The Sydney Basin extends for 380 km along the east coast of New South Wales south of latitude 32°S, and has an onshore area of about 36 000 km2 . About 4800 m of Permian and Triassic sedimentary rocks are preserved in the basin which lies between the New England and Lachlan Fold Belts. The study of the Sydney Basin by the Sedimentary Basins Study Group of the Petroleum Exploration Branch of the Australian Bureau of Mineral Resources was undertaken in co-operation with the New South Wales Department of Mines, who prepared a 1:500 000 geological map (PI. 1). The study has required constant exchange of ideas and information with petroleum exploration companies and the Department of Mines. In addition to the authors of this Bulletin the following members of the Sedimentary Basins Study Group since late 1966 have contributed to the study: D. J. Forman, M. A. Reynolds, K. G. Smith, R. Bryan, A. R. Jensen, P. J. Alcock, P. J. Hawkins, R. B. P. Pitt, S. Ozimic, J. I. Raine, K. Rixon, and B. G. West.
