Public liability insurance may help protect your small business against claims for injury or property damage caused to a third party (a customer, supplier, or member of the public) in the course of your business activities, subject to policy terms and conditions.

It is not legally mandatory for every Australian business but is practically required by most councils, landlords, venues, and commercial clients before you can operate, access a site, or win a contract. Here is what it covers, what it does not, and what it costs in 2026.

TL;DR

Public liability insurance may cover third-party injury and property damage claims.It does NOT cover your employees, your own property, professional advice errors, or faulty workmanship.$10 million is the most common cover level for Australian small businesses. $5M is often not enough.Average cost: around $39/month for low-risk businesses. Higher for trades and high-footfall industries.Premiums are tax deductible. The market has been softening since 2025.

What Public Liability Insurance May Include Cover For

Subject to policy terms and conditions, public liability insurance may include cover for:

• Legal defence costs and court-awarded compensation if a third party claims injury or property damage due to your business activities.
• Incidents at your own premises, at client sites, and at any other location where you are working.
• Products liability, where a product you sell, supply, or recommend causes harm to a third party. Most combined policies include this alongside public liability.
• Medical costs and other expenses associated with a successful claim, up to your policy limit.

What Public Liability Insurance Does NOT Cover

Understanding the exclusions is as important as understanding the coverage. Public liability insurance does not cover:

• Employee injuries. Workers compensation covers this. Public liability responds to third-party claims only.
• Your own property or equipment. Business pack or tools insurance covers your assets. Public liability addresses what you do to others.
• Professional advice errors. If your advice or recommendations cause a client financial loss, that is a professional indemnity claim, not a public liability claim.
• Faulty workmanship rectification. The cost of redoing your own defective work is typically excluded. Consequential damage caused to others may be covered.
• Intentional acts and criminal conduct. Deliberate damage or fraud is not insurable.
• Road vehicle incidents. These fall under your motor insurance, not public liability.

Public liability vs professional indemnity

A client slipping in your office is a public liability claim. A client losing money because of your advice is a professional indemnity claim. Many small businesses need both. If you provide professional services or advice, public liability alone does not address all your risk exposure.

$5 Million, $10 Million or $20 Million: Which Level Does Your Business Need?

Australian public liability policies are typically offered at three limits. The difference in annual premium between tiers is often surprisingly small, usually $100 to $300 per year, making the step up to higher cover relatively low cost for the additional protection.

$5 million. Suitable for low-risk, home-based operators with minimal public interaction and no contract requirements specifying a higher limit.

$10 million. The practical default for most Australian small businesses. It is the most common cover level purchased and is the minimum specified in many commercial contracts, council permits, and lease agreements.

$20 million. Required for commercial properties, shopping centre tenancies, larger construction sites, major events, and some council-managed spaces. Some state government tenders also specify this level.

Generally speaking, $10 million is the most common cover level held by Australian small businesses. It is the minimum specified in many commercial leases, council permits, and contractor agreements.

How Much Does Public Liability Insurance Cost in Australia?

Based on 2026 market data, most Australian small businesses pay between $400 and $1,500 per year for $5 to $10 million cover. The average across all business types is approximately $39 per month. Cost is driven by:

• Industry and occupation: higher-risk trades pay significantly more than office-based businesses.
• Annual turnover: more revenue typically means more exposure.
• Cover limit selected.
• Location: state stamp duty on premiums varies from 0% to 11% across Australian states and territories.
• Claims history: a clean record leads to better terms.

NSW small business stamp duty exemption

Businesses with annual turnover under $2 million in NSW pay zero stamp duty on public liability and selected other business insurance premiums. This is a material saving worth confirming with your insurer or broker when purchasing.

Public liability insurance premiums are fully tax deductible as a business operating expense. After several years of premium increases between 2019 and 2025, the market has been softening since mid-2025. Many small businesses are seeing flat or slightly reduced premiums at renewal for the first time in years.

Is Public Liability Insurance Legally Required for Small Businesses in Australia?

There is no single Australian law requiring every business to hold public liability insurance. However, it is practically mandatory in most situations because:

• Councils require it before issuing permits for outdoor events, markets, and commercial use of public spaces.
• Commercial landlords require a Certificate of Currency before a lease commences.
• Head contractors and principal contractors require it before subcontractors can access a site.
• Most commercial and government contracts specify minimum public liability limits as a condition of engagement.

Operating without it does not mean you are breaking the law. It means you cannot access most venues, win most commercial contracts, or operate in most public spaces. It also means you are personally exposed to the full cost of any successful claim.

For most other businesses, $10 million is the practical minimum and is the most common limit specified in commercial leases, council permits, and contractor agreements. Upgrading from $10 million to $20 million typically adds only $100 to $300 per year.

Is public liability insurance compulsory in Australia?

It is not legally mandatory for every Australian business. However, it is practically required by most councils, commercial landlords, head contractors, and government clients before you can operate, access a site, or win a contract. Operating without it means being personally exposed to the full cost of any third-party claim.

What does public liability insurance not cover?

Public liability does not cover employee injuries (workers compensation), damage to your own property (business pack insurance), professional advice errors (professional indemnity), faulty workmanship rectification costs, intentional acts, or road vehicle incidents. Understanding the exclusions is as important as knowing what is covered.

Does a sole trader need public liability insurance?

Sole traders are personally liable for any successful claim made against their business. Unlike a company structure, there is no corporate entity to absorb the cost. Most sole traders who interact with clients, work on client premises, or operate in public spaces hold public liability insurance for this reason. For a complete guide to insurance for sole traders, see our dedicated article.
