Today – November 2023 the stinger nets are in use on Four Mile Beach, it is stinger season 2023. Stinger season will continue into 2024. Most reef boats have started handing out stinger suits and you should only swim in the stinger net at Four Mile Beach and the Cairns beaches. We are in Port Douglas and Cairns now, one of our team works on the reef, our site is updated with current, first-hand information as often as possible. Reef cruises, snorkelling and scuba trips operate throughout stinger season and are only cancelled in the event of extreme weather.

We can also give you ideas on local, safe, stunning freshwater swimming spots. No trip to the region is complete without visiting one of our jungle swimming holes

There are more creatures to consider in this part of the world, starting with saltwater crocodiles, you can read what life is like for us living with these prehistoric monsters or discover where to spot our crocs in the wild, I kinda love them.

It’s not just the stingers, crocs, snakes and spiders that are out to get you, we also have a stinging tree, but seriously, don’t worry! She’ll be ‘right, as they say in Australia.

We hope you enjoy your visit to our old home (we left to travel the world, long story, it wasn’t because of the wildlife) and that you get the most out of Far North Queensland.

Marine Stingers and Dangerous Jellyfish in Queensland, What are They?

The two most dangerous jellyfish, the ones we worry about in stinger season, are the box jellyfish and Irukandji.

Stinger 1. Box Jellyfish

The most poisonous and deadly jellyfish in the world likes to hang out around Australia. The venom can kill in minutes and is the cause of an average 1 death per year in Australian waters.

There are more deaths in South East Asia, where stinger nets are rare. This jellyfish can get large, with tentacles stretching up to 3m behind it.

Stinger 2. Irukandji

The tiny Irukandji is the smallest member of the box jellyfish family, it takes its name from the Irukandje people of Northern Australia and measures around 5mm in diameter. Its tentacles can be up to 1m long.

Its tiny size is deceiving as its venom is incredibly strong. Death isn’t inevitable, but Irukandji syndrome isn’t a nice thing to have, symptoms include severe muscle cramps, intense back pain, vomiting, racing heart and a feeling of intense doom.

The Irukandji is the reason many of us wear stinger suits inside the nets, they can be tiny enough to pass through the mesh of the net.

Stinger Season Cairns and Port Douglas Dates

If you’re here just for the hard facts, Stinger season is roughly November to May, but there is more to the story than that.

In Port Douglas, down the road in Cairns and throughout Far North Queensland including the Whitsundays, Townsville and Hamilton Island, stinger season comes with summer.

Things get sticky and with the heat and humidity come the most dangerous jellyfish. We call them marine stingers. However, some jellyfish can be here all the time, we don’t worry about them too much.

The occasional blue bottle, lonely jelly blubbers, and swarms of annoying sea lice visit from time to time, but they aren’t a big problem. Summer is the real danger time, we call it stinger season or jellyfish season.

From around November, it isn’t sensible to swim unprotected from Four Mile Beach or any of the Northern Beaches. Deadly box jellyfish and Irukandji can visit our waters and we should all use the stinger nets when swimming from the shore and a one-piece stinger or sunsuit becomes a very good idea. (See where to buy one below)

Beautiful Port Douglas. But is it safe to swim?

Is it Still Stinger Season Today in Port Douglas?

Today, – November 2023 – the stinger nets are on the beach in Port Douglas. It is stinger season.

There were beach closures due to rough weather in the last few weeks but there were people swimming on Four Mile Beach this week.

I keep this post as updated as possible and I’ll post here when the stinger nets are on the beach, year-round.

Beach Closures During Stinger Season

Beach Closed sign Australia Stinger Net Beach Closed Port Douglas Dangerous to Swim

Sometimes during summer the stinger net on Four Mile Beach will be closed intermittently due to the presence of dangerous Irukandje small enough to pass through the net.

At other times during stinger season swimming and conditions are beautiful.

Beach closures during stinger season are fairly unusual. During the wet season, conditions can be very still, but stormy weather can also bring beach and stinger net closures.

The stinger nets are not fool proof, tiny jellyfish can easily get in if they are in the area and the lifeguards check the net often.

