HMAS Australia (I84/D84/C01) was a County-class heavy cruiser of the Royal Australian Navy (RAN). One of two Kent-subclass ships ordered for the RAN in 1924, Australia was laid down in Scotland in 1925, and entered service in 1928. Apart from an exchange deployment to the Mediterranean from 1934 to 1936, during which she became involved in the planned British response to the Abyssinia Crisis, Australia operated in local and South-West Pacific waters until World War II began.
On 25 September, Australia and HMS Devonshire shelled French ships anchored at Dakar. They damaged a destroyer and several cruisers before Australia was hit by two 6-inch shells and her Walrus was shot down with all aboard killed, after which the two ships withdrew.
