What is workers’ compensation insurance?

Workers’ compensation insurance is compulsory cover for work-related injury or illness, managed by each state and territory in Australia. The goal is to support injured workers and protect employers from uninsured costs when an employee suffers a workplace injury or develops a work-related illness.

Each state and territory runs its own scheme, which means eligibility, benefits, and processes differ by jurisdiction. For example, workers’ compensation NSW operates under the icare NSW scheme, while Victoria uses WorkSafe Victoria. Understanding which scheme applies to your business depends on where your employees work, not where your business is registered.

The system ensures injured workers receive medical expenses coverage, lost wages replacement, and rehabilitation support. At the same time, it caps your liability as an employer, so you're not exposed to unlimited costs if something goes wrong. This balance makes workers’ compensation insurance in Australia a cornerstone of workplace safety and financial protection.

Who needs workers’ compensation insurance in Australia?

Most employers with full-time, part-time, or casual staff in the state where they work must hold a workers’ compensation insurance policy. This applies whether you have 1 employee or 100. The obligation kicks in from the moment you pay wages, so set up cover before or as you start to pay your first worker.

Use payroll data to identify where each worker operates so you register them under the correct state workers’ compensation scheme in Australia. For instance, if you employ someone in New South Wales, you'll need to register with icare NSW for workers’ compensation cover.

Do contractors count as workers?

Contractors may be deemed workers if they're paid mainly for labour, integrated into your business, or controlled like employees. Apprentices and trainees are generally treated as workers under most schemes. Labour hire workers are usually covered by the labour hire employer, not the client business.

Directors and sole traders are not always covered and may need optional cover under the relevant scheme. Check with your state insurer or the ATO's guidance on employee or contractor status to clarify your obligations. This distinction matters because misclassifying workers can lead to fines and uncovered claims.

What does workers’ compensation insurance cover?

Workers’ compensation insurance typically covers wage replacement, medical and hospital treatment, rehabilitation and return-to-work support, and disability benefits or lump-sum payments for permanent impairment. If an employee dies from a work-related injury or illness, the policy may also provide death benefits to dependents.

Common exclusions include non-work-related injuries, serious and wilful misconduct, or injuries outside the course of employment. For example, if an employee is injured during their lunch break off-site, the claim may not be covered. Policy terms differ by state, so check your scheme's scope and limits.

How does workers’ compensation differ from public liability insurance?

Workers’ compensation supports employees injured at work, while public liability and workers’ compensation insurance are separate products. Public liability covers third-party injury or property damage caused by your business operations, such as a customer slipping in your store.

Many businesses need both policies. Clients may request proof of public liability and workers’ compensation insurance for contracts or site access. Here’s more about different types of business insurance and what they cover in Australia.

How much does workers’ compensation insurance cost?

Premiums depend on total wages, industry risk classification, claims performance, and state-specific loadings or discounts. High-risk industries like construction typically pay higher rates than low-risk sectors like professional services. Your claims history also matters, as frequent or severe claims can push premiums up.

Keep payroll organised by state, worker type, and classification to avoid large adjustments at renewal. Use state calculators or insurer tools to estimate insurance premium costs before hiring or tendering. For instance, icare NSW offers a premium calculator to help you budget.

How do wage declarations and audits work?

Most schemes require annual actual wage declarations and in-year estimate updates. You'll need to keep payroll reports by state, timesheets, contractor agreements, claims documents, and certificates of currency. Audits focus on correct classifications, included wage items, and accurate state allocations.

If you underestimate wages, you'll face a catch-up premium at renewal. If you overestimate, you may get a refund. Accurate payroll records reduce surprises and help you manage cash flow. For more tips, see payroll compliance.

How do I get workers’ compensation insurance by state?

You register with the scheme where the work is done, then declare wages and pay the assessed premium. Processes vary: some states are underwritten by the government, others by approved insurers. Set up cover before or as you start to pay wages in that state.

