Whale watchers in southwest Western Australia reported humpback whale numbers 60% below normal in late June.
Large numbers of rarely seen albatrosses and petrels appeared off Australia's east coast, thousands of kilometers from their usual foraging grounds.
A marine heatwave has affected waters around Australia's Heard Island and McDonald Islands since February.
The southern Tasman Sea has endured a marine heatwave since at least April.
The sightings raise questions about altered conditions in the Southern Ocean, possibly linked to marine heatwaves.
