Business Insurance Requirements for Australian Small Businesses: What Is Mandatory and What You Need

Insurance is both a legal requirement and a critical business risk management tool for Australian small businesses. Get it wrong and you could be trading illegally, personally exposed to six-figure liability claims, or unable to recover from a catastrophic event.

This guide covers what insurance is legally mandatory, what is strongly recommended, and the specific requirements that apply to different types of businesses.

Insurance That Is Legally Mandatory

Workers' Compensation Insurance

Mandatory in all states and territories for any employer with employees.

If you employ anyone — including part-time workers, casuals, and in some states, contractors who are workers for workers' compensation purposes — you must hold a current workers' compensation policy. Operating without workers' compensation insurance while employing workers is a criminal offence.

The workers' compensation system in Australia is state-based. Each state has its own insurer arrangements:

• NSW: icare (State Insurance Regulatory Authority)
• Victoria: WorkSafe Victoria (with agents including Allianz, EML, Gallagher Bassett)
• Queensland: WorkCover Queensland
• SA: ReturnToWorkSA / EML
• WA: WorkCover WA (with private insurers)
• Tasmania: WorkCover Tasmania
• NT/ACT: Respective regulators with private insurers

Your premium is based on your industry classification, payroll, and claims history.

Compulsory Third Party (CTP) Insurance

Mandatory for all registered vehicles. CTP insurance covers liability for personal injury to others if you are involved in a motor vehicle accident.

If your business uses vehicles — company cars, vans, delivery vehicles, utes — CTP insurance is required as part of vehicle registration. This is handled through the vehicle registration system in each state; you cannot register a vehicle without CTP.

Note: CTP covers personal injury only, not property damage. You need separate motor vehicle insurance for property damage and third-party property claims.

Professional Indemnity Insurance (Some Professions)

Professional indemnity insurance is mandatorily required for certain licensed professions, including:

• Lawyers: Required by state law societies as a condition of practising certificate
• Accountants: Required for CPA Australia and Chartered Accountants Australia and New Zealand (CA ANZ) members
• Financial advisers: Required by ASIC as a condition of holding an Australian Financial Services Licence (AFSL)
• Healthcare practitioners: Required by AHPRA-registered practitioners under professional board requirements
• Real estate agents: Required in some states as a condition of licence
• Building practitioners: Required in some states as a condition of builder's licence
• Migration agents: Required by the Office of the Migration Agents Registration Authority (OMARA)

If you hold a professional licence or registration, check the insurance requirements of the relevant regulatory body.

Insurance That Is Strongly Recommended (But Not Mandatory)

Public Liability Insurance

Public liability insurance is not legally mandated for most businesses — but it is effectively essential. It covers your legal liability for:

• Bodily injury or property damage suffered by members of the public as a result of your business activities
• Defence costs if a liability claim is made against you

Who needs it:

• Any business that has customers or visitors on its premises
• Any business that sends workers to customer premises
• Any business that interacts with the public

The cost of a single public liability claim — especially one involving serious personal injury — can be devastating for an uninsured small business. A customer who breaks their arm slipping on a wet floor can pursue a claim that runs to hundreds of thousands of dollars.

Some government contracts, leases, and trade association memberships require public liability coverage as a condition.

Typical coverage amounts: $5 million, $10 million, or $20 million for small businesses. The appropriate amount depends on your risk profile.

Product Liability Insurance

If your business manufactures, imports, sells, or supplies goods, product liability insurance covers claims arising from those products causing injury or damage. This is often included in a combined public and product liability policy.

Under the Australian Consumer Law, suppliers and manufacturers can be held liable for defective goods that cause harm, even without negligence in some circumstances.

Professional Indemnity Insurance (Where Not Mandatory)

Even where professional indemnity insurance is not a legal requirement, it is strongly recommended for any business providing professional advice or services — consultants, IT professionals, marketing agencies, architects, and engineers.

Professional indemnity covers claims that your advice, service, or design was negligent or deficient and caused financial loss to the client.

Business Interruption Insurance

Business interruption insurance covers loss of income if your business is unable to operate following an insured event (fire, flood, equipment failure). This is separate from property insurance (which covers the physical loss) — business interruption covers the ongoing financial impact while you rebuild or recover.

For small businesses, a significant disruption to operations can be financially ruinous without business interruption cover.

Cyber Insurance

As businesses become increasingly dependent on digital systems, cyber insurance is growing in importance. It covers:

• Costs of responding to a cyber incident or data breach
• Loss of business income during recovery
• Costs of notifying affected individuals (as required under the Notifiable Data Breaches scheme)
• Legal costs of defending privacy-related claims

Cyber insurance is becoming increasingly important for businesses that hold significant customer data or that are heavily dependent on digital systems.

Industry-Specific Mandatory Insurance

Some industries have specific insurance requirements beyond workers' compensation and CTP:

Construction: Most states require builders to hold home warranty insurance (also called home building compensation insurance) for residential construction projects above specified values. This is a consumer protection — the insurance covers the homeowner if the builder dies, disappears, or becomes insolvent.

Transport: Commercial vehicle operators typically need transport and cargo insurance beyond CTP. Heavy vehicle operations have specific insurance requirements under state transport legislation.

Aviation: Aircraft operators must hold aviation liability insurance as a condition of operating in controlled airspace.

Marine: Recreational vessel operators in some states require third-party liability insurance. Commercial marine operators have specific requirements.

Food businesses: Some local councils and state health authorities require food businesses to hold liability insurance as a condition of a food business licence.

Healthcare: In addition to professional indemnity, some healthcare organisations require clinical liability insurance covering vicarious liability for employed practitioners.

Common Gaps in Small Business Insurance

Underinsurance

The most common insurance problem for small businesses is underinsurance — the sum insured is less than the actual value of assets or the actual cost of claims. Underinsurance means that in the event of a total loss, you cannot fully recover.

Review your sum insured amounts regularly — at least annually — to ensure they reflect current replacement values, not original purchase prices.

No Income Protection for Sole Traders

Sole traders do not get sick leave. If a sole trader is unable to work due to illness or injury, their business income stops. Income protection insurance — covering a portion of your income if you are unable to work — is not covered by workers' compensation for owner-operators and requires a separate policy.

Gaps in Commercial Property Cover

Standard commercial property policies may exclude or limit cover for:

• Flood (particularly relevant in northern Australia)
• Machinery breakdown
• Equipment in transit
• Goods stored at third-party locations

Read your policy carefully and ensure your specific exposures are covered.
