Here is a complete guide on how to dive the Great Barrier Reef: A Complete Guide
It is no secret that the Great Barrier Reef is one of the best dive sites in the world. On Queensland’s east coast in Australia, there are a lot of fish to see as well as beautiful, vibrant coral that can be seen along the way. As soon as I arrived in Cairns, I was excited to dive the Great Barrier Reef using my newly acquired diving skills while I was there. Everybody tells you how wonderful it is, and I wanted to experience it firsthand to see for myself how great it is.
It is estimated that the reef itself covers over 344,000 square kilometers, which is an enormous area. As a point of comparison, that’s the size of 70 million football fields. It is often considered to be one of the most magnificent natural wonders of the world, and it is so large that it can actually be seen from space, and it attracts over 2 million visitors a year!
As a natural wonder of the world classified by UNESCO, the Great Barrier Reef consists of almost 3,000 individual reefs, making it the largest structure made by living organisms in the world. As a result of climate change and pollution, it has lost nearly 50% of the coral that used to cover this area over the past three decades (the rest is set to disappear within the next century).
In spite of this, there will still be plenty of things to see on your dive! It’s not uncommon for divers to see clownfish (like Nemo! ), groupers, butterflyfish, and possibly even some turtles (there are in fact six species of turtles living around the reef), sharks, and more when they go diving there.

How is the Great Barrier Reef diver’s experience actually like?
There is no denying that diving here is one of the most beautiful experiences of the underwater world, from seeing the vibrant corals to seeing turtles and reef sharks up close. In spite of this, each dive is unique, revealing a different part of this underwater paradise each time.
“From the moment I descended into the blue, I was surrounded by a kaleidoscope of colors and life—giant clams, coral formations, and schools of fish swimming in harmony. The visibility was superb, making every moment feel like I was in an aquarium.”
The Biodiversity of Marine Life and the Marine Environment
It is a well-known fact that the Great Barrier Reef is the habitat of 1,500 species of fish, 400 types of coral, and creatures such as manta rays, reef sharks, and the endangered green sea turtle. In spite of whether you choose to dive shallow coral gardens or deep walls, each reef section showcases a different marine life, which makes multiple dives worthwhile.
The video below is over a decade old, but it still is able to highlight the incredible beauty that exists on the reef. Seeing something like this with our own eyes is something that we have to experience for ourselves. Due to the fact that it is absolutely breathtaking. In addition to that, it is so, so huge!

Here are a few tips on how to dive the Great Barrier Reef.
The following are my thoughts on what I think are the most important considerations to keep in mind when planning a trip to the Great Barrier Reef:
1. Make sure that you plan ahead for the best season possible
-
It is best to visit the Bahamas during the peak season, between June and October, when there is an excellent chance of seeing large marine life as well as optimal water clarity. Nonetheless, if you would prefer to visit when there are fewer crowds, November to May is a good time to visit.
2. Will you be bringing your own gear or will you be renting it?
-
If you are a frequent diver, taking your own gear with you can make diving more comfortable for you.
-
The majority of operators offer a rental service, and the quality of rental gear in Cairns and Port Douglas is outstanding.
3. Being aware of the environment
-
There are a number of environmental pressures that affect the Great Barrier Reef. It is always a good idea to practice reef-safe diving: to avoid touching corals, to use reef-safe sunscreen, and to follow local guidelines.
4. It is important to consider the budget
-
Especially if you’re going on multiple dives or if you’re going on a liveaboard, the costs can add up very quickly. You might be able to find discounted packages or group deals with top-rated operators if you look around.
