How many first aiders do I need in my workplace?

Under the Safe Work Australia Model Code of Practice, low-risk workplaces need 1 first aider per 50 workers, high-risk workplaces need 1 per 25 workers, and remote high-risk workplaces need 1 per 10 workers. All workplaces need at least 1 first aider.

How many first aid kits does my workplace need?

Every Australian workplace must have at least one first aid kit. Additional kits are recommended based on the number of workers, physical size of the premises, and the types of hazards present. A general guide is one kit per 25 workers for high-risk or one per 50 for low-risk workplaces.

What qualifications do first aiders need in Australia?

First aiders must hold HLTAID011 Provide First Aid (valid for 3 years) and HLTAID009 Provide CPR (annual refresh required). These are nationally recognised qualifications under the Australian Qualifications Framework.

How the Calculator Works

This calculator uses the official first-aider ratios from the Safe Work Australia Model Code of Practice: First Aid in the Workplace (July 2019), adopted by all Australian states and territories.

The ratios are based on three risk categories:

Risk Level	Ratio	Example Workplaces
Low Risk	1 first aider per 50 workers	Offices, retail, libraries, call centres
High Risk	1 first aider per 25 workers	Factories, construction, agriculture, mining
Remote High Risk	1 first aider per 10 workers	Remote mining, outback stations, isolated sites

Every workplace must have at least 1 trained first aider, regardless of size. The calculator also estimates the number of kits recommended based on the same ratios and recommends whether a dedicated first aid room is needed.

What Should Be in a Workplace First Aid Kit?

While kit contents are guidance-based (not prescribed as a fixed list) in all Australian states, the Model Code of Practice provides a suggested minimum contents list. A typical workplace first aid kit should include:

Adhesive dressing strips (plasters) — assorted sizes
Sterile gauze pads and non-adherent wound dressings
Conforming bandages (5cm and 7.5cm widths)
Triangular bandages
Elastic crepe bandages
Wound closure strips (butterfly strips)
Antiseptic solution or wipes
Disposable nitrile gloves
Resuscitation face mask/shield
Scissors, tweezers, and safety pins
Instant cold packs
Eye pads and saline eye wash
First aid guidance leaflet or instructions

High-risk workplaces may also need burns dressings, splints, heavy-duty bandages, and additional quantities. Browse our 220+ kit templates for pre-configured kits suited to your industry.

First Aid Kit Inspection Requirements

All Australian states recommend quarterly inspections (every 90 days) as a minimum. During each inspection you should:

Check all items are present and in sufficient quantity
Check expiry dates on all perishable items (antiseptics, medications, saline)
Replace any used, damaged, or expired items
Ensure the kit is clean, accessible, and clearly labelled
Record the inspection date, inspector name, and any actions taken

FirstAidLog automates this entire process — track expiry dates, schedule inspections, and generate audit-ready reports.

First Aid Requirements by State

While requirements are largely harmonised across Australia under the Model WHS Act, each state has its own regulator and Code of Practice. Select your state for detailed requirements:
