Green Island has been a famous Cairns destination for decades. Here’s why
- Written by: The Times

For generations of visitors to Cairns, a trip to Green Island has been almost a rite of passage.
It appears almost impossibly tropical: a small coral cay covered in rainforest, surrounded by blue-green water and the Great Barrier Reef.
Yet one of Green Island's greatest attractions is not simply what is there.
It is how accessible it is.
You can wake up in a Cairns hotel, walk down to the marina, board a boat and, before too long, find yourself standing on a sandy island on the Great Barrier Reef.
That combination of accessibility, reef, rainforest, beaches and history helps explain why Green Island has remained one of Cairns' best-known attractions for decades.
Where is Green Island?
Green Island lies approximately 27 kilometres offshore from Cairns.
It is part of the Great Barrier Reef Marine Park and is unusual because it is both a coral cay and home to rainforest vegetation.
The island itself is small enough to explore on foot.
That makes the experience quite different from visiting a large tropical island where transport becomes part of the holiday.
At Green Island, you get off the boat and you are essentially there.
Beach, rainforest and reef are all within walking distance.
How long does it take to get there?
This is one reason Green Island became such an enduring Cairns attraction.
Fast catamaran services can make the journey from Cairns in around 45 minutes.
There is no lengthy road trip before boarding a vessel and no need to change accommodation.
For visitors staying in Cairns, Green Island can easily be a day trip.
That convenience matters.
A family visiting Cairns for four or five days can include a genuine Great Barrier Reef island experience without reorganising the entire holiday around it.
Why is Green Island famous?
Green Island tourism has a remarkably long history.
Visitors have been travelling to the island commercially for almost a century.
Over the decades it became one of the places through which generations of Australians and international tourists first encountered the Great Barrier Reef.
Long before today's enormous tourism industry developed around Cairns, Green Island was already drawing visitors offshore.
That history gives it a special place in the development of Cairns as an international tourism destination.
But history alone would not have kept people coming.
Green Island has survived as an attraction because the basic proposition remains compelling.
You can leave Cairns in the morning and spend the day on a tropical island surrounded by the Great Barrier Reef.
Is Green Island actually part of the Great Barrier Reef?
Yes.
This isn't merely an island close to the reef.
Green Island is a coral cay within the Great Barrier Reef World Heritage Area.
A coral cay forms through the accumulation of sand, coral fragments and other reef material.
Over a very long period, vegetation becomes established.
Green Island is particularly interesting because mature rainforest now grows on the cay.
That gives visitors two major natural environments in one place.
Walk through tropical vegetation on land and then enter the marine environment surrounding it.
Can you snorkel at Green Island?
Yes.
Snorkelling is one of the principal reasons people visit.
Equipment can be hired and tour packages may include snorkelling equipment.
The advantage for inexperienced snorkellers is accessibility.
Rather than experiencing the Great Barrier Reef exclusively by jumping from a boat into deeper water, Green Island provides the psychological comfort of having land nearby.
Conditions vary, however.
Visibility, tides, weather and currents can affect the experience, and visitors should follow local instructions about where and when to enter the water.
Being a confident swimmer in a suburban swimming pool does not automatically make somebody experienced in tropical ocean conditions.
Use the designated swimming areas and follow the advice provided on the island.
What if I don't want to snorkel?
You can still go.
This is another reason Green Island appeals to such a broad range of visitors.
Glass-bottom boat tours provide a way to see coral and marine life without entering the water.
You can also simply walk the island, explore the rainforest, sit on the beach, swim where conditions permit or enjoy being somewhere that feels much farther from Cairns than the relatively short boat journey suggests.
For families or groups containing swimmers and non-swimmers, this flexibility is valuable.
Everyone does not have to participate in exactly the same activity.
Is there a sandy beach?
Very much so.
Green Island provides the sandy tropical beach experience that central Cairns itself does not.
This distinction can surprise first-time visitors.
Cairns is a waterfront city, but its Esplanade looks across tidal flats rather than a conventional swimming beach.
Green Island provides almost the opposite experience.
Sand, tropical vegetation and reef water are immediately in front of you.
It is one of the easiest ways for a visitor staying in central Cairns to transform a city holiday into a tropical island holiday for a day.
Can I see turtles?
Green turtles and other marine life occur in the waters around Green Island.
There is never a guarantee that wildlife will appear on command, of course.
That uncertainty is part of visiting a natural environment.
Depending upon conditions and luck, visitors may encounter fish, turtles, rays and numerous other reef species.
The important thing is to observe wildlife without interfering with it.
The Great Barrier Reef is not an aquarium.
It is a living ecosystem.
What about crocodiles and marine stingers?
Green Island is in tropical North Queensland, so the normal rules about tropical marine environments apply.
Marine stingers are a greater concern during the warmer months, generally around November to May, although visitors should follow current local advice at any time of year.
Protective stinger suits may be recommended or supplied depending on conditions and tour arrangements.
Crocodiles inhabit tropical northern Queensland and can occur in coastal waters.
Visitors should therefore swim only where advised and obey any warnings or closures.
The rule throughout the Cairns region is straightforward:
Local safety advice beats assumptions.
If an area is closed, don't swim there.
If staff recommend protective clothing, wear it.
Is Green Island good for children?
It can be an excellent family excursion.
The relatively short journey from Cairns is an advantage compared with longer offshore expeditions, particularly with younger children.
There is also more to do than snorkelling.
Families can combine beach time, walking, swimming and glass-bottom boat experiences.
Parents should remember, however, that this remains an island surrounded by ocean.
Children require appropriate supervision around water regardless of how calm or inviting conditions appear.
Green Island or an outer reef trip?
This is probably the most important question for visitors with limited time.
They are different experiences.
An outer reef trip is primarily about getting farther offshore and experiencing reef locations selected specifically for coral and marine activities.
Green Island is more of a combined island and reef experience.
You get the sandy beach.
You get rainforest.
You can walk around.
You can snorkel.
You can look at the reef without entering the water.
And you have somewhere solid to spend the day rather than remaining on a vessel or pontoon.
If your absolute priority is seeing the most spectacular coral possible, investigate the various outer-reef tours and compare their destinations.
If you want the broader experience of going to a tropical island on the Great Barrier Reef, Green Island has an obvious appeal.
And if you have enough time in Cairns, there is a strong case for doing both.
Can you stay overnight?
Yes.
Green Island is not exclusively a day-trip destination.
Accommodation is available on the island, giving overnight guests a very different experience after many day visitors have returned to Cairns.
There is something particularly appealing about being on a Great Barrier Reef island after the day's tourism traffic subsides.
It also transforms Green Island from an excursion into a genuine tropical island stay.
For most Cairns visitors, however, a day trip will be enough to understand why the island became famous.
How much time should I allow?
A full-day visit is the best option if your itinerary allows it.
Half-day options can suit travellers with limited time, but rushing an island seems slightly contrary to the point of going there.
A full day gives you time to snorkel, explore, eat, sit on the beach and simply enjoy the location.
Not every holiday attraction needs to be consumed as quickly as possible.
Green Island rewards slowing down.
Is Green Island worth visiting?
For a first-time Cairns visitor, we think it deserves serious consideration.
There are more remote reef locations.
There are larger islands.
There are reef tours designed specifically for experienced divers and snorkellers.
Green Island's strength is that it combines several experiences remarkably efficiently.
Cairns city → boat → tropical island → rainforest → sandy beach → Great Barrier Reef.
And all of that can happen in a single day.
Cairns Times View
Green Island has been part of the Cairns tourism story for generations because it solves one of the great challenges of visiting the Great Barrier Reef: making an extraordinary natural environment relatively easy to experience.
You don't need to be a diver.
You don't need to stay on an island.
You don't need a car.
You don't need an expedition.
You can walk from your Cairns accommodation to the waterfront, board a boat and soon find yourself standing on a tiny rainforest-covered coral cay surrounded by the Great Barrier Reef.
There may be newer attractions and more adventurous ways to explore Tropical North Queensland.
But sometimes longevity tells you something.
Green Island became one of Cairns' famous destinations decades ago.
There are still very good reasons why.
