AS 1428.1:2021 is a newer edition than AS 1428.1:2009, but project teams must not assume the newest publication automatically applies to every approval. The applicable edition depends on the NCC adoption and project approval context.
Because access requirements are project-specific, the correct answer depends on the building, proposed work, approval pathway and evidence available. This guide explains the practical questions to ask before making a decision.

The key factors
- Terminology, figures, dimensions and explanatory material may differ between editions
- A detail compliant under one edition should not be assumed compliant under the other
- Drawing notes and specifications must identify the intended edition consistently
- Product selections and standard details should be checked against project-specific criteria
- Transitions between design, approval and construction dates can create documentation confusion
A qualified access consultant can help connect these factors to the relevant NCC provisions, Premises Standards, Australian Standards and project documentation. The review scope should identify the criteria being applied and any important limitations.
Common mistakes
Changing editions mid-project without review, copying old standard details, mixing figures from two editions, relying on memory instead of the actual standard, or stating compliance without confirming the approval basis.
These mistakes are easier to correct in drawings and project planning than after approval, procurement or construction. Early review also gives the architect, building surveyor, owner and contractor a shared record of the issue.
A practical way forward
- Confirm the applicable NCC edition and referenced standards with the building surveyor
- Record the selected edition in the access brief and documentation
- Review affected standard details rather than updating only general notes
- Seek specialist advice where an edition change affects a material design decision
What useful advice should contain
A useful assessment should state the purpose of the review, the documents or areas assessed, the applicable criteria, material findings, assumptions, exclusions and recommended next actions. It should be written for the people who need to resolve the issue, rather than simply reproducing clauses.
Where a design changes after the assessment, the affected access findings should be reviewed again. One altered doorway, level, fixture or route can affect connected parts of the accessibility strategy.

Frequently asked questions
Should I wait until the design is complete?
No. Early advice usually provides more options and reduces the chance of redesign. The scope can be updated as documentation develops.
Does an access consultant replace the building surveyor?
No. The access consultant provides specialist advice. The building surveyor or relevant authority remains responsible for statutory approval decisions.
What should I send ASN?
Send the address, project description, current drawings or photographs, project stage, question to be answered and required date. ASN will confirm the appropriate service and scope.
