Business liability insurance options compared
| Option | How it works | Good for | Watch out for |
|---|---|---|---|
| Public liability (often sold as broadform public and products liability) | Pays compensation and legal costs if your business activities injure someone or damage their property; usually written on an occurrence basis | Tradies, retailers, cafes, event operators and any business with customers, sites or premises | Exclusions for professional advice, faulty workmanship, property in your care and contractual liability; the excess often applies to property damage claims |
| Products liability | Covers injury or property damage caused by goods you make, sell, supply or import; usually limited in the aggregate for the policy period | Manufacturers, importers, online sellers and wholesalers | Importers can be treated as the manufacturer under the Australian Consumer Law; exports to the USA or Canada are often excluded or loaded |
| Professional indemnity | Covers claims that your advice, design or professional service caused financial loss; written on a claims-made basis | Consultants, accountants, IT contractors, engineers, architects and advisers | Retroactive date, notification of circumstances and run-off cover after you stop trading |
| Management liability | Packages directors' and officers' liability, employment practices, statutory liability and sometimes crime cover for private companies | Companies with employees, directors and outside investors | Penalties that cannot legally be insured, including WHS fines in jurisdictions that prohibit it |
Frequently asked questions
How do I compare public liability insurance quotes in Australia?
Ask each insurer or broker to quote the same activities, turnover, limit and territory, then compare the total payable including GST, stamp duty and fees. Check the excess for property damage, whether products liability is included, and the main exclusions. The worked comparison shows the arithmetic.
Is public liability insurance compulsory?
There is no general law that requires every business to hold public liability insurance. In practice it is often required by leases, councils, venues, head contractors, licensing bodies and industry associations, commonly at $10 million or $20 million. Workers compensation is compulsory for employers, and some professions must hold professional indemnity insurance.
Why are GST and stamp duty added to my business insurance premium?
GST of 10% applies to general insurance premiums, and each state and the Northern Territory charges insurance duty on top, generally calculated on the premium including GST. The ACT abolished insurance duty. A GST-registered business can usually claim the GST as an input tax credit but not the duty. See the GST and stamp duty guide.
What is the difference between public liability and professional indemnity?
Public liability covers injury to people and damage to their property caused by your business activities. Professional indemnity covers financial loss caused by your advice or professional services, usually on a claims-made basis. Many businesses need both. See public liability versus professional indemnity.
Do I have to tell my insurer everything when I take out business cover?
Yes. Business policies are generally not consumer insurance contracts, so the duty of disclosure in section 21 of the Insurance Contracts Act 1984 applies when you take out, renew, vary or reinstate cover. You must disclose matters you know, or a reasonable person in your circumstances would know, are relevant to the insurer's decision.
Can I pay business insurance monthly?
Usually yes, through premium funding arranged by a broker or insurer, or through an insurer's own instalment option. Funding is a separate credit contract with interest and fees, and missed payments can lead to the policy being cancelled. The premium funding calculator estimates the extra cost.
What can I do if my business insurance claim is declined?
Ask for the reasons in writing and make a complaint through the insurer's internal dispute resolution process, which generally must give a final response within 30 calendar days. If you are not satisfied and your business is a small business, you can usually take the complaint to AFCA free of charge. See the AFCA guide.
