J4 Submarine Wreck
The J4 Submarine is a WWI wreck in the Victorian Ships’ Graveyard, lying north–south on a rocky seabed. Divers can enter through several hatches, though the shallow depth makes it prone to strong surge. When conditions are right, the clear, silt-free interior offers one of Melbourne’s best dives.
Inside the J4 Submarine, light streams through cracks, revealing bulkheads, the engine bed, torpedo tubes, and abundant marine life, with fish often around the conning tower.
