Blue-Ringed Octopus

The blue-ringed octopus is a beautiful, but deadly creature which can be found in rock pools and shallow reefs all around Australia.

Despite its small size, the blue-ringed octopus carries enough venom to kill 26 adult humans within minutes. The venom is in their saliva and enters your system when they bite you. Their bite can result in paralysis and respiratory depression – stopping you from breathing.

When exploring rock pools, look but don’t touch.  In the event of a suspected bite, seek immediate medical attention.

Bluebottle on the sand;


The bluebottle (physalia) is probably the most well known marine stinger found around the Australian coastline.

How to treat a sting:

  1. Wash off any remaining tentacles with sea water (not freshwater)
  2. Immerse the patient’s sting in hot water – no hotter than can be easily tolerated for 20 minutes
  3. If the pain is unrelieved by heat, or if hot water is not available, apply cold packs or ice in a dry plastic bag
  4. Refer to medical aid for further treatment if symptoms persist.
Shark underwater;


There are many species of sharks around Australia. Most are harmless to humans. Although humans fear sharks, they are an important part of the ecosystem and a reality of the ocean.

Tips to minimise a shark encounter:

  • Swim at a patrolled location between the red and yellow flags
  • Avoid swimming and surfing at dawn, dusk and night
  • Avoid swimming at river mouths or in murky, discoloured waters
  • Avoid swimming in or around schools of baitfish
