Melbourne offers many wreck dives both in the bay and in Bass Strait. These wrecks are very popular with local divers. The J-Class submarines are unique to the area and are dived most weeks. Some wreck are in shallow waters and some can only be investigated with technical training.
The wreck diver course is an introductory course designed for divers to gain skills in diving both externally around wrecks and penetrating the inside when safely possible and there is ambient light within the wreck.
