The proposal puts a number on a debate the industry has been having in general terms for two years. Whether it would reduce the amount a builder needs to know, or simply move it somewhere else, depends on detail that does not exist yet.

Speaking at the National Press Club in Canberra on Wednesday 12 August 2026, opposition housing spokesman Andrew Bragg committed a future Coalition government to replacing the National Construction Code with a far shorter document of roughly 80 pages, which he called the Basic Australian Standard.

Under the proposal, structural requirements, fire safety and health related provisions would remain mandatory. Most other requirements, including accessibility features and energy efficiency standards, would become optional inclusions a buyer could elect to pay for or leave out. A federal pattern book of approved house templates would sit alongside the shorter standard.

Nothing changes on site today. The Coalition is in opposition and the next federal election is not due until 2028. The proposal matters for a different reason. It puts a specific number on an argument the industry has been running in general terms since the last code cycle, and it lands in the middle of a review the current government already has underway.

What the code actually looks like now

Treasury’s December 2025 discussion paper on streamlining the code sets out the baseline. The NCC runs to around 2,000 pages and references more than 100 separate standards. Of those 2,000 pages, 600 are given over to state and territory variations.

Reporting on the speech puts the total higher, at just over 2,200 pages once every building class is counted, with more than 700 pages of variations. Evidence given to the Senate Select Committee on Productivity in Australia, which Senator Bragg chairs, put the portion of the code dealing with a standard house at 332 pages.

Those figures do not need reconciling so much as understanding. Page counts move depending on which volumes, appendices and jurisdictional schedules are included, and whether plumbing is counted alongside building. What is not in dispute is that the document has grown across successive editions, and that it has grown for two distinct reasons.

The first is expanded scope. Recent editions brought in a seven star energy efficiency requirement and mandatory accessibility provisions, which are policy choices layered onto a technical document.

The second reason is one every builder will recognise, and it complicates the argument considerably. Alongside the performance requirements, the code now carries far more explanatory material. Diagrams. Worked examples. Guidance on how to actually satisfy a clause rather than a bare statement of what the clause requires. That material adds pages. It also removes guesswork, and it is the part of the code that certifiers and builders lean on most.

Page count is not the same thing as compliance burden

This is the part of the proposal that deserves the closest reading, and it has almost nothing to do with politics.

New Zealand is the reference point for the 80 page target, and the New Zealand Building Code genuinely is short. It sits in Schedule 1 of the Building Regulations 1992 and is written as objectives, functional requirements and performance criteria. Read on its own, it is a slim document.

But that document is not what a New Zealand builder works from. Compliance is demonstrated through a separate library of acceptable solutions and verification methods, published clause by clause, which in turn reference New Zealand and Australian standards. The acceptable solution for structure alone covers houses and small buildings in timber, steel, masonry and earth.

So the total volume of technical material a New Zealand builder has to satisfy is not 80 pages. It is a short code plus a long shelf of supporting documents.

Australia could restructure the same way, and there is a reasonable case for it. Splitting the NCC into a short performance code and a separate set of deemed to satisfy documents is a legitimate reform with real benefits for how the code is drafted, updated and searched. What it would not do is reduce the compliance obligations builders already carry. It would change where the information sits.

The word to watch is optional

The more consequential part of the proposal is not the page count. It is the shift from mandatory to optional.

The case for it is straightforward. Buyers who do not want to pay for a particular feature should not be compelled to, and every mandated inclusion narrows the range of what can legally be built at the affordable end of the market. On this reading, a minimum standard should establish that a house is structurally sound, will not burn and is safe to live in, and stop there.

The case against is equally straightforward. Social services groups and standards bodies argue that energy performance and accessibility are not amenities but determinants of running costs, health and whether a home stays usable as an occupant ages. Making them optional, on this reading, does not remove a cost. It defers it onto the household and onto the housing stock.

For builders there is a third question underneath both positions, and it is practical rather than ideological.

