Does your kit cover both a redback and a funnel-web bite?
These two spiders need opposite first aid responses — and opposite kit contents. Every Assurance snake and spider kit is packed in Dubbo with clinical-grade supplies for Australian conditions.

Funnel-web bite: Apply a pressure immobilisation bandage immediately. Call 000.
Redback bite: Do NOT apply a pressure bandage. Apply ice. Seek medical attention.
Getting this wrong does not just fail to help — it can actively make the situation worse.
Here is something that surprises most Australians: the first aid treatment for a redback spider bite is the opposite of what you do for a funnel-web bite. Apply a pressure immobilisation bandage to a redback bite and you could concentrate the venom, intensify localised pain, and cause unnecessary tissue damage.
This is one of the most common first aid mistakes made in Australia — and it is completely understandable, because "spider bite" sounds like one problem with one solution. It is not. The two most clinically significant spiders in Australia have venoms that work in entirely different ways, travel through the body differently, and require opposite responses.
This guide explains why — and gives you the exact steps for both, based on ANZCOR Guideline 9.4.2.
What Australians Need to Know About Spider Bite First Aid
Australia is home to over 10,000 species of spiders, but two dominate emergency department presentations: the funnel-web and the redback. Both are venomous. Both are found in and around Australian homes. But their venoms work completely differently — and that difference is what determines the correct first aid response.
Know Your Local Risk — Where Each Spider Is Found
| Spider | Primary Habitat | Most Common In |
|---|---|---|
| Redback | Dry, sheltered spots — letterboxes, outdoor furniture, garden sheds, play equipment, outdoor toilets | Every state and territory — especially inland and warmer, drier regions. Very common in Dubbo, Broken Hill, Bourke and regional NSW. |
| Funnel-Web | Cool, moist environments — gardens, woodpiles, pool filter boxes, shoes, sheds | East coast — greater Sydney, Blue Mountains, Central Coast, Hunter Region, southern highlands, south-east Queensland |
If you live in inland or regional NSW, your primary spider bite risk is redback. If you live on the east coast or travel there regularly, funnel-web risk is real. Across Australia — prepare for both.
How the Venoms Work Differently
Understanding why the treatments differ starts with understanding how each venom behaves in the body.
Funnel-web venom contains delta-atracotoxin — a neurotoxin that attacks the nervous system rapidly. It spreads through the lymphatic system, which means movement dramatically accelerates its effect through the body. Pressure immobilisation slows lymphatic flow and buys critical time for antivenom to be administered at hospital.
Redback venom contains alpha-latrotoxin, which causes a syndrome called latrodectism. The venom acts locally and spreads slowly — it does not travel rapidly through the lymphatic system. Applying a pressure bandage over a redback bite does not slow anything useful. Instead, it concentrates the venom at the bite site, intensifies localised pain, and restricts circulation unnecessarily.
What the Research Says
The Australian Venom Research Unit at the University of Melbourne specifically advises against pressure immobilisation for redback bites. The NSW Health Emergency Care Institute confirms that a pressure bandage will make redback bite pain worse and is not recommended. ANZCOR Guideline 9.4.2 is clear: ice only for redback bites, pressure immobilisation for funnel-web bites.
First Aid Steps — Funnel-Web Spider Bite — As per ANZCOR Guideline 9.4.2
- Call 000 immediately. Do not wait for symptoms. Life-threatening effects can occur within 10 minutes.
- Keep the person completely still. Do not allow them to walk. Lay them down. Movement spreads venom through the lymphatic system.
- Apply a pressure immobilisation bandage — a broad elasticised bandage (10–15 cm wide) — directly over the bite site, then extend it from the fingers or toes up the entire limb. As firm as a bandage for a sprained ankle.
- Mark the bite site on the outside of the bandage with a pen. Note the time of the bite and when the bandage was applied.
- Immobilise the limb with a splint — any rigid object — to prevent joint movement.
- Do not remove the bandage until the person is at hospital with antivenom available.
- Do not wash, cut, or suck the bite site. Do not apply a tourniquet. Do not try to catch the spider — a phone photo is enough.
- Monitor breathing. Be ready to perform CPR if the person becomes unresponsive and is not breathing normally.
First Aid Steps — Redback Spider Bite — As per ANZCOR Guideline 9.4.2
- Do NOT apply a pressure immobilisation bandage. This will concentrate the venom and worsen pain.
- Apply an ice pack or cold compress to the bite site to reduce pain.
- Keep the person calm and rested.
- Seek medical attention — redback antivenom is available and effective.
- Call the Poisons Information Centre: 13 11 26 if unsure of severity. Available 24/7 across Australia.
- Call 000 if symptoms worsen rapidly — particularly in children, the elderly, or anyone with underlying health conditions.
Not Sure Which Spider Bit You?
Call the Poisons Information Centre on 13 11 26 immediately — available 24 hours, 7 days across Australia. If symptoms are progressing rapidly — sweating, muscle twitching, difficulty breathing — call 000 and treat as a funnel-web bite until confirmed otherwise.
How to Apply the Pressure Immobilisation Bandage Correctly
The technique matters as much as the decision to use it. Research from the Australian Venom Research Unit shows that pressure immobilisation bandages applied in the field are frequently too loose to be effective. Samantha demonstrates the correct technique below — filmed as a snake bite bandage, but the pressure immobilisation method is identical for funnel-web spider bites.

