Carronade Island lies off the northern (Kimberley) coast of Western Australia (Coordinates: ). The small island in Napier Broome Bay owes its name to two swivel guns found there in 1916, mistakenly described as carronades at the time.
In July 1916, the Royal Australian Navy cruiser HMAS Encounter entered Napier Broome Bay on Australia’s north west coast. On a small island in the bay, a party from the ship found two bronze cannons, protruding from the ground and placed about six feet apart.
The two bronze guns, of different bore and design but both about one metre in length, were removed to Garden Island Naval dockyard.  They were initially interpreted as "part of the armament of a Spanish or Portuguese caravel," a conclusion also made by writer Kenneth McIntyre in 1977. McIntyre cited the guns as evidence to advance his theory of Portuguese discovery of Australia and described the cannons as "the most tangible extant link with the first European discovery of Australia."
A detailed report by Jeremy Green of the Western Australian Museum has identified both of the guns as swivel guns. Using metallurgical examination, including X-ray and chemical analysis, the guns have been identified as of late 18th century South East Asian origin and likely to have arrived through Makassan contact with Australia. The claim that the more decorated gun displays a Portuguese "rose and crown" is incorrect.
