ABSTRACT We recorded a diverse cetacean assemblage from systematic aerial surveys in productive upwelling waters off southern Australia in 2002-2013. Surveys recorded 133 sightings of 15 identified cetacean species consisting of 7 mysticete (baleen) whale species, 8 odontocete (toothed) species, and 384 sightings of unidentified dolphins. This is the first assessment of cetacean diversity for the region and we found diversity to be comparable with other productive regions elsewhere. Differential spatial and temporal distributions of mysticete and odontocete species were apparent, and were associated with habitat variables and seasonal migration cycles. The study contributes new information to assist the environmental planning and management of activities in the region, including oil, and gas exploration and production, fishing, shipping, and renewable energy development. © 2015 The Wildlife Society.
