Dangers & Annoyances

Marine Stingers

The potentially deadly Chironex ('sea wasp') and Irukandji box jellyfish, also known as marine stingers, occur in Queensland’s coastal waters north of Agnes Water (and occasionally further south) from around October to April. Swimming near the coast is not advisable during these times. Fortunately, swimming and snorkelling are usually safe around the reef islands throughout the year; however, appearances of the rare and tiny (1cm to 2cm across) Irukandji have been recorded on the outer reef and islands. Check locally or hire a full-body stinger suit.
