This paper reports a sighting of two Common Dolphins Delphinus delphis off Blairgowrie in Port Phillip Bay, Victoria. Once the dolphins were sighted they were continuously observed using an instanteous sampling technique to document focal group activity. The Common Dolphins were continuously observed for a total of four hours. The preferred shore distance of these Common Dolphins was 150 m in a water depth of 10-15 m. The most common behaviour observed was feeding behaviour (87.5%) followed by social behaviour (10.4%) and travel behaviour (2.1%). Two whistles and one echolocation pulse were recorded during the observation period.
