Palynological examination of eight samples from Bus Swamp 1 Well, Otway Basin, western Victoria, was undertaken. The samples range in age from the upper part of the Cicatricosisporites australiensis Zone of Helby et al. (1987) to the upper part of the Foraminisporis wonthaggiensis Zone, ie. Berriasian to Barremian (Early Cretaceous). Palynological data presented in unpublished reports by Morgan and Burger were examined and correlated with the Australian Mesozoic scheme of Helby et al. (1987). These additional data show the samples analysed from Bus Swamp 1 range in age from Coptospora paradoxa Zone (Middle Albian) through to C. australiensis Zone (Berriasian).
