🐙 Box Jellyfish and Irukandji – What You Need to Know Before Your Reef Tour

If you’re planning a Great Barrier Reef adventure, it’s natural to have questions about marine stingers like Box Jellyfish and Irukandji. These creatures are part of life in the tropics — but with the right precautions, exploring the reef is safe, exciting, and absolutely unforgettable.

This page will help you understand the facts and feel confident about enjoying your day on the reef.

🧭 Are Box Jellyfish Found on the Great Barrier Reef?

While Box Jellyfish and Irukandji can be found in coastal waters, they are extremely rare on the outer reef — where most of our snorkelling and scuba diving tours operate. Outer reef conditions are deeper, more open, and less favourable to stingers, making them a safer environment for water activities.

📅 When is Marine Stinger Season?

Stinger season in Tropical North Queensland typically runs from November to May. During this time, our tours include full safety precautions to ensure all guests enjoy a worry-free experience.
