Why ocean-only

Every minute of your training is on the reef

No pool, no classroom

Your skills sessions happen on the custom training platform in our dive training centre at the Moore Reef pontoon — enclosed, sheltered from wind, 1 to 3 metres deep, shallow enough to stand up in. Open Water students complete 9 training dives across 3 days: 5 here in the sheltered water, then 4 open-water dives on the reef right beside it.

Home every night

No liveaboard, no shared cabin, no nights away. Head out with us in the morning, train on the reef, and you're back in Cairns each evening.

The rest of your day is Moore Reef

Waterslide, underwater observatory, snorkelling, lunch on the pontoon — and whoever you came with gets the full reef day while you're in your course.

A certification the world recognises

SSI certifications are ISO-recognised and accepted at dive centres worldwide. Your digital card lives on your phone, ready whenever you travel.

Your first dives are real dives

Most people's first four dives are in a quarry or a chlorinated pool. Yours are on the Great Barrier Reef.

How it works

Study at home, then dive with us

1

Download the free SSI app

Your theory lives in the app, and so does your certification card once you pass. Create a free account with the email you book with.

2

Do the theory at home

Six sections of digital learning with videos and quizzes — 8 to 12 hours at your own pace, on the couch or on the plane. Finish before you arrive and your days in Cairns are spent in the water.

3

Train at Moore Reef

Skills in the sheltered training centre, then your open water training dives on the reef beside it. Small groups, an SSI instructor with you the whole way.

4

Get certified

Final exam, water fitness evaluation, and your SSI digital card lands on your phone — usually the same day. Recognised worldwide.

Why SSI

Why we teach SSI

SSI and PADI are both recognised worldwide, and the card you walk away with is the same either way: certified to 18 metres. What differs is how the course is taught.

Skip it, come back to it

SSI lets you leave a skill and return to it when you feel ready. If mask clearing takes you three goes, you move on and come back, rather than being stuck on it while the group waits. When you are new and a bit nervous, that matters more than it sounds.

4 students to 1 instructor

Small groups are the SSI standard and they are why there is time to do that. You are not one of twelve people waiting for a turn.

The agencies work together

Anything below Master level is interchangeable. Do your Open Water with us and your Advanced somewhere else, or arrive with a PADI card and keep going with SSI. Nothing you have already earned is wasted.

Good to know

Questions everyone asks

What's the minimum age?

It depends on the programme. Introductory (non-certified) dives are 12 and up, which is the minimum Queensland's code of practice sets for non-certified diving. The SSI Open Water Diver course starts at 10: divers aged 10 and 11 are limited to 12 m and train in a smaller group: no more than 2 children aged 10 or 11 with one instructor, and no more than 4 people in the group. The Advanced Open Water and Diver Stress and Rescue courses are 12 and up. Anyone certified under 15 receives a Junior Diver certification and dives with a dive professional or a certified adult until they turn 15, when it upgrades automatically. Divers under 18 need a parent or guardian to sign a consent form and to be present.

Do I need a medical?

Every diver completes the RSTC Diver Medical questionnaire before getting in the water. All “no” answers and you're cleared to dive. Any “yes” needs a doctor's signature first — we send the form at booking so you can sort it at home.

Do I need to be able to swim?

For the Intro Reef Dive you need to be reasonably comfortable in the water — your instructor stays with you the whole dive. Certification courses include a swim evaluation.

How long before my flight home?

Allow at least 18 hours between your last dive and any flight. Don't book a course right up against your departure.

I certified with PADI years ago — can I do your courses?

Yes. PADI, SDI and NAUI certifications are recognised for our continuing education courses and refreshers.

Can I cancel or reschedule my course?

Yes. Free cancellation or rescheduling up to 5 days before your course commences.

When do courses start?

Open Water and Advanced Open Water are bookable now. Pick your dates on the course pages and you will see live availability for every departure. Diver Stress & Rescue runs on request — use the form on that page and our reservations team will come back to you with dates. Intro Reef Dive and Return to Diving can be booked now too.
