The Aqua Sub – a glass underwater viewing area for Great White Sharks!

Want to view Great White Sharks in their natural environment but nervous about entering the cage? Well, we’re here to help with that!

Adventure Bay Charters are proud to introduce the world’s first Shark “Aqua Sub” – a revolutionary new way to naturally view Great White Sharks. This glass viewing area with 360-degree views underwater allows shark observing while staying completely dry!


Aqua Sub

Enjoy lunch or even a glass of wine as you sit back and marvel at the grace and beauty of the Great White Shark.

We still offer Cage Diving as part of our tour, so, if you decide on the day that you want to enter the cage as well, all you need to do is throw on your wetsuit and jump in!

Shark Cage Diving


With the addition of the Aqua Sub to our tour, we can now have 6 people in the Sub and 6 people in the cage at once. With our small group sizes, this means there is no waiting around to see sharks. Half of our boat can be underwater at the one time. No other Shark Cage Dive operator in Australia can provide this. Multiple cage dives and multiple turns in the sub. Book your spot today!

Your day, on board Shark Warrior

Your day begins in our new departure lounge. Check in, enjoy a light breakfast, and browse our selection of merchandise before boarding the Shark Warrior.

Our full day tour takes you from Port Lincoln marina to ‘shark bay’ at Neptune Island, approximately 70 kms south of Port Lincoln, South Australia. On the way, see spectacular scenery as you cruise through the Thorny Passage and expect sightings of inquisitive local dolphins and sea birds.

To ensure we are protecting the natural environment, we use audio sound vibrations to attract the sharks to the boat rather than berley. The benefits of using sound vibration is that it is omnidirectional (that is, it travels in all directions underwater), it’s instantaneous and completely eco friendly – and funnily enough, the great white shark’s favourite choice of music is the rock tunes from AC/DC. Lately they have also taken a liking to The Hilltop Hoods!!

Frequently Asked Questions

Where is Port Lincoln located?

Port Lincoln is located 640km from Adelaide, South Australia. Either a short 45-minute plane flight, or a 7 – 7.5 hour drive.

The shark cage diving is carried out at North Neptune Islands, which is approximately 2 ½ hours boat ride from Port Lincoln.

What is the best time of year to go shark cage diving?

Great White sightings can never be guaranteed as they are wild animals, however most of our tours result in shark sightings. Certainly there are better times than others to have the best chance at a good sighting of Great Whites.

We are always hesitant to say the ‘best’ time of year to swim with the sharks, as they are nomadic and somewhat unpredictable. Historically however, the best time of year for viewing great white sharks is from April through to June. At this time the seal pups that were born in the summer months start leaving the safety of the shore and therefore make an easy food supply for the sharks.

Unfortunately this period is the beginning of our winter months and therefore the chance of bad weather is also increased. Although we will do our best to ensure trips depart, the weather is out of our control and we encourage passengers to contact us 3 days prior to departure for an updated forecast. We also recommend travel insurance in case departures need to be adjusted.

November through to the end of January has always been another great time to dive with the sharks as this is their annual breeding season. The weather is also warmer at this time of year making trips popular in these months.

Although there are strong annual trends in both shark reliability, activity and weather conditions, Great White Sharks can actually be found at the Neptune islands in any given month, and we experience great variations and exceptions to rules every season with both the weather and sharks.

Of course we are always happy to give you up to date information on recent sightings so please contact our friendly team.

What is Adventure Bay Charters commitment toward ecological sustainability?

We aim to undertake continual improvements toward ecological sustainability through the adoption of best practice techniques. We do this by taking feedback from customer’s staff as well as general observations and incorporating these into our policies and procedures. We have a strong relationship with Department of Environment, Water and Natural Resources and ensure that we abide by all current guidelines. We also ensure that at all times we adhere to National Parks and Wildlife Regulations, Marine Parks Regulations and license conditions under the National Parks and Wildlife Act.

Adventure Bay Charters has an environmental management system written specifically for each of its tours. All environmental aspects and impacts are taken into account and this management plan is revised on an annual basis.

Adventure Bay Charters is licensed and operates under the Great White Shark Cage Diving Code of Conduct to promote shark cage diving in South Australia in a professional and responsible manner.

What does it mean to be Advanced Eco-certified?

The ECO Certification logo is a globally recognised brand which assists travellers to choose and experience a genuine and authentic tour or attraction that is environmentally, socially and economically sustainable.

The ECO Certification program assures travellers that certified products are backed by a strong, well managed commitment to sustainable practices and provides high quality nature-based tourism experiences.

Advanced Ecotourism is the highest level of ECO Certification in Australia. It identifies Australia’s leading and most innovative ecotourism products, providing an opportunity to learn about the environment with an operator who is committed to achieving best practice when using resources wisely, contributing to the conservation of the environment and helping local communities.

What are the benefits of acoustic attraction?

Two of the main concerns that scientists have regarding the Great White Shark Cage Diving industry is the use of baits to distract sharks from normal feeding activities and the damage caused to sharks by attacking the shark cage and boat.

We see very different behaviour from sharks attracted by acoustics compared to attraction by berley. By playing music through underwater speakers we encourage curious sharks to venture around the boat to investigate the source of the sound. When sharks are not lured by food they are not as aggressive and do not attack the shark cage or vessel, therefore not causing harm to the very (impressive!) creature that we have come to see!

Adventure Bay Charters’ pioneered the use of acoustic attraction for great white shark cage diving in Australia.

How do I buy a gift voucher?

There are a few ways to buy a gift voucher for someone you love (or hate depending how you look at giving someone a gift to dive with sharks!).

Gift vouchers can be purchased on the website by clicking the book now button on the tour you want, then follow the “Buy a Gift Voucher” button.

If you would like a hard copy gift voucher to be posted out to you just contact us directly on 08 8682 2979 or and we will post or (if your a bit short on time) email a lovely voucher out to you.

Do you have to have diving qualifications to do the tour?

Scuba Diver certification is not required! All dives are surface dives using “hookah” (surface air supply) meaning no cumbersome air tanks! You will only be 2-4 feet below the surface at all times and free to surface at any time. We will provide you with training on the day!

Are there photos from the tour available?

We have a camera on board that the crew use to take photos throughout the day. On the Swim with Sea Lions tour one of the crew will use the underwater camera to take photos of you and our playful, sealy friends. On the Swim with Great Whites tour you get to be the photographer! Just ask the crew for the underwater camera to take in the cage with you and take as many pictures as you like of the sharks, your buddies and of course a selfie of you in the cage!

When we get back from the tour the camera is downloaded at ABC headquarters and you will receive an email 2 days after you tour with a link to download the photos. If you do not have an email please let us know.

You are very welcome to bring your own underwater camera/GoPro if you have one. Remember to upload any cool photos or videos you get onto our Facebook page so the other guests who were on the trip with you can share it!

Let’s stay in touch! #adventurebaycharters
