The complete employer guide to mandatory workers comp requirements, state-by-state rules, premium costs, claims process and how to stay compliant — and save money — in 2026.
Workers compensation insurance is a statutory insurance scheme that protects employees who suffer a work-related injury or illness. It also protects employers from the full cost of these claims.
If you are injured at work or develop a work-related illness, workers compensation entitles you to:
Workers compensation insurance shields your business from potentially catastrophic out-of-pocket liability:
In Australia, workers compensation is administered at the state and territory level. Each jurisdiction has its own legislation, scheme insurer(s) and regulatory authority. There is no single national scheme for private employers, though federal employees are covered under the Safety, Rehabilitation and Compensation Act 1988 (Comcare).
The short answer: every employer in Australia. If you pay wages, you are almost certainly legally required to hold workers compensation insurance. There are no meaningful exemptions for small businesses.
Beyond traditional employees, many workers compensation schemes extend coverage to:
Full-time, part-time and casual employees are always covered.
Always requiredContractors who work substantially for one principal are treated as employees in NSW, QLD and SA.
Check your stateLabour hire agencies are typically the employer of record and must insure placed workers.
Agency's obligationMust be insured by the host employer from day one.
Always requiredIn some states, working directors who receive wages are covered. Others may opt in.
Varies by stateGenerally not covered under workers compensation — separate volunteer insurance applies.

Premiums are calculated as a percentage of your gross wages bill. The rate you pay depends on your industry classification, your claims history and the state you operate in.
| Industry | Approx. Rate (% of Wages) | Risk Level | Example Annual Premium* |
|---|---|---|---|
| Construction & Civil Works | 5% – 8% | Very High | $25,000 – $40,000 |
| Manufacturing & Warehousing | 3% – 5% | High | $15,000 – $25,000 |
| Transport & Logistics | 2.5% – 4% | High | $12,500 – $20,000 |
| Agriculture & Farming | 2% – 4% | High | $10,000 – $20,000 |
| Hospitality & Food Service | 1.5% – 2.5% | Medium | $7,500 – $12,500 |
| Retail Trade | 1% – 2% | Medium | $5,000 – $10,000 |
| Healthcare & Social Assistance | 1% – 2% | Medium | $5,000 – $10,000 |
| Professional Services / Office | 0.5% – 1% | Low | $2,500 – $5,000 |
* Example premiums based on $500,000 annual wages bill. Actual premiums vary significantly by state, insurer and individual claims history.
Your ANZSIC industry code is the single biggest driver. High-risk industries pay higher base rates.
Premiums scale directly with your total wages bill. Accurate wages declarations are essential.
A poor claims history (experience rating) can significantly increase your premium above the base rate.
Documented WHS management systems, regular toolbox talks and proper PPE provision can earn premium discounts.
Getting injured workers back to suitable duties quickly reduces the duration and cost of claims.
Proactive risk assessments and hazard elimination demonstrate to insurers you are managing risk.
The claims process is broadly similar across all states. Prompt action by both the worker and the employer is critical to a smooth outcome.
The injured worker must report the work-related injury or illness to their employer as soon as practicable. In most states there are strict time limits — typically 30 days from the date of injury. Delay can jeopardise the claim.
The employer must record the injury in the workplace register of injuries (required under WHS law) and provide the worker with a workers compensation claim form. You must not discourage workers from claiming.
The worker sees a doctor, who issues a certificate of capacity (sometimes called a medical certificate for workers comp). This document specifies what work the employee can or cannot perform and is central to the claim.
The employer (not the worker) lodges the completed claim form with your workers compensation insurer within the required timeframe — typically 5 to 7 business days of receiving it. Late lodgement may attract penalties.
The insurer investigates the claim and determines whether to accept or dispute liability. This typically takes 7–21 days. If accepted, weekly payments and medical expense reimbursements begin.
As soon as possible, the employer, worker, treating doctor and insurer develop a return-to-work plan. Early return to suitable duties — even modified work — dramatically reduces claim costs and benefits the worker's recovery.
If a claim is disputed, each state has a specific tribunal or commission for resolution — e.g., the Personal Injury Commission in NSW, VCAT in Victoria, or the Workers' Compensation Regulator in QLD. Seek legal advice promptly if a dispute arises.
Workers compensation insurance is just one piece of your legal obligations as an employer. The Work Health and Safety Act 2011 (harmonised across most jurisdictions) places additional duties on every employer.
Under the WHS Act, a person conducting a business or undertaking (PCBU) must ensure, so far as is reasonably practicable, the health and safety of workers and others at the workplace. This includes:
In addition to general WHS duties, specific workers compensation legislation requires employers to:
The financial and legal consequences of operating without workers compensation insurance — or failing to meet WHS obligations — are severe and increasing.
| State | Maximum Fine (Uninsured) | Personal Liability? | Back-Premium Liability? |
|---|---|---|---|
| NSW | $55,000 per offence | Yes | Yes — full claim costs |
| VIC | $109,000+ (1,200 penalty units) | Yes | Yes — full claim costs |
| QLD | $60,000+ | Yes | Yes — full claim costs |
| WA | $50,000+ | Yes | Yes |
| SA | $50,000+ | Yes | Yes |
| TAS / NT / ACT | $25,000 – $50,000+ | Yes | Yes |
Beyond workers compensation non-compliance, breaches of the WHS Act itself carry severe penalties:
Reckless exposure of a person to risk of death or serious injury.
Up to $3 million (company) or $300,000 + 5 years jail (individual)
Failure of a duty that exposes a person to risk of death or serious injury.
Up to $1.5 million (company) or $150,000 (individual)
Failure of a duty without exposure to death or serious injury risk.
Up to $500,000 (company) or $50,000 (individual)
Proper PPE is one of the most tangible ways to reduce workplace injuries — and therefore lower your workers compensation premiums over time. These are our top recommended products for Australian workplaces.
While each state has a mandated scheme insurer or authorised private insurers, you can still compare policies, premium quotes and service quality. For businesses needing additional workers comp cover or operating across multiple states, these comparison platforms can help.
Answers to the most common questions from Australian employers about workers compensation insurance.
Yes. Workers compensation insurance is legally mandatory for all employers in every Australian state and territory. Any business that employs workers — including part-time, casual and some contractors — must hold a valid policy.
Operating without cover can result in fines of up to $109,000 (VIC) and leaves you personally liable for all compensation costs if a worker is injured.
Premiums are calculated as a percentage of your total wages bill. Rates vary by industry:
The national average across all industries is approximately 1.4% of wages. Your individual rate will also be affected by your claims history.
Coverage includes:
Work-related mental health conditions (e.g., workplace stress, bullying) are also covered in all states, though liability thresholds differ.
Yes. In most Australian states, having even one employee triggers the mandatory obligation. Some states have minimum wages thresholds (e.g., WA sets a $7,500 wages threshold before the obligation applies), but as a rule any employer with workers should hold cover from day one.
It depends on the state and the nature of the engagement. In NSW, QLD and SA, "deemed workers" — contractors who perform work substantially for one principal — are treated as employees for workers compensation purposes.
In VIC, a contractor who performs work that is part of the principal's usual business activities may be deemed a worker. Always seek legal advice when engaging contractors, and check your state's specific legislation.
Penalties are severe:
Beyond fines, uninsured employers are personally liable for all compensation costs. If a worker suffers a serious injury and you are uninsured, you could face hundreds of thousands of dollars in claims costs on top of the fines.
