NCC 2025 Is Here
The Australian Building Codes Board (ABCB) has released NCC 2025, introducing the latest edition of the National Construction Code.
While the new Code commenced on 1 May 2026 in most Australian jurisdictions, adoption is not consistent across the country. Each state and territory determines when NCC 2025 takes effect through its own legislation.
Where does NCC 2025 apply?
Commenced 1 May 2026
- Victoria
- Tasmania
- Northern Territory
- Australian Capital Territory (transition periods for certain project)
- Western Australia (transition periods for certain projects)
Commencing 1 May 2027
- New South Wales
- Queensland
- South Australia (building provisions)
For organisations delivering projects nationally, confirming which NCC edition applies is now more important than ever.
What's changed?
Unlike NCC 2022, which introduced significant regulatory reform, NCC 2025 is a targeted update focused on refining existing provisions.
Key changes include:
- Strengthened water management provisions
- New fire safety requirements for enclosed carparks
- Further refinement of condensation and moisture management
- Updates to commercial energy efficiency provisions
- Improved clarity and consistency throughout the Code
What does this mean for your project?
The release of NCC 2025 does not automatically make it mandatory across Australia.
Project teams should confirm the applicable Code edition before commencing design or lodging for approval, particularly where projects span transition periods or operate across multiple states.
For Victorian projects, Section 10 of the Building Act 1993 may continue to provide transitional arrangements where substantial design work commenced prior to the introduction of NCC 2025.
