The destroyer HMAS NEPAL, (CMDR F.B. Morris, RAN), was commissioned at Woolston, England.
A Japanese Navy seaplane from the submarine I-21, flew over Sydney and Newcastle, at night, to conduct reconnaissance in preparation for the midget submarine attack against Sydney Harbour which took place two nights later. The pilot, LEUT Susomo, reported he flew so low over Sydney Harbour that he was able to identify welding sparks from work being conducted at Cockatoo Island Dockyard. On return to the submarine, the aircraft crashed in the choppy seas, and sank, but Susomo swam to the submarine to make his report.
HMAS KURU, (auxiliary patrol vessel), returned to Darwin after making her first re-supply run to Australian troops still fighting a guerrilla campaign in Timor.
