State-based insurance requirements.

Australia does not have one national registration and Professional Indemnity framework for engineers. Requirements depend on where the work is performed, the type of engineering service, whether the work relates to a regulated building and the role held by the practitioner.

The summary below is a starting point only. It distinguishes broad professional-engineer schemes from building, certification and accreditation requirements that apply to narrower classes of work.

Requirements at a glance

Queensland

Queensland operates a broad registration scheme under the Professional Engineers Act 2002. Professional engineering services generally must be carried out by a Registered Professional Engineer of Queensland (RPEQ), or under the direct supervision of one, unless an exemption applies.

The Board of Professional Engineers of Queensland Code of Practice requires RPEQs to take all reasonable steps to obtain and maintain Professional Indemnity insurance appropriate to the services they provide. The Board does not prescribe one minimum limit for every engineer. Cover should reflect the discipline, work profile and potential exposure, with limited exceptions including some employment arrangements and circumstances where insurance cannot reasonably be obtained.

New South Wales

New South Wales requires registration for professional engineering work on regulated class 2, class 3 and class 9c buildings. The prescribed engineering disciplines include civil, electrical, fire safety, geotechnical, mechanical and structural engineering.

Registered professional engineers must be adequately insured against liabilities arising from their work. The regime does not set one universal dollar limit: the practitioner must consider the nature and risks of the work, business structure and policy scope. Other engineers may still have insurance obligations under contracts, licences, professional standards schemes or employer requirements.

Victoria

Victoria requires registration in five prescribed areas: civil, structural, electrical, mechanical and fire safety engineering. Exemptions can apply where work is performed under the direct supervision of a registered engineer or only in accordance with a prescriptive standard.

An engineer who performs professional engineering services in the building industry must also hold the appropriate endorsement. Endorsed building engineers must maintain Professional Indemnity insurance that meets the Building Act 1993 and the current Ministerial Order. Because the prescribed terms and amounts can change, confirm the current requirements with the Building and Plumbing Commission before relying on an existing policy.

Western Australia

Western Australia’s scheme applies to prescribed categories of building engineering practitioner and building engineering contractor. The categories and transition timing depend on the engineering area and class of work.

A registered building engineering contractor must maintain appropriate Professional Indemnity insurance or meet the requirements of a qualifying Professional Standards Scheme. There is no single fixed minimum limit for every contractor; adequacy is assessed by reference to the work, risk, contractual obligations and business circumstances. Practitioners and contractors should check the current Building Services Board requirements for their category.

South Australia

As at this review, South Australia does not operate a general mandatory registration scheme for all professional engineers. The South Australian Government has consulted on possible reform, so the position should be monitored.

Separate requirements apply to accredited professionals under the planning system. Accredited professionals must hold adequate Professional Indemnity insurance, with minimum cover depending on the accreditation level. Building roles, contractual terms, employer policies and professional-body membership may create additional obligations.

Tasmania

Tasmania licenses building services providers, including relevant engineer classes, through Consumer, Building and Occupational Services. The licence class required depends on the services and building work undertaken.

Engineer applicants and licensees must provide evidence of current Professional Indemnity insurance. The published requirement is a minimum of $1 million, although contracts and project risk may justify a higher limit or broader cover.

Australian Capital Territory

The ACT Professional Engineers Registration Scheme commenced on 6 March 2025. Registration applies to professional engineering services in prescribed areas under the Professional Engineers Act 2023, subject to the legislation and any applicable exemptions.

Specific insurance is not required merely to apply for registration. However, the ACT Code of Practice requires registered engineers to take reasonable steps to maintain Professional Indemnity insurance appropriate to the services they provide. Engineers should also consider contractual, employer and project-specific insurance obligations.

Northern Territory

The Northern Territory registration framework is narrower than a general professional-engineer scheme. Certain certifying practitioners — including structural, hydraulic and mechanical engineers — are registered through the Building Practitioners Board under the territory’s building legislation.

Those registered certifying engineers must maintain continuous Professional Indemnity insurance. Current Board material specifies a minimum of $1 million. Other engineering work may still be subject to contractual, licensing, employer or professional-body requirements.

Practical steps for engineering practices

1. Check the regulator first: Confirm whether the individual, entity or both must be registered, licensed or endorsed for the work.
2. Match the policy to the role: A policy should reflect the disciplines, locations, services and project types actually undertaken.
3. Review contracts: Client agreements may impose higher limits, longer maintenance periods, specific policy terms or obligations extending beyond statutory minimums.
4. Confirm territory and jurisdiction: Make sure the policy responds where the work is performed and where a claim may be brought.
5. Plan for run-off: Registration and contractual obligations may continue to matter after work stops, a practice closes or a business is sold.
6. Keep evidence current: Regulators, clients and principals may require certificates of currency and other evidence at application, renewal or project milestones.
