Jellyfish are an active part of the NT ocean environment.

Chironex fleckeri is a sea animal, also known as the major box jellyfish. It has the most rapidly acting venom known to science and is capable of killing a person in under 5 minutes.

Current situation

It is now stinger season in the Northern Territory (NT).

Venomous box jellyfish are more likely to be in the water from October up until the end of May.

Territorians and visitors must be highly vigilant around coastal waters as the box jellyfish can be almost invisible in water. The best advice is to stay out of the sea.

For patrolled beaches in the Northern Territory, go to the surf life saving Australia's beach safe website.