For example, if you employ workers in Queensland, register with WorkCover Queensland. If you expand to South Australia, you'll need a separate policy with ReturnToWorkSA. Each scheme has its own registration portal, premium calculator, and compliance requirements.

What information do I need before I register?

Having the right details ready before you start your application makes the registration process straightforward. Most state schemes will ask for the following:

• Your Australian Business Number (ABN): Used to verify your business identity with the scheme.
• Estimated annual wages: Your best estimate of total wages you'll pay in the coming year, including superannuation and some contractor payments.
• Your workers’ compensation industry classification (WIC) code: This identifies the type of work your employees do and affects your premium rate. You can look up your code using your state scheme's online tool.
• Number of workers: The total count of employees you're covering, including full-time, part-time, and casual staff.
• State or territory where work is performed: Each scheme covers workers based on where the work happens, not where your business is registered.

If you employ workers across multiple states, gather this information separately for each jurisdiction before you begin.

Where do I register in my state or territory?

Here's where to register for workers’ compensation insurance across Australia:

• New South Wales: icare NSW
• Victoria: WorkSafe Victoria
• Queensland: WorkCover Queensland
• South Australia: ReturnToWorkSA
• Western Australia: WorkCover WA (approved insurers)
• Tasmania: WorkSafe Tasmania
• Australian Capital Territory: WorkSafe ACT
• Northern Territory: NT WorkSafe
• Commonwealth agencies: Comcare

What are my employer obligations after I get cover?

Keep your policy current in each state where people work and update details when they change. Declare wages accurately and on time to avoid adjustments or penalties. Report injuries promptly and support return to work as part of your workers’ compensation employer obligations.

Keep required records, including wage data, timesheets, contractor agreements, injury reports, and medical certificates. Display required notices and store your certificate of currency where clients can access it. For more information, see employer responsibilities.

How do I get a certificate of currency?

Download or request your certificate from your scheme or insurer once cover is active. Provide it to clients, principal contractors, or site managers before work starts. Set a reminder to renew and refresh the certificate when your policy renews.

Many schemes let you download certificates instantly from your online portal. Keep a digital copy in your business records and email it to clients as needed. This proof of cover is often a contract requirement, especially in construction and trades.

What happens when a worker is injured or ill?

Follow these steps to manage a claim and support your employee:

• Get immediate care and make the worksite safe. Arrange first aid or emergency medical treatment if needed. Your priority is the worker's wellbeing and preventing further incidents at the scene.
• Record the incident and collect details. Note the date, time, location, and witnesses. Take photos if relevant and safe to do so. Document what happened while details are fresh in everyone's memory.
• Notify your insurer or scheme within the required timeframe. Most states require notification within 48 hours, though some give you five days. Check your scheme's specific requirements, as late notification can affect claim processing.
• Provide documents including incident reports, wage details, and medical certificates. Your insurer will guide you on what's needed. Having organised payroll records makes this process smoother and faster.
• Support the return-to-work plan and stay in touch with the insurer and worker. Early return-to-work programs reduce costs and help workers recover faster. Maintain regular contact to show you care about their recovery.

Can I get workers’ compensation for myself as a sole trader?

In most states, sole traders and directors are not automatically covered but can opt in for personal injury insurance under the relevant scheme. Check with your state insurer for eligibility and costs.

What if my employee works remotely or interstate?

Register in the state where the work is performed. If an employee works from home in Victoria, you need WorkSafe Victoria cover. If they move interstate, update your policies accordingly.

How long do I need to keep workers’ compensation records?

Most states require you to keep wage records, claims documents, and certificates of currency for at least 7 years. This aligns with tax record-keeping obligations. For more on record-keeping, see superannuation obligations.

What happens if I don't have workers’ compensation insurance?

Operating without cover can result in fines, prosecution, and unlimited liability for workplace injuries. You may also be ineligible for government contracts and face reputational damage.