When is Stinger Season Around Tropical North Queensland Region?

The further north you go, the longer stinger season lasts.

The marine stingers enjoy warm water and hanging out in mangroves.

Exact dates vary, there is no fixed point but generally expect the season to run from November or December to March between Gladstone and Townsville, October to June in the far north.

While we’ve been living in FNQ the stinger season Port Douglas has generally lasted from November to May, Cairns will be the same.

The Stinger Nets Will be Out

Stinger season Port Douglas and Cairns stretches from around the first of November to May, the stinger nets will be in the water as soon as there is any possible danger.

The best times for swimming here, we think, are on the shoulders of stinger season, just before and just after the stinger nets go out.

The water is warm and can be crystal clear, you’ll find us hitting the beach with the kids most days then.

Beaches With Stinger Nets Around Cairns and Port Douglas

There is a stinger net at the lifeguard station at the top end of Four Mile Beach, Port Douglas.

Tourists use it right through stinger season.

The net is occasionally closed in stormy weather.

You’ll also find stinger nets at Palm Cove, Clifton Beach, Yorkey’s Knob, Holloways Beach, Trinity Beach, Kewarra Beach and Ellis Beach, most beaches in the area.

How Will Stinger Season Affect Your Great Barrier Reef Trip?

Things are safer on the Great Barrier Reef, your chances of encountering stingers are very small, even in Stinger Season so don’t worry too much about stinger danger on your day trip from Port Douglas

All reef charter boats have head to toe Stinger Suits on board for snorkellers to hire or use. They’re not elegant, but  you need to wear one in stinger season.

It’s a great idea to buy a suit for your kids to keep our fierce sun off their skin at the beach, along with the marine stingers.

This is perfectly normal in Australia, many kids wear them at any time of year.

stinger season port douglas and cairns
Stinger warning signs like these are on the Cairns and Port Douglas region beaches year-round, the bottle beneath contains vinegar, a good treatment or some stinger stings.

You’ll sometimes see local children in full-body stinger suits, exposing only fingers and faces, inside the net.

Stinger nets are potentially not 100% effective, tiny jellyfish can still, possibly, pass through.

Don’t be put off, you’ll also see plenty of people in bikinis. The stinger suits serve a dual purpose, we also use them to protect our kids from the sun.

The lifeguards drag the net, usually every day, to check for any unwanted visitors. Look out for them, it’s interesting to see all the small fish and invertebrates they catch. They’re usually a friendly bunch.

Out on the reef the risk of marine stingers is even lower but most reef boats carry stinger suits to loan or hire to all passengers.

If you are snorkelling on The Great Barrier Reef you will be required to wear one in Stinger Season. Likewise, if you are learning to scuba dive, enjoying a trial dive, taking a liveaboard dive trip, or anything else that puts you in the water, you’ll need a stinger suit.

Stinger suits are also a very good idea to protect your children from the harsh Queensland sun.

High UV levels in Cairns and Port Douglas make stinger suits or sun protective suits a very good idea, even outside stinger season.

Buy a Stinger Suit Here

If you’d like to buy your own stinger suits to use on the beaches as well as on the reef, have a look here for kids’ and adults’ stinger suits and rash vests. (works for USA, UK and more).

If you’re wanting to buy stinger suits in Australia try here.

Is it Safe to Swim in Stinger Season in Queensland Australia?

Stinger suits on the Great Barrier Reef in wet season or stinger season
My family visiting the Great Barrier Reef in stinger season. The black stinger suits were provided by the charter boat. My younger son wore his over his rashie and shorts. The suits have hoods and mittens leaving only tiny areas of skin exposed.

Thousands of visitors swim from Four Mile Beach all year round and problems are very rare. To be safe, take precautions:

  • Check the lifeguards’ instructions on the boards, you’ll find them on the beaches.
  • If the lifeguards say it’s safe, only swim in the stinger nets.
  • Wear a stinger suit or as much body protection as you can, rashies and board shorts help.
  • Do not touch the nets themselves, stingers could be caught in the net.

For my family, we reduced our sea swimming in season, after all, we lived here all year round and could swim any time.  

