A correlation chart for the Triassic System in Australia is presented. The base of the System in Australia is taken as the earliest occurrence of the Lunatisporites pellucidus Assemblage Zone in a section of the Rewan Formation in the Bowen Basin, Queensland, and the base of the Jurassic System as the occurrence of Ceratosporites helidonensis with ClassopoWs and Retitriletes austroclavatitides in the Upper Woogaroo Subgroup in a section near Ipswich in the Moreton Basin. Correlations within Australia are based predominantly on microfioral evidence with supporting evidence from fossil vertebrates and, to a minor degree, on macrofiora. Correlation of Australian units with those in other continents depends on ammonites, bivalves, conodonts, vertebrates, and microfiora in Lower Triassic units; and on vertebrates and microfiora in higher units. A cross-indexed bibliography on the Triassic System in Australia covering 21 years to the end of 1973 is also provided.
