Scuba Diving the Great Barrier Reef in Cairns – Is it worth it?

The Great Barrier Reef is the world’s most extensive grouping of coral reefs, consisting of nearly 3000 reefs and acting as the home for thousands more marine species.

This diverse array of coral and marine life means that scuba diving the Great Barrier Reefs is one of Australia’s most popular tourist activities, especially from the city of Cairns. 

The reef is so famous that around three million people visit the site every year and is a significant contributor to the economy of the Queensland coast.

But the question remains: Is scuba diving in the Great Barrier Reef actually worth the money?

Although thousands of scuba diving tours operate out of Cairns every day to support tourist demand, they usually have a hefty price tag to match.

Truth be told, scuba diving in itself is an expensive adventure sport. 

Over the years, I have heard many mixed opinions about the Great Barrier Reef.

Especially when it comes to the bleaching of the coral and whether it has made this once-upon-a-time a “bucket list item”, no longer worth the money to see.

I have also scuba dived in the Great Barrier Reef from Cairns multiple times, so will share some of my own personal experiences as well.

But first, let’s cover off some of the basic facts you should know about the Great Barrier Reef.

All You Need to Know About the Great Barrier Reef in Cairns

The Great Barrier Reef is located in the aptly named Coral Sea found off the east coast of Australia. It was the first coral reef recognised as a UNESCO world heritage site in 1981 and is one of the world’s most extensive ecosystems.

The reef stretches over 2,300 kilometres of coastline and can even be seen from space! However, the best way to view this natural marvel is strap on your scuba gear and descend under the waves.

The Great Barrier Reef is a vast composite reef that is made up of approximately 2,900 unique reef formations that can range in size from anywhere between 1 hectare to a staggering 100,000 hectares.

This is why I don’t believe anyone can truly say that as a whole, the Great Barrier Reef is not worth visiting. T

here are just so many different pockets and reefs to explore. 

It is currently estimated that over 1,500 different species of fish have made their home in the Great Barrier Reef, representing at least 10% of the known species of fish in the world.

Other common marine animals found in the Great Barrier Reef include dolphins, whales, dugongs, manta rays, marine turtles and many more.

Thanks to its proximity to the Great Barrier Reef, the city of Cairns is one of the best cities in Australia to explore this fantastic underwater paradise.

Its location off the coast of Queensland, its fantastic marine tourism industry and its sheer size make it the perfect destination for adventurous scuba divers.

It is even a great place for beginner divers wanting to tick one of the world’s greatest dive sites off their bucket list.

So in summary, the “awesomeness” of your scuba diving adventure could come down to good luck.

To help you improve your likelihood of having an amazing experience scuba diving, we have listed the top five dive spots in the Great Barrier Reef near Cairns.

5) Hasting Reefs 

Located about 50 kilometres from Cairns, Hasting Reefs is set on the Outer Edge Reef, where the Great Barrier Reef began nearly 15,000 years ago.

Spanning a ten square kilometre patch of ocean, Hasting Reefs encompasses a breath-taking collection of corals and wildly exotic fish.

The average depth is around 13 meters deep and so it is the perfect location for both beginners and experts, with plenty of beautiful coral gardens as well as a network of cave systems that make the region feel diverse.


4) Flynn Reef

Flynn Reef is one of Australia’s most diverse dive locations and is home to many well-known dive sites, including Tracy’s Boomie, Tennis Court, Coral Gardens and Gordon’s Mooring.

It is located around 60km from Cairns and divers who visit this fantastic reef will discover an abundance of marine life including:

  • Nemo-like clownfish
  • Dolphins
  • Turtles and
  • White-tip reef sharks

With an average dive depth of 13 meters, the site is also excellent for beginners, while the unique range of wall dives on the edge of the reef allows for some more advanced dive types.

However, when visiting the reef from November to December, you will see the corals during their annual spawning, a spectacular sight.

If you are a more experienced diver, you can visit Flynn Reef on a night dive when marine life is more active and you can see barracudas and sharks feeding.

2) Cod Hole 

Located roughly 96 kilometres north of Cairns, the Cod Hole is part of the string of narrow reefs known as the Ribbon Reefs.

The Cod Hole is perfect for all levels of scuba divers and its depth varies from 10 to 30m with gentle currents, making it one of the Great Barrier Reefs best dive locations.

The variation in depths and unique current patterns means that visitors to Cod Hole can discover:

  • Giant clams

Heading to the edge of this reef will bring a diver to the start of the open ocean and is a great location to spot dolphins and even sharks.


1) Eddy Reef

One of the Great Barrier Reefs more challenging locations, Eddy Reef is found 118 kilometres from Cairns.

All dives to this site begin by dropping you off at the edge of the reef from where you will catch the powerful current that takes you on a whistle-stop tour of this fantastic site.

So, is it Worth Scuba Diving in the Great Barrier Reef?

In my opinion, the Great Barrier Reef is still 100% worth a visit, even if to just tick it off your bucket list.

Although it has received a bad rep globally for being impacted by coral bleaching and the crown-of-thorns starfish, your experience will really depend on when and where you go. After all, there are so many different reefs to explore!

Personally, I’ve had mixed experiences scuba diving in the Great Barrier Reef from Cairns.

I have had moments where I’ve been in complete “awe” swimming alongside graceful sea turtles, and others where I’ve felt extremely disappointed because the visibility was sh**.

Personally, I feel that you just have to go there to experience it yourself and with the intention of making the most of it – even if one or two dives don’t quite reach your expectations.

If you visit a dive site at the right time of the year, you could have the chance to see playful fish or even roaming pods of whales!!

In Summary:

Scuba Diving the Great Barrier Reef in Cairns – Is it worth it?

In my opinion, yes. Although there are some parts of the reef which are said to be disappointing (due to coral bleaching etc), the Great Barrier Reef is HUGE!

There are still many great dive sites to enjoy along the Great Barrier Reef, especially off the coast of Cairns.  

Each person’s experience will be unique and depends on seasonality, water currents, level of diving experience and the dive site visited.

If you do find yourself disappointed with your first dive (eg. coral not as colourful as you expected), I highly recommend doing a second and even third drive at a different location.

Happy diving!
