Book Your Great Barrier Reef Scuba Diving Adventure

Why book a Great Barrier Reef Scuba Diving Tour?

Home to vibrant coral gardens, sea turtles, reef sharks, and thousands of species you won’t find anywhere else and spanning over 2,300+km, the best way to truly experience the Great Barrier Reef is to go**** beneath the surface.

Scuba diving tours let you float beside clownfish, explore coral canyons, and experience one of the planet’s most biodiverse marine ecosystems from eye level. Whether you're a seasoned diver or it's your first time breathing underwater, there’s a tour made just for you.

Here’s why a diving tour is worth it:

It’s beginner-friendly
Never dived before? Many tours offer supervised intro dives—no certification required.
See rare marine life up close
From turtles to reef sharks, the underwater world is full of surprises.
Best visibility on the reef
You’ll dive in hand-picked locations with clear water and vibrant coral.
Everything’s included
Gear, guides, safety briefings, and lunch are included. Just bring a towel and a change of clothes if you wish.

What’s included in Scuba Diving Tours

Every tour varies slightly, but here’s what most Great Barrier Reef diving experiences include:

Round-trip transfers from Cairns
All scuba diving equipment (mask, fins, Lycra wetsuit, tank, etc.)

Tips for your first Great Barrier Reef dive

Don’t worry if you’re a beginner:
Introductory dives are safe, shallow, and supervised—just follow instructions and enjoy.
Bring motion sickness tablets:
Reef waters can be choppy. Take a tablet 30 minutes before boarding if you’re prone to seasickness.
Wear reef-safe sunscreen:
Protect marine life by using biodegradable, non-toxic SPF.
Book early in peak months:
July to October sees high demand and excellent visibility.
Listen to your dive master:
Safety is everything. Plus, they’ll help you spot sea turtles and hidden gems.
