Business insurance in Australia is not one policy – it is a set of different covers, and which ones you actually need depends heavily on your industry, whether you have staff, and what kind of risk your business carries. Only one type is universally required by law. Everything else is a genuine risk decision, not a checkbox. Here is what each cover actually does, roughly what it costs, and how to work out what your business needs.
Key Takeaways
- Workers compensation is the only business insurance legally required in Australia, and only if you have employees.
- Public liability, professional indemnity and cyber liability are not legally mandatory for most businesses, but are often required by clients, landlords, or licensing bodies.
- A single injury claim, fire, or data breach can run into five or six figures – the financial risk of going uninsured is often far larger than the premium.
- Business interruption costs make up nearly 80% of cyber insurance claims, not just the direct cost of the breach itself.
- Combining multiple covers with one insurer can reduce premiums and simplify renewals compared with several standalone policies.
The Main Types of Business Insurance
- Public liability insurance. Covers physical injury or property damage you cause to a member of the public – for example, a customer slipping in your store. Often required by landlords, clients, or as a condition of a trade licence. Typical cover for $20 million sits roughly $500–$900 a year.
- Professional indemnity insurance. Covers financial loss a client suffers due to negligent advice or errors in your professional service. Mandatory for certain professions including health practitioners, lawyers, accountants and mortgage brokers, and commonly required by clients even where it is not compulsory. Roughly $800–$2,500 a year for $1–5 million in cover, heavily dependent on industry.
- Cyber liability insurance. Covers the costs of responding to a data breach or cyber attack – IT forensics, legal fees, regulatory notification costs, and lost income while systems are down. Worth serious consideration if you store customer data or process online payments. Roughly $1,000–$2,500 a year.
- Management liability insurance. Protects the business and its directors or managers against claims arising from decisions made running the company – hiring and firing disputes, financial errors, and similar exposures. Roughly $1,200–$3,000 a year.
- Business interruption insurance. Covers lost income or profit when your business is disrupted by an insured event, such as a fire or major equipment failure.
- Workers compensation insurance. The only business insurance legally required in Australia if you employ staff. It covers lost wages and medical costs when an employee is injured or becomes unwell because of their work. Requirements and providers vary by state and territory.
What Is Actually Required by Law
Workers compensation is the sole legal requirement, and only once you have employees. Everything else – public liability, professional indemnity, cyber, management liability – is not universally mandated, but can be a practical requirement in a different sense: many client contracts, commercial leases, and industry licences specify a minimum level of cover before you can operate, even though the law itself does not.
How to Work Out What You Need
- Check your contracts and lease first. Before assuming what you need, review major client contracts, your commercial lease, and any licensing requirements – these often specify minimum cover you must already carry.
- Match cover to your actual risk. A business that gives professional advice needs professional indemnity more than a retail store does; a business handling customer payment data needs cyber cover more than one that does not.
- Home-based businesses still need cover. Most home and contents insurance does not cover business-related claims, such as equipment theft or a client injured on your property, so a standalone public liability policy is often necessary even if you work from home.
- Review annually. Hiring staff, adding a location, or expanding your services all change your risk profile and should trigger a policy review, not just your renewal date.
Ways to Manage the Cost
- Combining public liability, professional indemnity, property or cyber cover with a single insurer can reduce premiums and simplify renewals compared with separate standalone policies.
- A slightly higher excess can lower your premium, provided the excess amount is genuinely affordable if you need to claim.
- Insurers often reward risk-reduction measures – documented safety procedures, cybersecurity protocols, staff training, and secure storage can all bring premiums down over time.
Frequently Asked Questions
Do sole traders need business insurance?
It depends on the work. A sole trader providing professional advice, working on client property, or handling customer data carries the same underlying risks as a larger business and often needs the same core covers, even without employees.
Is cyber insurance worth it for a small business?
If you store customer data or process online payments, it is worth serious consideration – data breach costs frequently exceed $50,000. And business interruption alone makes up around 80% of cyber insurance claims, not just the direct breach response.
Does business insurance cover my work vehicle?
No. Business insurance packages generally do not include vehicle cover, so commercial vehicles need to be insured separately.
What happens if I operate without required insurance?
Beyond the direct financial risk of an uninsured claim, operating without insurance required by a licence, contract, or lease can breach those agreements entirely, which carries its own separate consequences beyond the original incident.
