1940: The first casualty, HMAS GOORANGAI in Victorian waters - Photo AWM.
4992. As has already been well told on the Photostream, the 223 grt auxiliary minesweeper HMAS GOORANGAI was the RAN'S first ship casualty in WWII - and its first surface ship loss in wartime - when she was run down at the entrance to Port Phillip Bay by the 10,000 ton troopship MV DUNTROON on the night of November 20, 1940.
All 24 men aboard GOORANGAI were lost, and only five bodies ever recovered.
We told the story way back at pic NO. 128, here:
A Maritime Archeology Association of Victoria [MAAV] report on the loss of the GOORANGAI:
