A sequence of Campanian dinoflagellates recorded from the exploration well Pisces-1 in the Gippsland Basin is compared with material recovered from two dredge samples from the continental slope of the same region. The Campanian sequence from Pisces-1 is the most complete so far examined from the basin, and it provides a reference for local correlations. Assemblages studied are assigned to theIsabelidinium korojonenseZone (Helbyet al., 1987) and a new biounit named theSatyrodinium haumurienseZone. Five new species are described:Canningia bassensissp. nov.,Gillinia pyriformissp. nov.,Senoniasphaera edenensissp. nov.,Chatangiella packhamiisp. nov., andIsabelidinium greenensesp. nov.
