The NCC 2022 is adopted in each state via Building Act:
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.
The National Construction Code 2022 (current as of writing; periodic updates) comprises three Volumes:
| Volume | Scope | Building Classes |
|---|---|---|
| Volume One -- Building Code of Australia (BCA) | Commercial, public, multi-residential buildings | Class 2 (apartments), Class 3 (hotels/dormitories), Class 4 (residential within a Class 5-9), Class 5 (offices), Class 6 (shops), Class 7 (storage), Class 8 (factory), Class 9a (hospital), 9b (assembly), 9c (residential care) |
| Volume Two -- Housing Provisions | Single/two-family houses + ancillary | Class 1a, 1b, 10a (garage/shed), 10b (fence/wall), 10c (private bushfire shelter) |
| Volume Three -- Plumbing Code of Australia (PCA) | Plumbing + drainage | All classes |
| Class | Description |
|---|---|
| 1a | Single dwelling: detached house or one of attached dwellings |
| 1b | Boarding house, guest house, hostel (low-rise) up to certain size |
| 2 | Multiple dwellings: apartments |

| 10c | Private bushfire shelter |
NCC 2022 is performance-based. Each Performance Requirement (PR) is met via one of:
Performance Solutions are common for fire engineering (FPA Australia accredited), structural engineering, accessibility (alternative routes), energy.
Australia divided into 8 climate zones for energy purposes:
| Zone | Description | Cities |
|---|---|---|
| 1 | Hot humid summer / warm winter | Darwin, Cairns, Townsville |
| 2 | Warm humid summer / mild winter | Brisbane, Gold Coast, Rockhampton |
| 3 | Hot dry summer / warm winter | Alice Springs, Charleville, Tennant Creek |
| 4 | Hot dry summer / cool winter | Mildura, Broken Hill |
| 5 | Warm summer / cool winter | Sydney, Perth, Adelaide |
| 6 | Mild warm summer / cold winter | Melbourne, Canberra (margin), Hobart (margin) |
| 7 | Cool temperate | Canberra, Hobart, Mt Gambier |

Applies to Class 2-9. Performance-based with DTS specifications:
NCC 2022 introduced major tightening of Section J (Volume 1) including:
Nationwide House Energy Rating Scheme:

Australia uses Wind Region map + terrain category:
| Region | Description | Typical Areas | V_R for R = 500 yr (m/s) |
|---|---|---|---|
| A1-A5 | Non-cyclonic | Sydney, Melbourne, Adelaide, Perth metro, Canberra, Hobart, inland | 41-50 |
| A0 | Non-cyclonic, low wind | parts of NT interior | < 41 |
| B | Tropical (lower cyclone) | south-east QLD coast, north NSW coast | 50-60 |
| C | Cyclonic | NT coast, Far North QLD, WA northwest | 70-83 |
| D | Severe cyclonic | offshore areas, North-West Cape | 83-100+ |
Region C + D require cyclonic-resistant construction -- impact-tested glazing, tied-down roofs, robust connections per AS 4055 (Wind Loads for Housing) for Class 1.
Australia is intra-plate with moderate seismicity:
| Material | Code |
|---|---|
| Concrete | AS 3600-2018 |
| Steel | AS 4100-2020 |
| Composite | AS/NZS 2327 |
| Timber (general) | AS 1720.1-2010; AS 1720.2-2006 |
| Residential timber framing | AS 1684 (multi-volumes -- structural design for timber-framed houses) |
| Masonry | AS 3700-2018 |
| Cold-formed steel | AS/NZS 4600-2018 |
| Foundations | AS 2870-2011 (residential slab + footing); AS 3798-2007 (compacted fill); AS 2159-2009 (piles) |
| Wind loads housing | AS 4055-2021 |
| Cyclone loads | AS/NZS 1170.2 Region C + D |
Much of Australia has reactive (expansive) soils -- clay subject to swelling/shrinking. AS 2870 classifies sites Class A (stable) through Class P (problem). Common Class M (moderate) requires footing design accounting for soil movement.
Australia uses building surveyors (private competitive) rather than government building department for most certification. Building surveyor registered with state authority. Responsible for assessing NCC compliance + issuing Building Permits / Construction Certificates + conducting inspections.