We continued to visit the reef or Low Isles and felt very safe. Stingers prefer to hang out near the coastal estuaries.

It’s great to visit hotel pools, the Cairns Lagoon, or some of our natural, fresh-water swimming spots at this time of year, after all, there are plenty of other things to do in Cairns or Port Douglas.

Other Places to Swim Around Port Douglas and Cairns, Swimming Holes, Pools, and The Lagoon.

Safe Swimming Port Douglas

Sea Temple Port Douglas Swimming Pool Best

If you are staying at any of the Port Douglas hotels, chances are you will have a pool. But there are also nearby freshwater swimming spots to try.

Most places in Port, from campsites to hostels, have their own pools. Top-end Sea Temple (pictured above)  has an outstandingly huge and luxurious pool with lagoons, rivers, a hot tub and bridges to swim under.

It’s one of the biggest and best in the world and we would spend every Christmas there along with many locals. The pool at The Sheraton Grand Mirage is even bigger.

Hotels in Port Douglas With Stunning Pools

Hotels in Cairns With Good Pools

  • Novotel Cairns Oasis Resort Novotel are a great up-market chain of hotels and they do family and kids really well. We always expect high standards with Novotel.

Safe Swimming at Port Douglas in Stinger Season

There are some really lovely places to swim around Port Douglas, some of the hotels allow visitors to use their pools if they are buying food or drinks and Mossman Gorge (click here for rainforest swimming information) is just up the road, perfect for a cooling dip in an icy cold rainforest stream.

Swimming is now discouraged at Mossman Gorge and you may see “no swimming” signs depending on time of year. There have been deaths here, unfortunately.

Safe Swimming Cairns in Stinger Season

Cairns has one of the most amazing Lagoon pools in the world, and it’s free.

There is also a small waterpark in Cairns, see this post on places to get wet in the area. There are a few natural rainforest swimming spots nearby, we particularly enjoy Crystal Cascades. 

Fresh-water swimming in this part of the world is an experience you shouldn’t miss.

Maybe stinger season isn’t the best time to visit Port Douglas, but you’ll find plenty of things to do in Port Douglas, safely and enjoyably at most times of the year.

Fabulous Four Mile Beach, Port Douglas.

Stinger season is just one of the costs of living in the tropics, sharing our lives with deadly but fascinating creatures, crocodiles, snakes, and spiders.

It’s always beautiful here in Port Douglas and the wildlife and scenery are stunning, all year round.

Four Mile Beach, our home, is beautiful, but once the dangerous jellyfish arrive and stinger season starts, just use a bit of common sense.

You have to make your own call, you should be fine inside the stinger net and you’ll be safer still on the reef.

Just keep it in your mind and listen to the lifeguards, they drag the net every day to check for stingers.

They know the beach and know when the risk is high, they will tell you.

Thanks...Very informative article. Kind of a downer for me as I'm flying into Australia in middle of May for vacation from the states. I have always wanted to experience the GBR but seems my schedule lands me there right in the stinger season. I never even realized this was such a serious dangerous issue. I've travelled many tropical locations to snorkel and dive but this is first I've heard of the real and possible deadly dangers of the area regarding these jellyfish.

Part of my worry is also about the Irukanji and from what I read is particularly dangerous for people on anti-coagulants and high blood pressure (which unfortunately I have both)

I had planned to do a live aboard snorkel cruise in middle of May but now wondering if I should cancel and just stick to the cities and stay south. I feel it's in my head now and when I enter the water it'll be all I think about. :)

Would you suggest me changing the date of trip to come later in June or July if I can?

@Alyson Long, Great. Thanks for quick response. Look forward to trip!

No, May is the end of the seasonn, very low chance. If you cover your body with suits, that should be OK. I wouldn't go in wearing Speedos but I doubt you'd find any skipper who would let you do that. There are much bigger dangers than jellies. Everyone snorkels and scuba dives year round. Australia is rare in that it announces stinger season. Other countries have it, just don't mention it. I live here, my husband works on the reef , I take my kids out's not a massive big deal with sensible precautions, like just wearing a stinger suit. But obviously this is not medical advice.


