Three minutes later the Allied ship hit Mikuma, killing six and wounding eleven men. With Perth down to firing practice rounds, Harukaze and Hatakaze closed in to before firing eleven torpedoes between them during 23:56–23:58. Two minutes later the destroyers and fired nine apiece at and Natori contributed four more at . About this time, a near-miss damaged the propeller of the Japanese destroyer , which was escorting the heavy cruisers. At 00:05 five of Mogamis torpedoes that had missed Perth struck and sank four transports and blew a minesweeper in half. About this time, Waller ordered his ship to try to force a way through to the Sunda Strait. Just as Perth settled on her new heading, she was hit by a torpedo in the forward engine room, probably from Harukaze. A second torpedo hit two minutes later that punched a hole in the hull near the bridge and two others followed shortly after, probably from Shirakumo and Mirakumo. Waller gave the order to abandon ship after the second torpedo impact. After some further close-range fire from the destroyers, Perth capsized to port and sank at 00:25 on 1 March 1942, with 353 killed: 342 RAN (including Waller), 5 Royal Navy, 3 Royal Australian Air Force, and 3 civilian canteen workers. Houston was torpedoed and sank about 20 minutes later. Of the 328 survivors, 5 died after reaching shore, while the rest became prisoners of war; 106 died during their internment: 105 naval and 1 RAAF, including 38 killed by Allied attacks on Japanese "hell ships". The surviving 218 were repatriated after the war. Unauthorised salvage The wreck was discovered by David Burchell in 1967; at the time, the ship was reasonably intact, lying on its side at a depth of about . In late 2013, divers found that the wreck of Perth was being stripped by unauthorised Indonesian marine salvagers. Reports in September indicated that crane-equipped barges had stripped off most of the wreck's superstructure, forward turrets, and forward decking, and that explosives had been used to break the ship up for easier recovery. These actions compromised the structural integrity of the wreck site, and have potentially exposed live munitions and oil tanks. Perths wreck is not protected as a war grave, either through the UNESCO Convention on the Protection of the Underwater Cultural Heritage (Australia and Indonesia are not signatories to the treaty) or through legislation in
