According to the Federal Department of the Environment, Australian sea lions feed on a wide variety of prey including cephalopods such as squid and octopuses, fish, sharks, rock lobsters and sea birds.

"There is little quantitative information on their diet as only a few hard parts are normally found in the faeces of this species, although the species is known to 'feed' at fishing boats on scraps or by taking fish off lines," the spokesperson said.

"Australian sea lions in Western Australia spend more time foraging compared to those in South Australia due to the less productive conditions of the Leuwin Current."
