We are a dive shop operated by divers, for divers. We aim to deliver a variety of quality services that support you in your underwater adventures. We teach. Our team of dive instructors and staff can pretty much teach you whatever you want to learn when it comes to diving. If you’re just starting out, our open water programs are what you want to look at. We offer a wide variety of which are scheduled on a periodic basis. For the more advanced, we offer technical dive training including closed-circuit rebreathers. When you’ve learnt that much you want to teach others, we can teach you that as well with our dive master and instructor programs. We sell. It’s probably no surprise that we sell dive gear, but what we do differently is the variety and quantity that we stock. Our large showroom floor always has the latest models, in a variety of sizes that you can touch, feel and play with before purchasing. The primary brands we stock include Scubapro, Uwatec, Mares, Apollo, and Coltri-sub compressors. We service. Need to rent gear, well we have more of it than we know what to do with including well maintained regs, BCDs, wetsuits of all sizes, and steel and alloy cylinders. If you need gas, we’ve got you covered. We have large storage banks of clean air and pre-mixed Nitrox 32% that you can grab on-the-go whenever our doors are open. We custom blend nitrox up to 100% oxygen without issues, and if you’ve got a rebreather we have trimix, sorb and boosted oxygen to get that machine running. Our qualified service technicians will also diagnose and service all major brands of equipment. We travel. Our trips away are second to none, with a mix of the latest and classic destinations, lots of people to enjoy the trip with, and the best trip leaders to ensure that you don’t end up the creek without a paddle. All of our trips have an upper limit and do fill up, so be sure to get in early or you may miss out. We share. Our dive club is something that we are really proud of. We offer free, dive master led shore dives every weekend to a variety dive sites in and around Sydney. Boat dives and weekend trips are scheduled regularly and include popular locations up and down the coast. Our paid dive club members enjoy free BBQ and light snacks after each dive, as well as getting discounted prices and priority service. We dive. It might come as a surprise, but we dive too. We love it, or we wouldn’t be here.

“What was the first dive you did and how did it influence you to start a career in the diving industry?”

“My first dive was in 1975, in the Persian Gulf around an oil rig, I loved every second of it. I had a break for 10 years and then got into it, became an instructor and the story goes on. Owning a dive shop lets me dive, teach and travel so it is great. I have been teaching for over 25 years and still love it.”

Join our Club! Our dive club hit the waters every weekend (on both Saturday and Sunday) as well as Thursday mornings. It is a great way to meet new people and see some beautiful underwater locations. Check out our Facebook page for more information or give us a call to find out more.

We dive all around Sydney and we decided what site we will be diving at, by picking the site with the best conditions for diving. We also ensure we pick a site which is suited to the level of experience of the divers. Some of the locations which we regularly dive are Bare Island, Kurnell, Gordens Bay, Camp Cove, Voodoo and so many more.

This is a very common question we get to hear at St George Underwater Center, we suggest that once you have completed your open water course take a few dive to get used to using your dive equipment and buoyancy, once you feel confident in the water we suggest taking your diving to the next level. We see lots of people who come and complete their open water course and will only dive once or twice but don’t get in the water again for a few years and sometimes never. By doing this they miss out on the amazing adventure that awaits them underwater. So if you are beginning to ask the question when is it time to complete your advance course, the answer is now.

When a mask is being manufactured an oil residue is sprayed across the glass as the lenses are being cut. This prevents the glass from being scratched during manufacturing. When you take your new mask for a dive or a snorkel the lenses will fog up due to this residue.


Before using your mask for the first time, clean the inside of the mask with your everyday, basic white toothpaste. Place a globe of toothpaste, approximately the size of a 10 cent coin, in to each lens. Using your finger, rub the toothpaste over the entire lens for approximately 3-5mins, then rinse with freshwater. This process helps to remove the fine layer of oil left on the mask.


Another way to help prevent you mask from fogging up during a dive is through the use of an Anti-Fog solution, such as Sea drops or Sea gold, which is used in similar method to toothpaste, but can be applied at the water’s edge.
