined using the historic record of seismicity. The power of this domain approach lies in the ability to extrapolate characteristic behaviours from well-characterised faults (few) to faults about which little is known (many). This data, and conceptual and numerical models describing the nature of the seismicity in each source zone, has the potential to significantly enhance our understanding of seismic hazard in Australia at a time scale more representative than the snapshot provided by the historic record of seismicity.
