How Much Professional Indemnity Insurance Do I Need in Australia?
There is no single Professional Indemnity Insurance limit that suits every Australian professional or business. The right level of PI cover depends on the services you provide, the size of your projects, your contractual obligations, the potential financial loss a client could suffer and any regulatory or professional requirements that apply to you.
A $1 million limit may be appropriate for one low-risk consultant but inadequate for another business with larger contracts, high-value clients, complex advice or long-tail exposure. The goal is not simply to meet a minimum requirement—it is to ensure your business has a realistic level of protection if a claim arises.
What is a Professional Indemnity Insurance limit?
Your PI Insurance limit of indemnity is the maximum amount an insurer may pay for a covered claim, subject to the policy wording.
Professional Indemnity limits are often quoted as:
$1 million
$2 million
$5 million
$10 million
$20 million or more
However, the stated limit is only part of the picture. You should also establish whether it applies per claim, in the aggregate across all claims in a policy period, and whether legal defence costs are included within or payable in addition to that limit.
How do I choose the right PI Insurance limit?
When deciding how much Professional Indemnity Insurance you need, assess your genuine exposure rather than selecting the lowest-cost option.
1. Your profession and services
Different services create different risks. A consultant providing high-level strategic advice, an engineer working on major projects, a mortgage broker assisting clients with finance, or an IT provider implementing critical systems may all face different potential claim values.
Your PI policy must reflect the professional services you actually provide. If your activities have changed, expanded or become more complex, your limit and wording should be reviewed.
2. Your largest project or client engagement
Consider the value and consequences of your largest engagement—not only your annual turnover.
Ask:
What is the largest financial loss a client could allege from our work?
Could one error affect an entire project, transaction or business operation?
Would a client’s lost revenue, rectification costs or third-party claims exceed our current PI limit?
Are we working with large corporates, government bodies, developers or regulated clients?
A small professional fee can still create a large liability exposure if a client relies heavily on the advice or service.
3. Contractual insurance requirements
Many client contracts, tenders, leases and professional appointments set minimum PI Insurance limits. A contract may require $2 million, $5 million, $10 million or another prescribed limit.
But a contractual minimum is not automatically the right amount for your business. Review the indemnity clauses, scope of liability, contract value and professional obligations. You should avoid agreeing to contractual liability you cannot insure.
4. Legal defence costs
A claim does not need to succeed to become expensive. Legal fees, expert reports, investigations and court processes can use a significant portion of the policy limit.
Check whether your PI Insurance is:
Costs inclusive: legal defence costs reduce the stated limit; or
Costs exclusive: covered defence costs may be payable in addition to the stated limit.
This distinction can materially change the amount available to resolve a claim. The Tax Practitioners Board specifically notes that registered tax practitioners require legal and defence costs in addition to the amount of cover, and that a practitioner may need more than the applicable minimum. TPB guidance
5. Regulatory, licence and professional-body requirements
Some professionals must meet minimum PI Insurance requirements. These can vary according to the profession, jurisdiction, licence, registration and services provided.
For example, ASIC assesses whether credit licence applicants have adequate PI insurance where required. ASIC guidance
Always confirm the current rules that apply to your own profession. Minimum compliance is a starting point, not necessarily a complete risk assessment.
6. Your past work and retroactive date
PI Insurance is commonly claims-made cover. A claim may relate to advice or services delivered years ago. Your retroactive date determines how far back your current policy may cover work, while the limit must be adequate for both current and historical exposures.
This is especially important if you have changed insurers, changed business entities, expanded your services or taken on larger projects.
Is $1 million PI Insurance enough?
It may be sufficient for some lower-risk professionals, sole traders or businesses with modest client exposure. It may be inadequate for businesses with higher-value contracts, complex professional services, larger clients or substantial potential loss.
There is no responsible universal answer. A limit should be assessed against your actual work, not chosen because it is a commonly available option.
Do sole traders need Professional Indemnity Insurance?
Sole traders can face the same allegation risks as larger firms. If clients rely on your advice, expertise, services, designs, reports or recommendations, a Professional Indemnity claim can still arise.
The appropriate limit for a sole trader depends on the work they perform, client type, contracts, turnover, prior work and potential financial consequences—not simply the number of employees.
Questions to ask before arranging or renewing PI Insurance
Before choosing a limit, ask:
What professional services do we provide?
What is our largest current or planned project?
What limit do our contracts require?
Are defence costs included in the limit?
Does the policy cover our past work from the correct retroactive date?
Are subcontractors, employees and prior entities properly addressed?
Could one error affect multiple clients or a larger transaction?
Has our turnover, project size or service offering changed since last renewal?

Choosing a PI limit is a business-risk decision, not a box-ticking exercise. The right cover should align with the services you provide, the clients you serve, your contractual commitments and the financial consequences of a potential claim.
