Business insurance is one of those topics where most Australian business owners fall into one of two camps. Either they're underinsured because they've never properly assessed their risk, or they're overpaying for policies they don't need because a broker sold them a bundle and they never questioned it.
Neither position is ideal. Being underinsured means a single event, whether that's a client lawsuit, a workplace injury, or a fire, can financially destroy a business that took years to build. Being overinsured means you're paying thousands a year in premiums for coverage that doesn't match your actual risk profile.
This guide cuts through the noise and covers the specific insurance policies that Australian SMEs need, which ones are legally required, what they typically cost, and how to avoid paying for coverage you'll never use.
If you have employees (including some contractor arrangements), workers' compensation insurance is mandatory in every Australian state and territory. There are no exceptions. If an employee is injured at work and you don't have workers' comp, you're personally liable for their medical costs, lost wages, and any lump sum compensation, plus you'll face significant fines.
Workers' comp is administered by different bodies in each state. In NSW it's icare, in Victoria it's WorkSafe, in Queensland it's WorkCover Queensland, and so on. Premiums are calculated based on your industry classification, your wage bill, and your claims history. A low-risk office-based business might pay 1% to 2% of wages. A high-risk construction or manufacturing business could pay 5% to 10% or more.
Most states require you to have a policy in place before your first employee's start date. Don't leave this to the last minute.
If your business owns or leases vehicles, Compulsory Third Party (CTP) insurance is included in your vehicle registration. This covers injury to other people in an accident. It doesn't cover damage to your vehicle, damage to other vehicles, or damage to property, which is why many businesses also carry comprehensive motor vehicle insurance or third-party property damage insurance.
Public liability covers you if a member of the public is injured or their property is damaged as a result of your business activities. If a client visits your office and trips on a loose cable, if a delivery you arrange damages a customer's property, or if someone is injured at an event you're running, public liability responds.
Most commercial leases require tenants to hold public liability insurance, typically with a minimum cover of $10 million to $20 million. Many clients (particularly government and enterprise clients) require it before they'll sign a contract with you.
Cost: $400 to $2,000 per year for most low-risk SMEs. Higher for businesses with significant foot traffic or physical risk.
Professional indemnity (PI) covers you if a client claims they've suffered a financial loss due to your professional advice or services. If you're an accountant, consultant, architect, engineer, IT provider, financial planner, or any other professional services business, PI insurance is essential. Some industries require it by law (financial services, legal, medical). Others don't legally require it but would be taking an unacceptable risk operating without it.
PI insurance covers legal defence costs, settlements or judgments, and the cost of rectifying the work that caused the problem.
Cost: $1,000 to $5,000 per year for most professional services businesses. Higher for industries with greater exposure (financial advice, engineering, medical).
Business interruption insurance covers lost income and ongoing expenses if an insured event (fire, flood, storm, equipment breakdown) forces you to stop trading. It's designed to put your business in the same financial position it would have been in had the event not occurred.
This is the policy that most businesses don't think about until they need it. A fire that destroys your premises doesn't just cost you the physical assets. It costs you weeks or months of revenue while you find new premises, replace equipment, and rebuild operations. Business interruption insurance covers the revenue gap.
Cost: varies significantly based on your revenue, industry, and the events covered. Budget $1,000 to $5,000 per year for most SMEs.

If your business stores customer data, processes payments, or relies on digital systems (which is essentially every business in 2026), cyber liability insurance is increasingly important. It covers the costs associated with a data breach, including notification costs, credit monitoring for affected customers, legal fees, regulatory fines, and business interruption caused by a cyber attack.
The Australian government's mandatory data breach notification scheme means that any business covered by the Privacy Act must notify affected individuals and the OAIC if a data breach is likely to result in serious harm. The costs of managing a breach, even a small one, can run into tens of thousands.
Cost: $500 to $3,000 per year for most SMEs. Higher for businesses handling sensitive financial or health data.
Only relevant if your business manufactures, imports, distributes, or sells physical products. If you're a services-only business, you don't need this. If you do sell products, it's bundled with public liability in most policies.
Primarily relevant for businesses with boards, external investors, or complex governance structures. For a standard owner-operated SME, this is often unnecessary. However, if you have external directors, are raising capital, or operate in a regulated industry, it's worth considering.
Relevant if your business is highly dependent on one or two people (usually the founder). It pays a lump sum if that person dies or becomes permanently disabled. For a solo founder with no employees, this is essentially life insurance for the business. Worth considering, but not essential for all SMEs.
Step 1: Identify your actual risks. Don't start with a broker's recommendation. Start with a list of the things that could realistically go wrong in your business. Client lawsuits, employee injuries, property damage, data breaches, and business interruption are the big ones for most SMEs.
Step 2: Get multiple quotes. Don't just go with the first broker. Use comparison platforms like BizCover, iSelect Business, or Simply Business to get quotes from multiple insurers. This takes 15 minutes and can save you thousands.
Step 3: Review annually. Your insurance needs change as your business grows. A business that had 5 employees two years ago and now has 20 needs a very different level of coverage. Review your policies at each renewal, not just the premium, but the coverage limits, exclusions, and excess amounts.
Step 4: Increase your excess to lower premiums. If you can comfortably absorb the first $1,000 to $2,000 of a claim, opting for a higher excess can significantly reduce your annual premium. Just make sure you can actually afford the excess if you need to claim.
Step 5: Bundle where it makes sense. Most insurers offer Business Insurance Packs (BIPs) that combine public liability, professional indemnity, business interruption, and other policies into a single package at a lower total premium than buying each separately. Check what's included and what's excluded before committing.

For a low-risk professional services business with 5 to 15 employees, a typical annual insurance spend looks like this: public liability ($10M to $20M cover) at $500 to $1,500, professional indemnity ($1M to $5M cover) at $1,500 to $4,000, workers' compensation at 1.5% to 3% of wages, cyber liability at $500 to $2,000, and business interruption at $1,000 to $3,000.
Total: roughly $5,000 to $15,000 per year for a comprehensive insurance program. This scales with your revenue, headcount, and industry risk profile.
For higher-risk industries (construction, manufacturing, healthcare), expect significantly higher premiums, particularly for workers' compensation and public liability.
Keep in mind that business insurance premiums are tax-deductible expenses, which reduces the after-tax cost by your marginal tax rate (25% for base-rate companies, higher for non-corporate structures).
Is business insurance tax-deductible in Australia?
Yes. Business insurance premiums are generally fully deductible as a business expense in the year they're incurred. This applies to all standard business policies including public liability, professional indemnity, workers' compensation, and business interruption insurance.
Do sole traders need business insurance?
Sole traders don't have the same legal requirements as companies (no workers' comp needed if you have no employees), but public liability and professional indemnity are still strongly recommended if you're providing services to clients. A single claim without insurance could wipe out your personal assets since sole traders have unlimited personal liability.
What's the difference between public liability and professional indemnity?
Public liability covers physical injury and property damage. Professional indemnity covers financial loss caused by your professional advice or services. A client who slips in your office is a public liability claim. A client who loses money because of your incorrect advice is a professional indemnity claim. Most professional services businesses need both.
How often should I review my business insurance?
At minimum, annually at renewal time. You should also review whenever there's a significant change in your business: new employees, new services, new locations, a major contract, or a significant increase in revenue. Any of these can change your risk profile and coverage needs.
Can I cancel business insurance mid-policy?
Most policies allow cancellation with a pro-rata refund of unused premium. Check your policy's specific terms. Workers' compensation typically can't be cancelled while you have employees.
What happens if I'm underinsured when I make a claim?
If your sum insured is less than the actual loss, many policies include an averaging clause that reduces your payout proportionally. For example, if you're insured for $500,000 but the actual value at risk is $1,000,000, you might only receive 50% of your claim. This is why getting coverage amounts right matters.
