Public liability and professional indemnity insurance are often mentioned together, and many Australian businesses are asked about both. They answer different questions: one is about physical harm and property damage, the other is about advice and services. This guide sets them side by side, shows who tends to need each, and points to the rules for regulated professions.
Quick answer
Public liability responds to injury or property damage to third parties. Professional indemnity responds to claims about your advice or services that cause a client a loss. They are separate covers, and some businesses need both.

How the Two Covers Differ
The cleanest way to see the difference is to ask what went wrong. If a person was hurt or their property was damaged by what you did, that is a public liability question. Business Queensland gives a customer hurt by sharp machinery edges as an example. If a client lost money because of your advice or service, that is a professional indemnity question. business.gov.au describes it as covering mistakes, neglect or breaches of contract that cause a loss for your client.
Business Queensland adds that professional indemnity can pay defence costs, the third party's legal costs and court awards, up to the limit in the policy. Public liability policies often pay defence costs too, which our guide to what public liability covers explains. The key point: the same words, such as legal costs, appear in both, but the trigger is different, so a claim under one is not automatically a claim under the other.
Who Tends to Need Each Cover or Both
Picture a bookkeeper who visits clients' offices. A mistake in the books that costs a client money is a professional claim. A client's laptop knocked off a desk during a visit is property damage, which is a public liability claim. One person, two covers, and two sets of wording to read. The same split applies to anyone who advises, designs or inspects: the advice sits under professional indemnity, and the site visit sits under public liability.
That is why contracts often ask for both. A Queensland government page for building industry consultants requires a public liability policy with set terms and says the invitation documents state the professional indemnity amount. The page is dated: it was last updated on 7 July 2025 and last reviewed on 11 July 2024, so confirm the current figures with the licensing body. Business Victoria separately describes public liability as useful for any business that interacts face to face with customers, and professional indemnity as protecting professionals against negligence claims.
Rules for Regulated Professions
Some professions have rules about professional indemnity, and those come from regulators or professional bodies, not from this guide. We checked three sources.
| Source | What it says | Note |
|---|---|---|
| business.gov.au | Professional indemnity is mandatory for some professions, and associations may offer industry-specific cover at lower cost | Check with your association first |
| ASIC Regulatory Guide 126 | Australian financial services licensees must have compensation arrangements for retail clients, met by professional indemnity insurance or approved alternatives | The guide was published in November 2024 and does not mention public liability |
| Professional Standards Councils | A professional standards scheme is a legal framework approved by the councils, and schemes include professional indemnity insurance among their requirements | The page shows no date and does not say who must hold the insurance |
ASIC's guide also sets minimum limits by revenue. As we read Table 4, a licensee with retail revenue of $2 million or less needs a limit of at least $2 million. That applies to licensees, not to businesses generally, and the guide says licensees are primarily responsible for determining what is adequate for their own business. We do not interpret it further, so ask your adviser or your regulator.
Package or Separate Policies
Insurers sometimes combine covers. business.gov.au says packages tailored to a business type can be cheaper than separate policies. A package is only useful if its parts match your risks, though. Check that the professional indemnity section names your profession and that the public liability section has the limit your contracts want.
Our business guide explains packages, and our public indemnity guide explains why a contract's wording can blur the two covers.
How Pricing Works for Each Cover
We do not give a price for either cover. For public liability, the factors and the state duty rules are in our cost guide. For professional indemnity, we found no official source that lists rating factors, so we do not state any. The practical step is the same for both: give the broker or insurer a full description of your work, because under section 21 of the Insurance Contracts Act 1984 you must disclose what you know, or a reasonable person would know, is relevant. Our quotes guide explains the duty.
Questions to Ask Before You Buy
- Which of my contracts, licences or leases asks for each cover?
- Does the professional indemnity policy name my profession and services?
- Does either policy exclude the work I do?
- Are defence costs inside or in addition to the limit?
- If I buy a package, does each part have its own limit?
Where to Go Next on Cairn Cover
The one thing to remember: public liability and professional indemnity insurance cover different harms, so match each to the risk in your contract. Cairn Cover explains how cover works, links each source on the words it supports and does not sell insurance or give personal advice. Start with the national guide, then the business guide. Our Queensland guide shows how a licence can add its own insurance rule.
Frequently Asked Questions
Is professional indemnity insurance the same as public liability? No. Public liability responds to injury or property damage to third parties, while professional indemnity responds to claims about your advice or services. A claim under one is not automatically a claim under the other.
Do I need both public liability and professional indemnity insurance? It depends on your work and your contracts. Some businesses need both. Check what each contract, licence and lease requires, and ask a licensed adviser about your own risk.
Is professional indemnity compulsory? Not for every business, but mandatory for some professions. Your regulator or professional association sets the rule, so ask them for the current requirement.
Can one policy include both covers? Sometimes, as a package. business.gov.au says packages tailored to a business type can be cheaper than separate policies. Confirm that each part names your risks and has its own limit.
How much do the covers cost? We do not give prices. For public liability, our cost guide explains what moves the price. For professional indemnity, ask the broker or insurer what they need to know about your work.
How does Cairn Cover help? We explain the difference in plain English, link our sources on the words they support and connect related guides. We do not rank insurers, quote prices or give personal advice.
