Technical diving expedition to the wreck of the I-124 submarine

In World War II Japan and Australia fought for control of the seas north of Australia. The I-124 Japanese submarine was laying mines and hunting ships outside Darwin Harbour when it was engaged by Australian forces. It was attacked and sunk to the seafloor. All 80 submariners perished. Lying 53 metres below the surface, the wreck is highly significant. But the Top End's strong tides, murky waters and the submarine's depth have made it impossible to visit. Until now.