Tuesday 26th of July 2022

Hi Alyson, Loved your very informative article. My husband and I are travelling from Canada to Australia next February. Fingers crossed it doesn't get cancelled again. We've only got 2 days in Port Douglas and are planning one day for the Daintree Rainforest, and our second day for a Great Barrier Reef tour. I'm prone to seasickness. Should we just do a half day tour? Do you have any recommendations for companies with faster boats to help prevent that?

Alyson for World Travel Family

Wednesday 27th of July 2022

Hi Kim, There are half day tours to Low Isles, some on little red jet boats, Reef Sprinter, and they also go out to Tongue Reef which isn't as "outer reef" as the reefs most of the boats go to. February isn't the worst time for seasickness, that's now because of the trade winds but, if there are tropical storms around there is a chance there will be no boats running at all for a few days. If you get lucky you could also see incredible conditions in February. A lot of people do get sea sick. My husband works on one of the boats and deals with sick passengers daily. He says the hydrobromide seasickness tablets work, the antihistamines aren't as good because they knock you out. Most people do recover once they jump in the water though. If you choose a half day trip to Low Isles, the snorkelling is still great, but you won't see the hard corals so much, there's a lot of soft coral, turtles, juvenile fish. It's great snorkelling and it's actually a good idea to visit both if you can. Also, if there is a cyclone or tropical storm about, you won't be able to get to the Daintree as there's usually flooding. But cyclones are rare. Best of luck.

Looove this page and all the effort you have put into this!! Currently looking to go up there for a 5 day trip in june. Just our 4year old, hubby and me. Any great ideas especially for 4 year olds? (We live in Melbourne and i personally can not waaait to experience tropical landscapes)

Tuesday 27th of April 2021

Thank you, Charlotte. Glad to be helpful. In June just remember it could be kinda chilly-ish in the water. Some swimming pools will be cold too. Currently, we still have issues thanks to lockdown with restaurants not being able to open at all or only being open on weekends, no staff etc. Boats aren't necessarily running every day, so book. I can't see much changing by June unfortunately. Prices for car hire have been crazy too. It's usually best not to pick up a car from the airport, but right now, it's the only place you can get one. It's a terrible rip-off. A lot of our decent shops closed too and won't be back until the international tourists are back. Hopefully by the end of this year we can all start living our lives again.

I am planning on travelling in May or June 2021 and was very much wanting to swim in the ocean with my children. Would it be safer to swim with the nets in place in May or after the stinger season is over in June? I would make sure everyone was wearing stinger suits

Alyson for World Travel Family

Tuesday 27th of October 2020

Kate, plenty of people swim in the nets without incident. If the sea is rough the nets may be closed, but that's not common. Last year the nets were also closed for a while because people were stung in the nets, but mostly, they're open and people use them. It did seem to be a very bad year for stingers last year, fingers crossed this year won't be. Stinger season now officially starts in November, from next week the stinger nets will be in place.


Monday 11th of November 2019


Thanks for the great read. We are right now in australia and noticed that most of the beaches we go to are completely empty ever since we left Hervey Bay to go north. We are so many beaches, today at Mackay, but we are very hesitant to go and take a swim. Your post mostly answered our feared question; can we still swing at this point in the season at unguarded beaches? We are going more and more north towards Cairns the coming two weeks.

Love to hear your thoughts on it:)

Kind regards,


PS we love it here so far, able to swim or not, everything is just so beautiful. We envy you get to live here every day ;)

The beaches are empty because so few people live here Yvan. Quite a few locals don't even worry about stinger season and just carry on as normal if they're fishermen or whatever. I don't know if it's started up here or not yet, but you're a lot further south. It starts first in the north and moves south. Also it's low season now, kids are in school, not many tourists. As locals, we don't go to the beach, ever. We run on it at dawn. Otherwise we never, ever go there. Which is why I don't know if it's started yet or not, I haven't been to the beach to see if the nets are out. No nets, not started yet. Once the sun is fully up we don't even go outside. So if you see a beach with a lifeguard station and ropes for nets and nets not out, you should be good still.
