About HMAS J5 Submarine

HMAS J5 was the last of the J-class submarines to be scuttled, in 1926 off the Mornington Peninsula coast in Bass Strait. She lies on a sand bottom in approximately 30 metres of water, broadly intact along the pressure-hull line with conning tower and propeller assembly recognisable. The deepest and most exposed of the J-class wrecks, requiring Advanced certification plus deep-dive and Bass Strait experience. Soft coral and sponge growth densely covers the metalwork. Protected under the Historic Shipwrecks Act 1976.
