Marine sting first aid helps keep Australia’s beaches safe. Every year, millions of people swim, surf, and explore our stunning coastal areas, but the ocean is home to some dangerous animals that can deliver painful stings and bites. A quick trip to the beach can turn into a medical emergency if you encounter the wrong creature. Most attacks are painful, but harmless, while others can be life-threatening. All are treatable with marine sting first aid.
General Marine Sting First Aid
In any emergency, your first step should always be to call triple zero, and marine sting first aid is no different. Australia’s waters are full of venomous sea creatures, so if you’re not sure about the kind of creature which stung you treat it as serious. When in doubt, always err on the side of caution. Calling emergency services goes double for particularly large stings or pain which persists several days past the sting.
While waiting for professional medical help to arrive, keep the person calm and still while monitoring their condition and be prepared to start CPR if they lose consciousness.
Jellyfish Stings
Australia is home to many jellyfish species, from the relatively harmless to some of the most dangerous marine animals on Earth. The severity of a sting depends on the jellyfish species, the length of tentacle contact, and how much skin is affected. More tentacle contact means more venom.
Tropical Australian waters are home to the world’s most dangerous jellyfish. The risk is highest during stinger season from October to May. For any jellyfish sting marine sting first aid involves:
Pour vinegar over the sting area to deactivate the sting cells
If vinegar is unavailable, wash the area with seawater. Do not use freshwater as they can activate sting cells.
Carefully remove any remaining tentacles using tweezers.
Apply a cold pack to the area or soak the area in warm water to ease the pain, but only after cleaning it with seawater.
Bluebottle Stings
Bluebottles are not jellyfish, they are bright blue floats shaped like a small balloon with long stinging tentacles. Their stings are among the most common and the most painful on Australian beaches, causing immediate severe pain that feels like a sharp burning sensation and red welts. The pain usually fades within one to two hours, but the skin may stay red and irritated for several days.
The marine sting first aid treatment for bluebottles is straightforward, all you need to do is:
Remove any remaining tentacles from the skin using tweezers.
Rinse the sting site with seawater to wash away any remaining stinging cells. Do not use fresh water, as this can cause more stinging cells to activate.
Soak the affected area in warm water for 20 minutes. The hot water helps break down the venom and provides significant pain relief.
Contrary to popular belief, vinegar and urine should not be used on bluebottle stings. These can actually make bluebottle stings worse by causing more stinging cells to fire and introduce bacteria into the fresh wound.
Blue-Ringed Octopus
The blue ringed octopus is a small but deadly sea creature found in shallow coastal areas. They are usually 10 to 20 centimetres long and yellow or brown in colour with bright blue rings, hence their names. They are shy creatures that hide during the day and hunt at night, and are most likely to bite only if picked up or handled. Their bites may be painless or feel like a minor pinprick, but their venom is extremely dangerous and can cause paralysis in humans.
Within minutes, the victim may feel numbness around the mouth, tongue, and face. This weakness can spread throughout the body and affect the respiratory system to cause the person to stop breathing, requiring CPR.
After calling for help, marine sting first aid for a blue ringed octopus bite requires:
Keep the person still to slow the spread of venom.
Apply a pressure bandage firmly over the bite site, starting from the fingers or toes and winding upward if the bite is on a limb. The bandage should be tight enough that you cannot easily slide a finger underneath without cutting off circulation.
Use a splint or rigid object to immobilise the limb.
Stonefish Stings
Stonefish look exactly like rocks or coral on the ocean floor. Their bumpy, mottled skin blends perfectly with their surroundings. They have sharp spines along their back which inject venom when pressure is applied, like when people accidentally step on them.
Stonefish stings cause immediate, excruciating pain, severe swelling around the sting site, bleeding from the wound, nausea and vomiting, and weakness. In rare cases, the intense pain can cause confusion, fainting, or shock.
Calling 000 is the most important step in marine sting first aid for stone fish. While waiting for help immerse the stung area in hot water, do not remove an embedded spine, and apply pressure to control bleeding.
Sea Urchin Injuries
Sea urchins live on rocky reefs, in rock pools, and on the ocean floor. Their round bodies are covered in sharp, brittle spines that can easily pierce human skin when stepped on, and worse, they can easily break off and become embedded.
Marine sting first aid for sea urchins is easy. Remove the sting if it is embedded, and soak the affected area in hot water.
Stingrays
Stingrays are found in all Australian waters, both coastal and fresh. They rest on the bottom in shallow water, often buried under a thin layer of sand causing people to accidentally step on them. In response, the startled stingray whips its tail upward, driving the barb into the person’s skin
Marine sting first aid for stingrays involves removing an immediate barb fragments before soaking the area in hot water.
Prevention Against Marine Stingers
The best form of marine sting first aid is to avoid them in the first place. Wear full body Lycra suits when swimming in tropical waters during stinger season, and thick soled reef shoes or sturdy sandals when wading in shallow water. The Stingray Shuffle also helps when walking in shallow water; shuffling your feet along the bottom instead of taking normal steps gives stingrays and other creatures warning that you are coming.
Pay attention to beach signs and lifeguard warnings and always swim at patrolled beaches between the red and yellow flags whenever possible. Finally, never touch or pick up any unfamiliar marine life.