An optional standard is a specification decision, and specification decisions have to be quoted, documented, signed off and sometimes defended. A code minimum takes an argument out of the sales process because it is not negotiable. An optional inclusion puts that argument back in, at quote stage, at variation stage and potentially at handover. Every one of those choices has to be priced into a residential building contract and evidenced later.

There is a market question too. If two houses completed in the same year carry materially different energy performance because one buyer opted out, then lenders, insurers, valuers and future purchasers all have to learn to read that difference. At present they do not have to, because the floor is the floor.

Any version of this runs through the states

The Commonwealth does not regulate the built environment. The NCC only has legal effect once a state or territory adopts it into its own regulations, and jurisdictions can and do vary provisions to suit local conditions. That is precisely why 600 pages of the current code are variations.

Treasury’s Inspector General of Housing made the same point to Senate estimates earlier this year, describing Australia as operating not one national construction code but eight separate construction regulatory systems depending on which side of a border you happen to be standing on.

An 80 page federal standard is therefore not something a federal government can simply issue. Every state and territory would have to repeal or rewrite what it currently adopts and take up the shorter instrument instead. Any jurisdiction that declined would keep its existing requirements, and the national picture would fragment further rather than converge.

That constraint is not unique to the opposition’s proposal. It applies with equal force to the reform program the current government is running, and it deserves the same scepticism in both directions.

What is already in motion

Three processes are running concurrently, and the proposal has to be read against all of them.

First, residential changes to the NCC are paused until mid 2029, agreed by Building Ministers on 22 October 2025 and carved out for safety and quality measures.

Second, Treasury is running a modernisation project built on four themes: governance and process, complexity and regulatory burden, usability, and innovation and housing diversity. Submissions closed on 27 February 2026 and the government has said the outcome will go to building ministers this year.

Third, the Productivity Commission released an interim report on housing supply regulation in July 2026, setting out four principles for a better system: adopt a build mindset, regulate only where necessary, coordinate housing with infrastructure, and keep the process simple. Its final report is due to government in early 2027. Notably, the Commission identified zoning and land use controls, rather than building regulation, as the area where reform would do most to lift supply.

Senator Bragg’s own Senate Select Committee on Productivity in Australia, established on 4 November 2025, is due to report by 30 September 2026. That report is the likelier place to find the detail the speech did not supply.

The sector’s peak residential body responded to the speech by welcoming the principle while noting that whether the final residential code runs to 80 pages or some other number matters less than untangling the layers of complexity sitting beneath it. That is a fair reading of the problem, and it is also an admission that the headline number is the least useful part of the proposal.

The Good Builder Take

The page count is the headline. The structure is the story.

A shorter code is not automatically a simpler one. If 2,000 pages become 80 pages plus a separate shelf of deemed to satisfy documents, the reading load does not fall, it relocates, and the arguments about interpretation move with it. If 2,000 pages become 80 pages and nothing else, then the guidance that currently tells a builder how to satisfy a clause disappears, and the risk of getting it wrong shifts onto the builder and the certifier.

The reforms most likely to change a working week are the ones nobody puts in a speech. Fewer variations between jurisdictions. Free access to the standards the code references. A document that can actually be searched on a phone standing in a frame. Those were the things industry raised with Treasury, and none of them require an argument about what a house should include.

Where this leaves builders

The current code applies unchanged. NCC 2025 is in force, with adoption dates varying by jurisdiction, and the residential pause runs to mid 2029. No specification, no quote and no contract needs revisiting because of a speech.

What has shifted is the policy debate builders operate inside. Until this week the question in front of the industry was how to simplify the code that exists. The Coalition has now put a different question on the table, which is what the code is for in the first place: a minimum standard establishing that a house is safe, or an instrument for setting national policy on energy, accessibility and amenity.

That is a much bigger question than 2,000 pages against 80. It is also the one that will determine what a new home in Australia is required to include for the next decade, and it will be settled by state and territory building ministers rather than by anyone at a lectern in Canberra.
