Professional Indemnity Insurance in Australia: What It Covers, Who Needs It and How to Choose the Right Cover
Professional advice comes with professional responsibility. Whether you are an accountant, consultant, engineer, architect, mortgage broker, real estate professional, IT provider or designer, a client can allege that your advice, service or failure to act caused them financial loss.
Professional Indemnity Insurance, commonly called PI insurance, is designed to help protect Australian professionals and businesses from the financial consequences of those allegations. It can be important even where you believe you have acted appropriately: defending an allegation can still involve significant legal and professional costs.

What is Professional Indemnity Insurance?
Professional Indemnity Insurance is business insurance intended to respond to civil liability claims connected with your professional services. Depending on the policy wording, it may help with legal defence costs and compensation or damages arising from allegations of:
Professional negligence
Errors or omissions
Breach of professional duty
Incorrect, incomplete or misleading advice
Breach of confidentiality
Defamation
Loss of client documents or data
Certain unintentional intellectual-property infringements
Cover, limits, exclusions and conditions differ between policies. The crucial question is whether the policy accurately reflects the services your business actually provides—not merely the job title on your application.
Who needs PI insurance in Australia?
PI insurance can be valuable for any person or business whose clients rely on their expertise, advice, designs, reports, recommendations or professional services. It is commonly arranged by:
Accountants, bookkeepers and tax professionals
Mortgage brokers and finance professionals
Architects, building designers and engineers
IT consultants, software developers and digital agencies
Real estate agents, property managers and strata professionals
Management, HR and business consultants
Marketing, recruitment and design professionals
Surveyors, quantity surveyors and project consultants
For some professions, PI insurance may be required by a regulator, professional body, employer or client contract. For example, ASIC assesses whether credit licence applicants hold adequate PI insurance where it is required, while tax practitioners must maintain cover that includes retroactive protection. Requirements can depend on your profession, licence, location, registration status and services, so they should be checked for your own circumstances. ASIC guidance, Tax Practitioners Board guidance
What does PI insurance not cover?
PI insurance is not a substitute for every form of business cover. Deliberate wrongdoing, known circumstances, contractual liabilities you have voluntarily assumed, bodily injury, property damage, cyber events or employment disputes may be excluded or require separate insurance. Exact treatment depends on the policy.
Public Liability Insurance and Professional Indemnity Insurance also address different risks. Public Liability generally responds to third-party injury or property damage; PI is directed at financial loss alleged to have arisen from professional advice or services. Many professional businesses need both.
Is PI insurance claims-made cover?
Most PI policies are written on a “claims-made” basis. In plain English, the policy in force when a claim is first made and notified is usually the policy that may respond—subject to its terms and the relevant work falling after the policy’s retroactive date.
That makes continuous cover extremely important. Allowing a PI policy to lapse can create a gap that affects protection for past work, even when the work was performed years earlier.
What is a retroactive date?
Your retroactive date is generally the earliest date from which past professional work may be covered under the policy. Work completed before that date may fall outside cover, even if the claim is made during the current policy period.
When changing insurers or renewing, professionals should carefully check that their retroactive date is retained. This is especially important after a business restructure, merger, change of entity, expansion of services or a gap in insurance.
Do I need run-off cover when I retire, sell or close my business?
Potentially, yes. A client may raise a claim after you stop trading, sell the business or retire. Run-off cover can help protect against claims made after the business ceases that relate to earlier professional services. The suitable duration depends on your profession, contractual obligations, limitation periods and the nature of your past work.
How much does Professional Indemnity Insurance cost?
There is no single PI insurance price in Australia. Premiums and available limits are influenced by:
Your profession and actual services
Annual revenue and fee income
Business size and claims history
Client type, contract values and project complexity
Required limit of indemnity
Excess amount
Retroactive date and continuity of cover
Overseas work, high-risk activities or contractual obligations
The cheapest policy is not necessarily the most appropriate one. A lower premium can be less valuable if the wording excludes a key service, the limit is inadequate or the retroactive date leaves past work exposed.
How much PI cover do I need?
The right limit should be assessed against your real exposure, not chosen solely because it meets a minimum contractual requirement. Consider your largest engagement, the potential financial loss if your advice is relied upon incorrectly, your contractual indemnities, the number of clients who could be affected by one issue and whether legal defence costs sit within or in addition to the limit.
A specialist review can also identify whether the policy needs extensions for areas such as subcontractors, former employees, document loss, defence costs, fidelity, cyber risks or run-off cover.
