The Tasmanian Scuba Diving Club (TSDC) is one of the oldest scuba diving clubs in Australia. It was formed in Hobart in 1967 when the Army Scuba Diving Club decided to establish a civilian arm, with the aim of "fostering the sport of scuba diving". The TSDC quickly established itself in the local diving community.

At that time little dive gear was available for purchase and a lot of war surplus diving equipment could be found in various states of disrepair. Diving at that time mostly attracted fit young males who had started spearfishing as boys. The rest of Hobart thought they were all foolhardy for taking on such a dangerous sport. Crayfishing was the main activity and in those days one diver could get a bagful of huge crayfish after just one dive at the Iron Pot.

The opening of stores like Aqua Scuba in the late 1960s allowed diving to take off locally by offering both training, and affordable, reliable equipment. Increasing interest in diving was also spurred on by popular films such as Beau Bridge's "Sea Quest", the drama "The Barrier Reef' and Jacques Yves Cousteau's many documentaries.

In its early years, the TSDC also ran its own training courses, heavily influenced by the BSAC training system from Britain. When professional training organizations arrived in Australia (year? Decade?) the Club instructors formed the core of a new breed of professional instructors that expanded the local diving market in Hobart and around Tasmania.

The 1980s saw the increased involvement of a wider section of the community in recreational diving, especially women. Gone were the days of the macho male ex-spearfisherman who had made up the core of the Club’s members previously. By now, the Club’s members were a more diverse group of people, just as likely to be interested in photography as catching crayfish. By the mid- 1980s the Club had accumulated the funds for its own boat, allowing it to travel further to explore new dive sites in greater safety and comfort.

Forty years later, the Club is onto its fourth boat, and is still very much an active and innovative community-based organization with members from every walk of life. We do every sort of diving and are out almost every weekend. The focus has changed from an emphasis on crayfishing 40 years ago to a wider appreciation of the spectacular underwater scenery, unique marine life, sponge gardens, caverns, wrecks, marine conservation and photographic opportunities offered in Tasmania’s waters.
