First Aid Requirements Calculator — Kits & Officers

Work out how many first aid kits and trained first aiders your workplace needs based on size, risk level and location under the WHS Code.

Last verified: 21 June 2026

The model Code of Practice recommends, as a guide, 1 first aider per 50 workers (low risk) and 1 per 25 (high risk); high-risk workplaces without timely access to medical or ambulance services should have at least 1 per 10. This tool applies those recommended ratios to your worker count, tells you whether a first aid room is recommended, and gives kit guidance — but these are recommendations, not strict law. The law requires first aid that is adequate for your specific workplace.

Work out your recommended first aid provision

Enter your workplace details to see how many trained first aiders the model Code recommends, whether a first aid room is recommended, and what to put in your kit. These are recommendations, not strict legal requirements.

2. What is your workplace risk level?

Recommended first aid provision

1 recommended first aider

Based on the recommended ratio of 1:50 for low-risk work.

How this is worked out
Your workplace is low risk, so the Code recommends, as a guide, 1 first aider for every 50 workers.
First aid room
A dedicated first aid room is not recommended at this size — the Code suggests one only at 200+ workers for low-risk work. A suitable first aid space or kit area is still expected.
First aid kit
  • Provide at least one well-stocked first aid kit, located where it is easy to find and get to.
  • The Code gives a recommended example kit in Appendix C (adhesive dressings, wound dressings, gauze, gloves, scissors, saline, a resuscitation face shield, and so on) — there is no single fixed legal contents list, so tailor the kit to your workplace's hazards.
  • For lower-risk workplaces an office-style kit is usually enough, but still match the contents to your actual hazards.
  • Mark the kit with a white cross on a green background, and keep contents stocked and in date.
  • Check the kit after each use, and at least every 12 months. In a multi-storey building, provide at least one kit on every second floor.

Model Code of Practice "First aid in the workplace" (Safe Work Australia). First-aider numbers are recommended ratios, not banded worker-count rules; first aid kit contents are the recommended example in Appendix C.

Important: These figures are recommendations from the model Code of Practice, used as a guide — they are not strict legal requirements. The law requires you to provide first aid that is adequate for your specific workplace, having regard to its hazards, size and location. Use your own risk assessment to decide what you actually need.

Victoria and WA: The harmonised model Code applies in the Commonwealth, NSW, QLD, SA, TAS, ACT and NT. Victoria has its own Compliance Code for first aid, and Western Australia has its own first aid code — the ratios are broadly similar but check your own regulator's code.

This is general information, not legal or first aid advice. First aid needs vary with your workplace hazards, size and location. Carry out your own first aid risk assessment and check the current code for your jurisdiction before relying on these figures.
