The only Japanese force to land in Australia during World War II was a reconnaissance party that landed in the Kimberley region of Western Australia on 19 January 1944 to investigate reports that the Allies were building large bases in the region. The party consisted of four Japanese officers on board a small fishing boat. It investigated the York Sound region for a day and a night before returning to Kupang in Timor on 20 January. Upon returning to Japan in February, the junior officer who commanded the party suggested using 200 Japanese prison inmates to launch a guerrilla campaign in Australia. Nothing came of this and the officer was posted to other duties.
