Where to dive in Australia in August
Humpback swims at Ningaloo, mantas peak at Lady Elliot, and Port Jackson sharks and cuttlefish breed in the south.
August brings the humpback whale swim season to Ningaloo and the tail of the manta peak at Lady Elliot. The reef's trade winds can blow hard for days, so build slack into a Queensland trip. In the south the Port Jackson sharks are aggregating to breed, giant cuttlefish are displaying on the Victorian and Tasmanian reefs, and the water is at its coldest (11–13 °C) but often flat and clear on the east-facing coasts.
