A first aid kit isn’t there to cover every possibility. It’s there to stabilise the handful of things that actually go wrong on Australian tracks, most of them minor, before they turn into something that ends the hike or triggers a rescue. Blisters, cuts, strains, heat stress and the occasional allergic reaction cover most of it. Fractures, snake bite and serious dehydration are rarer, but they’re the reason a kit needs to go beyond bandaids. Size isn’t the point. Knowing why each item is in there is.
Wounds
Cuts and abrasions happen on rocky or scrubby track more often than people expect, and the goal is straightforward: clean it, stop the bleeding, keep it protected from infection while you’re still hours from a shower.
- Compression or roller bandage, for securing dressings or supporting a sprain
- Sterile gauze pads
- Adhesive dressings in a few sizes
- Saline solution, for irrigating a wound or flushing grit out of an eye
- Antiseptic
Clean it properly the first time and check it later in the day. Most wound problems on trail come from someone deciding it’s fine and not looking at it again.
Blisters
More hikes get cut short by blisters than by almost anything else, which makes this the category worth taking seriously even though it feels minor. Hydrocolloid patches or blister dressings, some leukotape or similar friction tape, and small scissors to cut it cleanly. I’ve covered how blisters actually form and how to treat them properly elsewhere, because understanding the mechanism changes what you pack. Taping a hot spot before it blisters is a different job to treating one that’s already open, and the kit needs to support both.
Sprains, strains and snake bite
Uneven terrain means ankles and knees take the load, and what you’re carrying here is really about buying time: enough support to either keep moving safely or stay put and wait it out. An elastic compression bandage and a triangular bandage for a sling or improvised immobilisation cover most of that.
The one item in this category that matters more than its size suggests is a pressure immobilisation bandage: the same broad elastic bandage used for sprains, but long and wide enough (roughly 10cm wide and 10m long) to wrap a full limb. In Australia it’s the standard response to snake bite, and it only works if you actually know the technique before you need it. Since the same bandage does double duty, it’s worth carrying two if you’re heading well away from roads. A remote area first aid course is the difference between having the bandage and being able to use it under pressure. More on what snake bite actually involves, and doesn’t, here.
Allergic reactions and bites
Warmer months bring more of these. Antihistamine for a mild reaction, something topical for itch and irritation. If anyone in the group has a known severe allergy, their adrenaline auto-injector needs to be on them, not buried in someone else’s pack, and everyone in the group should know where it is.
Pain relief and medication
Paracetamol or ibuprofen at sensible doses, and electrolyte replacement if heat and sweat loss are likely to be a factor. Pain relief has a real place here: it can be what gets someone walking out steadily instead of deteriorating from fatigue and discomfort compounding each other. It’s not a fix for whatever’s actually causing the pain, and it shouldn’t be used to push through something that needs to be looked at properly.
Tools and notes
Disposable gloves are useful for treating a wound hygienically, a few small plastic bags are worth having for rubbish or keeping something dry, and hand sanitiser takes up almost no space. Tweezers for a splinter or a tick, small scissors for tape and dressings, and something to write with round things out. A notepad sounds like an odd thing to carry in a first aid kit, but if a situation does escalate, being able to tell paramedics exactly when symptoms started and what’s already been given matters more than people expect.
Personal medication
Whatever you’re already taking, asthma inhalers, insulin, cardiac medication, comes with you in its original labelled packaging, with enough spare for a delay. This is the one category where there’s no substitute and no judgement call. If you take it at home, it goes in the kit.
For extended trips into remote areas, it’s worth asking your GP about medication suited specifically to that kind of trip, such as an adrenaline auto-injector, antihistamines, antibiotics for an infection, or something for severe diarrhoea. These aren’t things most people carry for a day walk, but they’re worth having when professional help is genuinely hours or days away.
It’s worth knowing the legal position too. Only someone medically qualified can give another person a prescription medication; you can’t hand someone your own antibiotics or your own auto-injector, even with good intentions. Helping someone take their own prescribed medication, or offering an appropriate over-the-counter option such as paracetamol from the kit, is fine if they ask for it.

On extended trips into remote areas, a shared kit carried by one or two people can add the bulkier items you’d rarely need but want available if something serious happens: a spare triangular bandage, an extra pressure immobilisation bandage, and a resuscitation mask or face shield for CPR.
What doesn’t belong in it
A personal locator beacon, fire starters, anything closer to survival gear than medical treatment, keep those in the rest of your kit. A first aid kit that’s been padded out with communication or survival gear stops being something you can find things in quickly, and speed is often the whole point.
The kit is only as good as what you know
The most useful thing in a first aid kit isn’t in it. A wilderness or remote area first aid course changes how you actually assess a situation and decide what to do first, and without that, a well-stocked kit is mostly dead weight. Someone who understands bleeding control, pressure immobilisation, heat illness and hypothermia can often improvise past a gap in their gear. Someone who’s only ever carried the kit usually can’t.
Build the kit to match the trip. A day walk doesn’t need what a multi-day alpine crossing needs, and remoteness and group size change what’s worth carrying too. Check it before you go and replace what you’ve used straight after, not next time you remember.
On extended trips into remote country, it can help to think of this as two kits rather than one. Everyone carries their own personal kit: blister care, cuts and bleeding basics, and their own medication, so a single lost or misplaced pack doesn’t leave the whole group without first aid. The bulkier shared items are worth carrying too; see the kit list above. It’s also worth checking whether you have ambulance cover before you go, particularly for anything remote — search and rescue in Australia covers what that cover does and doesn’t help with once you’re actually calling for help.
Even a well-built kit is useless sitting in the boot. A simple pre-hike checklist fixes that, not through rigidity, just consistency when you’re rushing to leave. If you use one, put the first aid kit on it as non-negotiable. There’s a downloadable first aid checklist as part of the hiking preparation and safety checklists here.
A first aid kit is only useful if you understand every item in it and it actually makes it out of the car. Build it around what’s realistic for the trip, not what’s in a generic pre-packed kit, and back it with training so the kit is a resource you can use rather than one you’re hoping never to open.
What’s the most unexpected injury you’ve dealt with on the trail, and how did you handle it?
I came close to blowing out a knee on a walk planned by others and changed mid-route.
Really serious pain over a 200M+ elev descent – steep all the way.
.
It did not become an injury because I recognised early and mitigated by turning and walking backwards as often as possible.
This changed the mechanics in the worst places and allowed me to walk out – limping and in pain.
.
Even so, that left me with 2.5k and another 200M of descent to bear the pain – An injury deflected is far better than the alternative – listen to your body early and know what you expect of yourself and the walk.
.
I was prepared for a 10K steepish walk I had mostly done before – ( solo walked ) – changes that occur on group walks can be very unexpected and sometimes “not the best”.
.
The other take-away is having your own route plan and being self-sufficient even when with a group. I guess I relaxed and “trusted too much” on that day when walking with a recognised group.
Peter Dohnt Ouch, that sounds like a rough day. Walking backwards down a steep descent for 2.5k takes some serious grit. The bit about trusting the group too much is something a lot of people don’t realise until it happens to them. Glad you got home. Thanks heaps for sharing. Lots to learn in that.
