Eliza Ramsden - Depth: 21 metres OW
The Eliza Ramsden was a three masted iron barque 45 metres in length built in Clyde, Scotland in 1874. During the night of July 1875, she struck Corsair Rock while leaving the Heads for Newcastle. In an attempt to return to Melbourne, she sank in the South Channel where she sits upright on her keel. Over the years the Ramsden has been blasted to minimize the hazard she created to shipping, but despite all this, she still presents an excellent dive. Her bow, in particular, coming up from 21to 14 metres is the most popular section providing photographers with a wide array of marine life.

SS Coogee - Depth: 34 metres AOW
The Coogee was a bay steamer used in Port Phillip Bay until it was stripped and scuttled in 1927 just outside the Port Phillip Heads. The wreck now lies in 34metres of water and is abundant with marine life and still quite intact.The top of the wreck is in about 26mtrs with the bow and stern sections quite intact but the midsection with the exception of the boilers is quite broken up.

J1 or New Deep Submarine - Depth: 38 metres Deep
Divers who were searching for the J4 with their echo sounder set on the wrong scale 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 the sandy bottom. Due to the fine sand in the area, she is prone to silting. The J1 runs east-west, with her bow facing east. She points toward the surface and divers can actually swim under this section. Penetration is possible although very hazardous. Fine silt and tight doorways add to the danger. Again, guide lines and good torches are needed and twin independent or manifold scuba cylinders are highly recommended for this

J4 or 26m Submarine - Depth: 26 metres AOW
This Submarine was discovered in 1984. The J4 lies on her keel running north-south. Her bow section, which has broken away from the main body contains four torpedo tubes, which can be easily seen by using a torch and positioning yourself between the bow and the main body. Penetration of the wreck is possible via several large openings in the hull. Such penetration should not be taken lightly, as being shallower than the other subs, this wreck is particularly susceptible to surge. However, the surge prevents any silting, and under suitable conditions this makes for one of Melbourne's top dives.

J5 or Intact Submarine - Depth: 36 metres Deep
This unbroken submarine sits on her keel and leans slightly on her starboard side and runs east-west. Her bow faces east while her stern west. Penetration is possible however the stern section and the bow, which contains 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 through the rudder is easy. This is one of the most photographed of the submarines due to the yellow Zoanthids on the conning tower. To dive and or penetrate the J5, the proper certifications are required to be shown, and the use of twin independent or manifold scuba cylinders is highly recommended.
