The South Australian region near Mt Gambier is known of it’s many sinkholes and caves. One particular cave that stands out amongst the rest is Tank Cave. Tank Cave is probably the most complex and biggest cave system in Australia, with more than eight kilometers of underwater passages. The cave is relatively shallow a max depth around 65ft (20m). This system gets its name from the fact that there used to be a water tank directly over the top of the entrance.

Rumored since the late 1960s as a “cave diving site” of some type, this amazingly extensive feature is today considered by many to be the the best cave diving as far as South Australian cave diving sites

The Tank Cave entrance is on private property and the Cave Divers Association of Australia (CDAA) strictly control access to the dive site. The complicated nature of the cave system, requires a strict familiarization process that allows cave divers to get to know the cave step by step. You must go through this process before you are allowed access to the site, the clear benefit means that every cave diver is very familiar with all the main passages of Tank Cave before they can explore further.

Discover Scuba Diving

If you’re conducting a Discover Scuba Diving program, that’s the more common certification of its kind, they’ll begin with a bit of paperwork, then show you to the instructor. Additional diving certification organizations such as SSI possess similar programs which follow similar, yet differing procedures, all possess the exact same goal; to have a good time and make you be confident and safe within the water.

Plus, you can get credit! If your Discover Scuba Diving program includes an actual scuba dive in open water, your experience may count toward PADI Scuba Diver or Open Water Diver certification, putting you a step ahead of the game when you decide to go for it.

Your instructor will probably have you view a flip chart. The Discover Scuba Diving flip chart will posses vital dive theories and crucial diving rules and ideas which are critical to remember, like the golden rules of diving, 1) Never hold your breath, 2) Equalize your air spaces and ears each couple of meters or as pain is felt.

Next, your instructor will conduct a pre-diving brief explaining the skills, signals and procedures which you’re going to perform within the water, that involve skills for replacing and recovering the regulator, clearing your mask of water, as well as using and finding the different air source. There’re a few additional easy skills which you’ll be expected to perform. Your instructor will assist you with your equipment, then be sure that diving gear will be set up properly.

Then, your instructor will take the group within a pool, or shallow water, that you could stand in. Your instructor should discuss the skill which you’re going to perform, then you’ll go under the water together. Your instructor should first perform the skill, then ask every individual to conduct the skill.

Lastly, your instructor, in most instances, will take your group from the area of teaching, out to the region where they could take you on the underwater tour, showing you an entirely new world. For many, it’ll be a dream come true, and surely one that you’ll recall for a lifetime.
