Stinger Season Is Back. Here's How to Keep Swimming.

Marine stinger season has arrived in North Queensland, typically running from late October through to May. While dangerous jellyfish can be present year-round, the warmer months bring an increased risk.

There’s no need to be alarmed, but there are a few things worth knowing before heading into the water.

What happens at patrolled beaches?

During stinger season, Surf Life Saving Queensland’s lifesavers and lifeguards conduct marine stinger risk assessments, including stinger drags, to monitor for potentially dangerous jellyfish.

They also assess local conditions and communicate risks through beach signage, warning boards and advice to swimmers.

Stinger drags help assess risk but cannot guarantee that jellyfish aren’t present.

Before entering the water, read the beach signage and speak with your local lifesavers or lifeguards. They’ll have the most relevant information for that beach.

The two marine stingers to know

Box jellyfish (Chironex fleckeri)

A large, transparent jellyfish with long, highly venomous tentacles. Found in tropical coastal waters, particularly shallow areas. A significant sting can cause immediate severe pain and can be life-threatening.

Irukandji jellyfish

A group of very small, highly venomous jellyfish that can be difficult to see. A sting may initially feel minor, with serious symptoms developing later, including severe pain, nausea, sweating and cardiovascular complications.

How to reduce your risk

• Swim at patrolled beaches. Follow the advice of lifesavers and lifeguards, including any swimming restrictions.
• Use marine stinger enclosures. Where available, these help reduce the risk from larger jellyfish, but smaller species may still enter.
• Wear a stinger suit. Full-body protective swimwear provides a physical barrier that helps reduce the risk of jellyfish stings. Exposed skin remains vulnerable.
• Read the signs. Conditions and risks vary between beaches and can change daily.
• Never enter the water when authorities advise against swimming.

Not all North Queensland beaches have stinger enclosures. In areas such as Mackay, large tidal movements can make them impractical, making local advice and protective clothing particularly important.

What to do if someone is stung

For a suspected dangerous tropical jellyfish sting:

1. Remove the person from the water if safe.
2. Call Triple Zero (000) and alert a lifesaver or lifeguard.
3. Pour vinegar over the affected area for at least 30 seconds.
4. Do not rub the sting or apply freshwater.
5. Follow emergency first-aid instructions and commence CPR if the person is unresponsive and not breathing normally.

Irukandji symptoms can be delayed, so don’t dismiss a seemingly minor sting.

Enjoy the ocean. Understand the risks.
