Country: Australia
Architectural code and regulatory reference for projects in any Australian state or territory. Activate this skill on any Australian city/state reference (Sydney, Melbourne, Brisbane, Perth, Adelaide, Canberra, Hobart, Darwin), AUD currency, mention of "NCC"/"BCA"/"AS"/"AS/NZS"/"NatHERS"/"BASIX"/"Premises Standards", Green Star, or state acronyms (NSW, VIC, QLD, WA, SA, TAS, ACT, NT).
1. Regulatory Hierarchy
Australia operates as Archetype B (National Model + State Adoption) with Archetype E (Performance-Based) characteristics. The NCC is a single performance-based code adopted by each state's Building Act, with state-specific variations published as A1-A8 appendices.
1.1 Authority Stack
LEVEL 1 -- NATIONAL
Australian Building Codes Board (ABCB) -- publishes NCC; Federal-State joint
Standards Australia -- publishes AS / AS/NZS standards
Commonwealth Government:
- Disability Discrimination Act 1992 (DDA) -- enforced by Australian Human Rights Commission
- Disability (Access to Premises -- Buildings) Standards 2010 -- mirrors NCC
- National Construction Code Strategy
Australian Bureau of Statistics + IBM -- climate + earthquake data
Geoscience Australia -- seismic + flood
Bureau of Meteorology -- climate data
LEVEL 2 -- STATE / TERRITORY
Each of 8 jurisdictions has:
Building Act / Building Regulations
Building Authority (regulator)
Building Surveyors Registration body
Planning system (separate from building)
NSW: Department of Customer Service (Building Commissioner); Department of Planning
VIC: Victorian Building Authority (VBA); Department of Transport and Planning
QLD: Queensland Building and Construction Commission (QBCC); Department of Energy + Public Works
WA: Building Commissioner (Department of Mines + Industry Regulation + Safety -- DMIRS); Department of Planning, Lands + Heritage
SA: Office of the Building Authority (now Construction Industry Training Board oversight); Plan SA
TAS: Department of Justice -- Consumer, Building + Occupational Services
ACT: Access Canberra (Environment, Planning + Sustainable Development)
NT: Department of Infrastructure, Planning + Logistics
LEVEL 3 -- LOCAL
Local Council (Council, Shire, Borough) -- often planning authority
+ Building Surveyor (private competition)
+ Council Planning Officer
Fire + Rescue (state agency) -- consultation for performance solutions
Environment Protection Authority (state) -- pollution
LEVEL 4 -- PROJECT
Registered Building Surveyor -- assesses NCC compliance + issues Building Permit
Registered Building Practitioner -- Architects (Architects Act + Board of Architects each state),
Engineers (often via Engineers Australia chartered status)
Fire Engineer (FPA Australia accredited) for Performance Solutions
Access Consultant (AAAA accredited) for accessibility advice
NatHERS Accredited Assessor for energy ratings (housing)
Section J / Part J6 assessor for energy (commercial)
1.2 Adoption Across States
The NCC 2022 is adopted in each state via Building Act:
- NSW: Environmental Planning + Assessment Act 1979 + Environmental Planning + Assessment Regulation 2021
- VIC: Building Act 1993 + Building Regulations 2018
- QLD: Building Act 1975 + Building Regulation 2021
- WA: Building Act 2011 + Building Regulations 2012
- SA: Planning, Development + Infrastructure Act 2016 + Planning, Development + Infrastructure (General) Regulations 2017
- TAS: Building Act 2016 + Building Regulations 2016
- ACT: Building Act 2004 + Building (General) Regulation 2008

Each state publishes its State Variations as part of the NCC (Appendix to relevant volumes). E.g., NSW has bushfire + flood overlays; QLD has cyclone + termite; WA has cyclone north; NT has tropical cyclones.
2. NCC 2022 Structure
The National Construction Code 2022 (current as of writing; periodic updates) comprises three Volumes:
