A comprehensive correlation chart of the Tertiary rocks of Australia, New Zealand, and Papua New Guinea is presented including maximum known thicknesses of the formations. The most complete sequences occur in New Zealand. In Australia, rocks of Paleocene to Pliocene age occur in the Gippsland Basin of Victoria and the Otway and Murray Basins of Victoria and South Australia. Significant planktonic foraminifera from the Paleocene Globorotalia chapmani and G. Pseudomenardii to the entry of Orbulina suturalis and O. Universe in the Miocene are shown on a range chart. Tertiary rocks of eastern Australia are predominantly of non-marine or volcanic origin. Few are more accurately dated than of early or late Tertiary age. Non-marine sediments in South Australia and Victoria have been dated on palynological evidence. A tabulation of the formations containing land mammals is given.
