What first aid kit is required on boats in Australian waters?
Short Answer: The answer depends almost entirely on whether the vessel is commercial or recreational. Domestic commercial vessels fall under the National Standard for Commercial Vessels, which scales first aid equipment to the operational area and the number of people on board, so a vessel working well offshore carries considerably more than one confined to smooth inland water. Recreational boating is regulated state by state, and a marine first aid kit is usually recommended rather than mandated, though the distance between a boat and an ambulance makes that recommendation worth treating as a requirement.
Marine kits face conditions no shore-based kit deals with, so before buying one, you also need to consider the following:
• Are there maritime safety regulations to follow?
• What injuries are common during boating activities?
• Should offshore vessels carry advanced trauma modules?
• How can marine kits be protected from moisture damage?

Are there maritime safety regulations to follow?
For commercial operations, yes, and they are more prescriptive than most workplace first aid rules. The Australian Maritime Safety Authority administers domestic commercial vessels under the national marine safety law, with safety equipment requirements sitting in the National Standard for Commercial Vessels. Those requirements are organised by operational area, running from unlimited offshore operation down to smooth waters, with first aid equipment scaling up as the vessel moves further from help. A charter boat operating within partially smooth waters and a fishing vessel working beyond 200 nautical miles are not asked to carry the same thing.
Larger vessels regulated at Commonwealth level carry an additional layer, with medical store requirements set out in the Marine Orders that reach well beyond a standard kit and into prescription medicines held under the master's control. Those obligations rarely touch small operators, but they explain why marine first aid advice online varies so widely depending on which vessel class the writer had in mind.
Recreational boating is a different matter, since safety equipment lists are set by each state or territory rather than nationally. Those mandatory lists focus on flotation and distress signalling, meaning lifejackets, flares and an EPIRB for offshore trips, with first aid kits generally appearing only as a recommendation. Commercial crew are separately covered by work health and safety law, because a crewed vessel is a workplace, so the duty owed to crew sits alongside whatever the marine regulator requires for passengers.
What injuries are common during boating activities?
Lacerations dominate, and they are rarely minor. Fillet knives, fish hooks, winches and unprotected propellers produce deep wounds on a surface that is wet, moving and often crowded. Deck slips account for most of the rest, with wet fibreglass and a rolling swell turning what would be a simple stumble on land into a head injury or a fracture. Crush injuries from mooring lines and heavy hatches round out the mechanical side.
Then there is everything specific to the marine environment. Envenomation changes by latitude, with bluebottle stings common along the east coast and tropical waters bringing box jellyfish and Irukandji into the picture in the warmer months. Treatment differs between them, since vinegar is the accepted first response for tropical jellyfish stings while hot water immersion suits bluebottle stings and stonefish or stingray injuries, which is why a marine kit carries both. Heat exhaustion and severe sunburn appear more often than operators expect, given the glare reflecting off the water.
Burns come from the engine space and the galley rather than open flame, and hydrogel dressings handle most of what occurs on board. Immersion and near-drowning sit at the serious end and demand resuscitation equipment rather than dressings, which is why a pocket mask belongs in any kit carried beyond swimming distance from shore. Seasickness is not an injury, though a crew member incapacitated by it is one fewer pair of hands when something goes wrong.
Should offshore vessels carry advanced trauma modules?
Yes, and the reason is time rather than injury severity. A vessel sixty nautical miles offshore may be hours from definitive care even with a helicopter tasked, so the equipment on board has to hold a patient stable far longer than a shore-based kit ever needs to. Catastrophic bleeding is the clearest case, since a propeller strike or a winch injury can produce arterial bleeding a standard wound dressing will not control. A tourniquet and haemostatic gauze, backed by somebody trained to use both, change the outcome in a way that additional adhesive dressings never will.
Immobilisation equipment matters more at sea than on land because the platform keeps moving. A malleable splint and a means of securing a casualty for transfer are worth carrying, and vessels regularly working offshore often add a rigid stretcher suitable for hoisting. Oxygen therapy is a further step, though it only makes sense where the crew hold the training and the cylinder is serviced on schedule.
Training has to scale with the kit, since equipment nobody can use is weight rather than capability. Units such as HLTAID013 Provide first aid in remote or isolated site suit vessels working beyond quick assistance, and crew should know how to obtain radio medical advice through the rescue coordination centre before they need it. An automated external defibrillator is increasingly carried on larger charter vessels, since a cardiac arrest offshore has no other realistic answer.
How can marine kits be protected from moisture damage?
Salt air is harder on a kit than seawater is, because it works constantly rather than in one event. A sealed hard case with a gasket and a pressure equalisation valve is the sensible base for a permanently mounted kit, while a roll-top dry bag suits a tender or small open boat where the kit moves around. Individually sealed contents matter as much as the outer case, since one wave through a hatch will ruin loose gauze inside a sound container. Desiccant sachets cost almost nothing and are worth replacing annually.
Where the kit lives decides how long it lasts. Above bilge level and out of the engine space is the rule, because heat degrades hydrogel and shortens the life of anything with an adhesive backing, while a lazarette or the void under a bunk collects condensation. Metal instruments corrode quickly here, so marine-grade stainless or polymer shears outlast cheaper alternatives by a wide margin. A buoyant case in a high-visibility colour matters if the vessel takes water.
Furthermore, a special duty is placed on the PCBU to ensure that all first aid kits are routinely inspected and maintained, which applies squarely to charter operators, commercial fishing businesses and dive boats whose crew are workers under the law. Marine conditions shorten effective shelf life, so a check after every extended trip beats a calendar interval. SURVIVALSWAP takes the restocking off the operator, replacing used and expiring items on a managed schedule and keeping a supply record, which is useful when a survey or an audit asks what has been carried and when.

What first aid training should crew hold on a commercial vessel?
The baseline for most crew is HLTAID011 Provide first aid with HLTAID009 Provide cardiopulmonary resuscitation, refreshed every three years and every twelve months respectively. Crew holding a coxswain or master qualification generally complete first aid as part of the certificate itself, with elements of shipboard safety training covering survival and emergency response alongside it. Vessels working further offshore are better served by the remote or isolated site unit, which assumes help is hours rather than minutes away and covers prolonged casualty care. The practical question is not whether somebody holds a certificate but whether enough certificate holders are rostered on every trip, since a single trained crew member who is also the casualty leaves the vessel with nobody. Most operators running multi-day trips train the whole crew for that reason.
Conclusion
Marine first aid comes down to matching the kit to how far you go and how long you would wait. Commercial operators should start from the operational area their vessel is certificated for, and recreational boaters should ignore the fact that a kit is only recommended and carry one regardless. Either way, the sea will find any weakness in how the kit is packaged and stored. SURVIVAL supplies Australian marine first aid kits in sealed, corrosion-resistant cases along with the modules and accessories needed to build up to offshore capability. If you are certificating a new vessel or extending your operational area, review the kit before the survey rather than after it.
