Professional indemnity covers a client’s financial loss caused by your advice, design or professional service. Public liability covers injury to people and damage to their property caused by your business activities. The professional indemnity vs public liability question comes down to what went wrong: a mistake in the work that costs someone money, or physical harm. Many consultants, tradies and small firms need both, because one job can produce either kind of claim and client contracts often ask for the two side by side.
The kind of loss decides which policy responds
Start with what went wrong, not with your occupation. business.gov.au describes professional indemnity insurance as cover for the cost of legal action over claims against your professional advice or services, including mistakes, neglect or breaches of contract that cause a loss for your client. It describes public liability insurance as cover for when someone dies, is injured or has their property damaged because of your negligence.
So a client who paid too much, missed a deadline or lost a sale because of your work points to professional indemnity. A person who tripped over your equipment, or a client whose floor you damaged, points to public liability. Public liability can still pay a financial loss, but only one that follows physical harm: business.gov.au lists consequential loss, where negligence causes another business to lose expected revenue, among the things it may cover. A fire you start in a shared building that closes the shop next door is one example.
| What happened | Policy that usually responds |
|---|---|
| A bookkeeper lodges a client’s return late and the client is charged penalties | Professional indemnity |
| A visitor trips on a cable in your office and breaks a wrist | Public liability |
| An interior designer specifies a floor finish that fails and has to be replaced | Professional indemnity |
| A painter knocks over a tin and ruins a client’s carpet | Public liability |
| A consultant’s cost estimate is wrong and the client’s project runs over budget | Professional indemnity |
| An engineer’s design error leads to a structure failing and injuring someone | Possibly both, so read both wordings |
Professional liability and professional indemnity are the same cover
Contracts and insurer websites use both names, which is where the confusion starts. In Australia the policy is usually sold as professional indemnity. Professional liability is the name some insurers use, and the one common in contracts drafted overseas. Both describe cover for claims that your professional work caused a client a financial loss. When a contract asks for professional liability, a professional indemnity policy at the stated limit normally answers it. Check the definition in the contract if you are unsure, and ask the client in writing rather than guessing.
Where tradies and consultants fall between the two
The gaps sit at the edges of each policy. Public liability wordings commonly exclude claims arising from professional advice or design given for a fee. Professional indemnity wordings commonly exclude bodily injury and property damage, although some policies written for engineers, architects and other design professions include it where the harm flows from a breach of professional duty.
That matters for anyone who both advises and does the work. A tradie who designs a system and then installs it, a builder who prepares the drawings on a design and construct job, or an IT contractor who recommends a setup and then configures it on site can face either kind of claim from the same job. The installation and the site visit belong to public liability. The design and the recommendation belong to professional indemnity.
Neither policy is designed to pay for redoing your own work. Public liability commonly excludes damage to the work you performed, and professional indemnity pays the client’s loss, not the cost of fixing a job you simply did badly. Treat that as a business risk, priced into your quotes.
Why the two policies behave differently
Public liability is commonly written on an occurrence basis. The policy in force when the incident happened responds, even if the claim arrives years later. Professional indemnity is written on a claims made basis, so the policy in force when the claim is made responds, which is why a professional indemnity policy has to stay current after a job finishes. Our article on management liability vs professional indemnity explains claims made cover and retroactive dates in more detail.
The limits look very different too. Public liability limits of 10 million or 20 million dollars are commonly requested, while professional indemnity is commonly requested at 1, 2 or 5 million dollars. Neither figure is set by law for most businesses. They come from contracts, permits and professional bodies, and business.gov.au notes that professional indemnity is mandatory for some professions.
What a contract or permit will spell out
When a client sends an insurance clause, the professional indemnity vs public liability question is usually answered for you. Read the clause for:
- The class of each policy it names, such as public and products liability, professional indemnity, or general liability.
- The minimum limit for each, and whether it applies per claim or in the aggregate.
- How long cover must stay in place after the work ends, which is common for professional indemnity.
- Whether the client must be noted on the policy as an interested party.
- When a certificate of currency is due, and at which renewals.
Councils draw the same line. The City of Melbourne’s public liability guidance asks permit holders for public and products liability, or general liability, of at least 20 million dollars for a single claim, and says professional indemnity may be required for certain permits, such as planning or advice based permits. The activity decides the class.
What FRS does
We read your contracts and permits, list which classes and limits each one demands, and check the business description on both policies against the work you actually do, including any design or advice you give alongside a trade. Where a job carries both kinds of risk, we place both covers and make sure the gaps between the two wordings are known before you sign. Both often sit inside a wider business insurance program.

Frequently asked questions
Do I need both professional indemnity and public liability?
Often, yes. If you give advice or design and you also visit sites or work on client premises, one job can produce a claim for financial loss and a claim for injury or damage. Each policy commonly excludes the other’s risk. A consultant who never leaves the office may need little public liability, but most contracts still ask for it.
Is professional liability insurance the same as professional indemnity?
Yes, in practice. Professional indemnity is the usual Australian name, while professional liability is used by some insurers and in contracts drafted overseas. Both cover claims that your professional work caused a client a financial loss. If a contract asks for professional liability, a professional indemnity policy at the stated limit normally satisfies it. Confirm with the client in writing.
Does public liability cover a mistake in my advice?
Generally not. Public liability commonly excludes claims arising from professional advice or design given for a fee, because that risk belongs to professional indemnity. It responds when your activities injure someone or damage their property. If the only loss is money, such as a client overpaying or missing a deadline, the claim points to professional indemnity.
Why are public liability limits so much higher than PI limits?
Because the worst cases differ. A single fire or serious injury can produce a very large claim, so contracts and councils commonly ask for 10 or 20 million dollars of public liability. Professional indemnity claims are usually financial and are commonly requested at 1, 2 or 5 million dollars. Your contract sets the figure, not a law.
