Victorian Submarine Dives
Are Submarines your passion? Victoria has an amazing fleet of four World War One ‘J’ class submarine wreck dive sites which attract divers from around the world. Most of which are in great condition.
J1 or New Deep Sub
Depth: 38 metres
Diverswho were searching for the J4 with their echo sounder set on the wrongscale discovered this Submarine shortly after the J4. Also known as the”New Deep Sub” or the “Winged Sub”, she sits almost on her keel on thesandy bottom. Due to the fine sand in the area, she is prone tosilting. The J1 runs east-west, with her bow facing east. She pointstoward the surface and divers can actually swim under this section.Penetration is possible although very hazardous. Fine silt and tightdoorways add to the danger. Again, guide lines and good torches areneeded and twin independent or manifold scuba cylinders are highlyrecommended for this dive.
Depth: 39 metres
Thisis the deepest of all the J Class Submarines, lying in 39metres ofwater. She is commonly referred to as the “Broken Sub”. She lies on herkeel and is broken in two places and the section behind her conningtower has collapsed, making it the most hazardous of all the J ClassSubmarines to dive. She is subject to fine silting and penetration isnot recommended. The J2 supports prolific fish life and masses ofbrilliantly coloured benthic invertebrates. Due to her location, whichis subject to shipping traffic, she is rarely dived.
Depth: 6 metres
Actuallysitting on top of an old timber wreck called the SF Hersey, the J3 isin very shallow water. Most of the top deck lies above water and is aninteresting snorkel. Underwater, the old timbers of the SF Hersey inconjunction with the bow and stern of the submarine make for anexcellent dive or snorkel. This site is subject to strong currents, andis subsequently dived on slack water only. For a taste of wreck diving,the J3 is a fantastic appetizer.
Depth: 26 metres
ThisSubmarine was discovered in 1984. Brass fittings and other artifactsgives divers a chance to see what it was like to be a sub-mariner. TheJ4 lies on her keel running north-south. Her bow section, which hasbroken away from the main body, lies facing south, while her sternfaces north.
The broken bow section of the submarine contains fourtorpedo tubes, which can be easily seen by using a torch andpositioning yourself between the bow and the main body. This is themost popular of the J Class Submarines due to its relatively shallowdepth, which enables good bottom times. This site is frequently used asa training ground for those on Wreck Diver courses.
J5 or Intact Sub
Depth: 36 metres
Thisunbroken submarine sits on her keel and leans slightly on her starboardside and runs east-west. Her bow faces east while her stern west.Penetration is possible however the stern section and the bow, whichcontains the torpedo tubes, is very tight and silting is a problem -reels and torches are highly recommended. On the stern of the J5,divers can admire the large rudder and drive shafts. Swimming throughthe rudder is easy. This is one of the most photographed of thesubmarines due to the yellow Zoanthids on the conning tower. To diveand or penetrate the J5, the proper certifications are required to beshown, and the use of twin independent or manifold scuba cylinders ishighly recommended.
