Most of the new provisions of NCC 2022 took effect on 1 May 2023 in all states and territories across Australia.
There are three changes that affect linings, as follows:
- A new structure and clause referencing system has been implemented to make NCC 2022 more web accessible.
- Fire safety of external walls - Non-combustibility requirements for attachments and linings of external walls has been clarified.
- Weatherproofing - Volume One contains additional DTS Provisions, including reference to AS 1562.1 as an acceptable solution for weatherproofing of external metal wall sheeting.
NCC 2022 clause numbering system
NCC 2022 uses a new structure and clause referencing system to make it more web accessible.
Unfortunately, this means all the clause numbers you might have memorised have now changed. To help you, below is a cross-reference guide to help you find the new clause reference number from the old clause numbers:

The NCC uses a uniform clause numbering system across each of its three volumes. This system is called Section-Part-Type-Clause (SPTC).The letters used in the clause numbering system indicate the following:
S = Specification (a high-level overview)
G = Governing requirement (mandatory)
O = Objective (guidance)
F = Functional Statement (guidance)
P = Performance Requirement (mandatory)
V = Verification Method (optional)
D = Deemed-to-Satisfy Provision (optional)
C = Clause in a Specification (clauses in Specifications may be mandatory or optional, depending on how the Specification is called up by the NCC).
Above is an extract of the cross-reference guide, showing the new Clause reference number from the old Clause numbers, relating to internal linings.
As an extra bonus, we have added some notes and the page numbers.
