In doing some research on the minesweepers, I came across the story of the Abraham Crijnssen, a Dutch minsweeper:

” HNLMS Abraham Crijnssen was stationed in the Dutch East Indies when WW II began. After the destruction of the Allied Fleet by the Japanese during the Battle of the Java Sea in February 1942, Crijnssen‘s captain was ordered to escape with his ship to Australia. Covered with tree branches, the minesweeper crossed the Japanese naval lines camouflaged as a tropical island.”

The ship is still afloat and docked in the Netherlands. You can read more about the ship here (Link).

Looking at the pictures of the Crijnssen, it looks like a more modern ship than the Partridge, but about the same dimensions.
