What Should Be in a Spider Bite First Aid Kit? The Australian Guide

Reviewed: 17 April 2026

Walk into any supermarket or pharmacy and pick up a standard first aid kit. Chances are it will include bandaids, antiseptic wipes, a few gauze pads, and possibly some latex gloves. What it almost certainly will not include is the one thing you actually need for an Australian venomous spider bite — a broad elasticised pressure bandage for a funnel-web bite, or an instant ice pack for a redback bite.

Most generic first aid kits were not designed with Australian venomous bites in mind. And because the two most clinically significant spiders in Australia require opposite responses, a kit that covers one scenario may actively cause harm in the other. This guide covers exactly what should be in a spider bite first aid kit, what each item does, and how to check whether your current kit is actually equipped for Australian conditions.

What Australians Need to Know About Spider Bite Kit Contents

The critical insight for any Australian household is this: the contents required for a funnel-web bite and the contents required for a redback bite are different — and in the case of the pressure bandage, using the wrong item on the wrong bite makes things worse, not better.

This is not a problem with generic kits that include a compression bandage but no ice pack — because that kit is appropriate for funnel-web but wrong for redback. Nor is it a problem with kits that include an ice pack but no pressure bandage. The only kit that covers both scenarios is one that was designed specifically for Australian venomous bites and includes both.

Essential Kit Contents for a Funnel-Web Spider Bite

Funnel-web venom spreads through the lymphatic system. The goal of first aid is to slow that spread through compression and immobilisation, buying time for antivenom to be administered at hospital. Every item below serves that single purpose.

1. Broad Elasticised Pressure Bandage (10–15 cm wide)

This is the most critical item for a funnel-web bite. An elasticised bandage — not a crepe bandage, not a triangular bandage — provides the firm, even compression needed to slow lymphatic flow. The bandage must be 10–15 cm wide and applied as firmly as one would apply for a sprained ankle. You should not be able to easily slide a finger underneath it.

Dedicated snake and spider bite bandages with built-in tension indicators are significantly more reliable than standard elastic bandages — the indicators change shape to confirm that correct compression has been achieved, removing the guesswork from a pressure-sensitive technique.

ANZCOR Guideline 9.4.2 is explicit: do not use a crepe bandage if an elasticised bandage is available. Do not use a triangular bandage as a substitute for compression. If nothing else is available, improvise with torn clothing — but the elasticised bandage purpose-built for pressure immobilisation is the correct tool.

2. Rigid Splint

Immobilising the affected limb is as important as applying the pressure bandage. The lymphatic system relies on muscle movement to transport fluid through the body — including venom. A splint that prevents joint movement dramatically reduces the rate of venom spread. In the field, any rigid object can serve as a splint: a straight stick, a rolled magazine, a piece of timber, a tent pole. In a purpose-built kit, a padded rigid splint is included for exactly this purpose.

3. Permanent Marker

Marking the bite site on the outside of the bandage — along with the time of the bite and the time the bandage was applied — is an ANZCOR-recommended step that is frequently overlooked. This information is critical for the treating team at hospital. A waterproof marker should live in every snake and spider bite kit.

4. Scissors

Clothing should not be removed before bandaging — removal increases limb movement and venom spread. But medical scissors allow clothing to be cut away once the bandage is in place, giving hospital staff access to the bite site without disturbing the bandage.

Essential Kit Contents for a Redback Spider Bite

Redback venom acts locally and spreads slowly. The first aid goal is pain management and preventing unnecessary complication while the person reaches medical care. The kit contents required are simpler — but no less important.

1. Instant Ice Pack

An instant ice pack — the kind activated by squeezing — is the primary first aid item for a redback bite. It reduces localised pain and swelling at the bite site. It should be applied to the area directly without excessive pressure. A standard ice pack from a freezer works equally well, but an instant ice pack requires no refrigeration and is ideal for car kits, outdoor kits, and remote travel.

2. Poisons Information Centre Number: 13 11 26

Not strictly a physical kit item, but an essential resource that should be saved in every household member's phone. The Australian Poisons Information Centre operates 24 hours, 7 days a week and can provide immediate guidance on redback bite management — including whether the severity warrants a call to 000. Save it now.

3. Standard Wound Care

Antiseptic wipes, gauze, and dressings are appropriate for basic wound care at the bite site after the ice pack has been applied. These are standard inclusions in most first aid kits and do not need to be spider-specific.

Kit Contents at a Glance — Redback vs Funnel-Web

What to Look for When Choosing a Spider Bite Kit

Not all kits marketed as snake and spider bite kits are equal. When evaluating a kit, check for these specific inclusions:

• An elasticised bandage — not just a crepe bandage. Crepe bandages do not provide sufficient compression for pressure immobilisation technique. Look specifically for an elasticised roller bandage, ideally 10–15 cm wide with tension indicators.
• An instant ice pack. Not an ice spray or a gel pack — an instant chemical ice pack that activates without refrigeration and can be stored in a hot car or outdoor kit without losing effectiveness.
• A splint — or the means to improvise one. Some kits include a padded rigid splint. Others include a SAM splint. Both are appropriate. The splint must be long enough to immobilise the joints above and below the bite site.
• A permanent marker. Sounds trivial. Frequently missing from generic kits. It is an ANZCOR-specified step.
• Packed in Australia for Australian conditions. Generic imported kits are often configured for climates and hazards that are not relevant to Australia.

A first aid kit is only as useful as what is inside it. For Australian spider bites, the contents matter — and the knowledge of which item to reach for matters just as much.
