Keeping our business partners up to date on market changes that matter
This update highlights the legal and regulatory developments, occurring in the first half of 2026, that we see as the most relevant within the Australian construction sector when it comes to professional indemnity insurance.
Legislative and Regulatory Developments
National Construction Code
The NCC undergoes updates every three years, with the publishing of NCC 2025 being delayed. However, NCC 2025 was introduced on 1 February 2026, with jurisdictions informed to adopt the amendments from 1 May 2026. The amendments to NCC 2025 include:
1. Amendments to car park fire safety to include requirements for sprinkler protection for open-deck car parks, and reduced scenarios where concessions to fire-resistance levels apply.
2. Introduction of measures aimed at reducing energy consumption in buildings, including mandatory on-site solar photovoltaic systems, and improved lighting control requirements.
Decennial Liability Insurance (NSW)
Plans to introduce Decennial Liability Insurance (DLI) into the NSW market are now in effect through amendments to the Strata Schemes Management Act 2015(NSW) to introduce definitions for defects covered under DLI.
Having passed in April of this year, DLI in strata schemes will become mandatory by 2028 and will essentially be a no-fault scheme. This will leave the door ajar for PI insurers to exercise subrogation rights to pursue at-fault parties within 24 months after a claim is made on a DLI policy.
There are further proposed amendments to the Fair Trading and Building Legislation Amendment Bill 2026 which would see DLI expanded into the construction industry more widely but these are not yet in effect.
Design and Building Practitioners Act 2020 (NSW)
Amendments effective 1 July 2026 include:
- Professional indemnity insurance for every registered building practitioner will be mandatory;
- DBPA also Expands to cover remedial work, specifically repairs and alterations on Class 3 and Class 9c buildings bringing a higher level of oversight and accountability to the maintenance and renovation on building types such as concrete repairs, waterproofing, structural strengthening or fire safety upgrades with requirement that they are carried out by registered building practitioners and lodged on the NSW Planning Portal.
Victoria Amendments
Surveyor and Inspector Registration Reform (VIC)
Some amendments to the Building Act 1993 (Vic) (the Act) have been passed and will come into force 1 September 2026. This essentially increases the training requirements for building surveyors before registration.
The primary amendment of relevance are the specific definitions in relation to “approved competence standard”, “approved prescribed qualification” and “prescribed competence criteria”. This sets out minimum competency standards in skills, experience and knowledge that must be met by applicants for registration as a building surveyor must meet. The introduction of these definitions lays the platform for building surveyors to be classed as registered building practitioners and subject to the requirements thereof as outlined in the Act.
As a result, the competency requirements of building surveyors have been increased. Tighter regulation of the industry, where insureds are compliant, may have the effect of reducing risk of insuring building surveyors and inspectors, assuming compliance by insureds.
Building and Construction Industry Security of Payment Act 2022 (VIC)
These amendments, coming into force on 1 September 2026, introduce changes to payment claims and corresponding damages claims include:
- Contractors will be able to include contested claims for scope variations, delay costs and latent conditions in payment claims
- Removal of reference dates permitting claimants to make one payment claim per month
- Definition of business day to exclude a black out period between 22 December to 10 January each year, suspending enforcement periods for claims
- Extending the last day for serving a payment claim to within six months of performance of the relevant construction work
- Due dates for progress claims to be 20 business days of issue of payment claims
- Restriction on pursuing only the defences and reasons set out in the payment schedule, not new reasons in adjudication
- Introduction of the power of adjudicators to declare contract terms as unfair and unenforceable.
Creation of the new Building and Plumbing Commission (VIC)
Amendments to the Building Legislation Amendment (Buyer Protections) Act 2025 will take effect from 1 July 2026 including the creation of the Building and Plumbing Commission which consolidates the Victorian Building Authority, the Domestic Building Dispute Resolution Victoria and the domestic building insurance of the Victoria Managed Insurance Authority.
The new Commission’s role will include regulatory monitoring, dispute resolution services, disciplinary functions and insurance oversight. The Commission will also have rectification powers allowing it to order the rectification of defective, incomplete or non-compliant building works.
With these new powers of the Commission, there may well be a corresponding reduction of legal costs if more claims are resolved at the Commission stage.
South Australia Amendments
The Statutes Amendment (Building and Construction Industry Review – Penalties) Act 2025 commenced on 15 January 2026 to strengthen consumer protections, introduce new offences, expand enforcement options and increase penalties in the building and construction industry.
The changes will affect the relevant legislation:
- Building work Contractors Act 1995;
- Fair Trading Act 1987;
- Magistrates Court Act 1991; and
- Plumbers, Gas Fitters and Electricians Act 1995.
These changes indicate a likely increase in regulatory action and inquiry in South Australia including:
- New offences related to unlicensed work
- Increased penalties for all offences including penalties up to $550,000
- Authorities have 2 years to prosecute most offences
International Model Building Act
In February 2026, the International Building Quality Centre introduced the International Model Building Act (IMBA) representing an international instrument for modern building regulation and is aimed at introducing clearer responsibility when defects arise, stronger oversight on construction and certification processes, and clearer resolution processes.
The IMBA is not in force in Australia and is not binding and is mainly designed to be read in conjunction with pre-existing regulations and legislature and currently adopts many features of current legislation, such as requirements of building certifiers. We will advise further if the IMBA is proposed to be adopted as binding in Australia.
Construction Case Law Developments
Interpretation of insurance contracts in a strict liability claim
Owners Corporation 1 Plan No. PS 650567Y v Shangri-La Construction Pty Ltd [2026] VSC 117
Construction contracts and limitation periods
Wang v Creation Homes Qld Pty Ltd [2026] FCA 136
Combustible cladding and contractual indemnities
The Star Entertainment Sydney Properties Pty Ltd v Buildcorp Group Pty Ltd t/as Buildcorp Interiors [2026] NSWSC 27
DBPA duties, “construction work” and proportionate liability
This case highlighted that claims that are poorly pleaded and lack of specific evidence to substantiate the alleged breach will be treated harshly by a court where the applicant attempts to impose a breach of the duty under section 37 of the DBPA.
Conclusion
Looking ahead to 2026 and beyond
