What did the Australians do in Ambon?

From stories told by my father I know that Australian soldiers fought in Ambon in 1942. There are also war memorials for their service on the island. Where can I find more information about those Australians?

Digital Collection

The Digital Collection of ‘Farewell to the Indies' contains reports by the Australian Gull Force infantry battalion that was sent to Ambon. Inventory numbers 184 to 217 contain information on the agreements that Australia and the Dutch East Indies made before the war. Inventory numbers 573 and 686 to 706 primarily contain information about the war years and the efforts of the Australian troops in Ambon and Timor.