| Symptom | Funnel-Web Bite | Redback Bite |
|---|---|---|
| Initial pain | Severe and immediate | Mild at first, worsens over time |
| Sweating | Profuse, rapid onset | Localised sweating at bite site |
| Muscle twitching | Yes — rapid onset | Rare |
| Nausea / vomiting | Common and rapid | Can occur but slower onset |
| Breathing difficulty | Can develop within 30 minutes | Uncommon unless severe reaction |
| Timeline to serious symptoms | 10 – 30 minutes | 1 – 3 hours |
| Correct first aid | Pressure bandage + 000 | Ice pack + medical attention |
A Note on Neurodiverse Children
For parents of autistic children or children with sensory processing differences, spider bite first aid brings an additional challenge — a child in sensory overload may not be able to tolerate the pressure bandage, may not communicate where the pain is, or may become so distressed that treatment becomes nearly impossible.
We have written a dedicated guide for this: Snake Bite First Aid for Neurodiverse Kids: A Step-by-Step Guide — with sensory regulation strategies and neurodiverse-adapted bandaging technique embedded at every step.
We also strongly recommend keeping a completed All About Me emergency card in your first aid kit, so any first responder knows exactly what your child needs.
Which Kit Covers Both Scenarios?
A funnel-web bite needs a compression bandage. A redback bite needs an ice pack. Most generic kits include only one — or neither. Here is what each Assurance kit covers.

Frequently Asked Questions
Can you use a pressure bandage on any spider bite in Australia?
No. Pressure immobilisation bandages are recommended for funnel-web spider bites and snake bites only — not for redback bites. Applying a compression bandage to a redback bite concentrates the venom locally and increases pain significantly. Always identify the spider if it is safe to do so, or call 13 11 26 for guidance.
What should I do if I am not sure which spider bit me?
Call the Poisons Information Centre on 13 11 26 immediately. Describe the spider, the bite site, and any symptoms. If symptoms are progressing rapidly — sweating, muscle twitching, difficulty breathing — call 000 and treat as a funnel-web bite until confirmed otherwise. A phone photo of the spider is useful but should never delay calling for help.
Are redback spider bites dangerous?
Redback bites are painful and can cause latrodectism — a syndrome involving sweating, nausea, and intense localised pain. Antivenom is available and effective. Deaths from redback bites are extremely rare, but medical attention is always recommended — particularly for children and elderly individuals.
How do I identify a redback spider?
Redback spiders are small and black with a distinctive red or orange stripe on the upper abdomen. Females are larger and more venomous than males. They build irregular, sticky webs in dry, sheltered locations — under outdoor furniture, in letterboxes, garden sheds, and children's play equipment. They are extremely common in inland and regional Australia.
Do I need a different first aid kit for funnel-webs and redbacks?
Your kit ideally includes both a compression bandage for funnel-web and snake bites, and an ice pack for redback bites. The Assurance Snake Bite Max Kit, Family First Aid Kit, and 4WD Outdoor Kit all include both. If you live in a high-risk funnel-web area, make sure every vehicle and building on your property has a kit with a pressure bandage in it.
Is the bandage technique the same for snake bites and funnel-web spider bites?
Yes — the pressure immobilisation technique is identical. Both venoms spread through the lymphatic system and both require the same compression and immobilisation approach. The videos on this page demonstrate the technique for snake bite — the method is exactly the same for funnel-web bites.
The Right Kit for the Right Bite
Spider bites are not a one-size-fits-all emergency. The two most dangerous spiders in Australia require opposite first aid responses — and that means your kit needs to be equipped for both scenarios.
Samantha suggests one of the following — choose what suits your audience best:
Option A — Direct Product
If you live along the east coast or spend time outdoors in Australia, make sure your kit covers both a compression bandage and an ice pack. The Assurance Family First Aid Kit has both — packed locally in Dubbo, ready to go.
Shop the Family Kit →Option B — Kit Finder
Not sure which kit suits your home, vehicle, or next outdoor trip? Answer three quick questions and we'll match you with the right one — packed in Australia for real Australian conditions.
Find My Kit →Option C — Urgency
You cannot treat a redback bite with a funnel-web kit. Every Australian home, vehicle, and daypack should be equipped for both. Don't guess — get the right gear now.
