Does Australia have an AI law?

No. In December 2025 the National AI Plan confirmed Australia would not introduce a standalone AI Act or the mandatory guardrails proposed in 2024. AI is regulated through existing laws such as the Australian Consumer Law, the Privacy Act, workplace law and anti-discrimination law, supported by voluntary guidance.

Can I use AI in my construction business without any restrictions?

No. There is no AI-specific law, but existing laws still apply. You are responsible for what an AI tool produces, including quotes, client communications and decisions about staff. A person should review anything that affects price, scope, safety or employment.

What are the six essential practices in the Guidance for AI Adoption?

They are: decide who is accountable, understand impacts and plan accordingly, measure and manage risks, share essential information, test and monitor, and maintain human control. The guidance was published by the National AI Centre on 21 October 2025 and is voluntary.

What changes on 10 December 2026?

Businesses covered by the Privacy Act must state in their privacy policy when they use automated decision-making that could significantly affect people, including the kinds of personal information used and whether decisions are fully automated or substantially assisted by AI.

Do I need to follow the voluntary AI guidance if it is not law?

It is not required and following it is not a legal defence on its own, but it is a sensible benchmark. Having a named owner, an approval rule and a list of the tools you use puts you in a much stronger position if something goes wrong.

Australia's AI Rules for Construction Businesses: What Applies in 2026

There is no AI Act in Australia, and the proposed mandatory guardrails were dropped. That does not mean anything goes. Here is what actually applies to a construction business using AI, and a simple checklist.

Last checked 6 October 2026. This is general information for business owners, not legal advice. Talk to a lawyer about your specific situation.

If you run a construction business and you have started using AI for quotes, emails, site notes or reporting, you have probably wondered what the rules are. The honest answer is that Australia has no AI-specific law, and that is a deliberate decision. But "no AI Act" is not the same as "no rules".

What happened, in short

September 2024: the government proposed ten mandatory guardrails for high-risk AI.
21 October 2025: the National AI Centre published the Guidance for AI Adoption, six practices for using AI responsibly. It is voluntary, and it replaces the earlier Voluntary AI Safety Standard as the main practical guide.
December 2025: the National AI Plan confirmed Australia would not introduce a standalone AI Act or the mandatory guardrails. Instead it relies on existing laws, existing regulators, voluntary guidance and a new AI Safety Institute, funded at $29.9 million and rolling out through 2026.

What that means for a builder

The rules that already existed still apply to AI. If an AI tool causes harm, you are judged under the same laws you already live with:

Australian Consumer Law: misleading quotes, claims or conduct are still misleading if an AI wrote them.
The Privacy Act: client details you put into an AI tool are personal information, and you remain responsible for them.
Work health and safety and workplace law: using AI to monitor, roster or manage workers does not change your duties to them.
Anti-discrimination law: automated decisions about people can still be discriminatory.

The practical point is that "the AI did it" is not a defence. You own the output, so you need a person checking anything that matters.

One date to know: 10 December 2026

From 10 December 2026, businesses covered by the Privacy Act must say in their privacy policy when they use automated decision-making that could significantly affect people's rights or interests, including the kinds of personal information used and whether decisions are fully automated or substantially assisted by AI. The Privacy Act generally covers businesses with annual turnover above $3 million, and some smaller ones. The privacy regulator, the OAIC, has said it will be proportionate and is still developing its guidance.

For most builders using AI to draft emails or summarise site notes, this is unlikely to be triggered. It matters if AI starts making or heavily shaping decisions about people, such as screening job applicants, assessing clients for credit, or allocating work to staff. If that is on your roadmap, update your privacy policy first.

The six practices, translated for a construction business

The Guidance for AI Adoption sets out six essential practices. It also has a "foundations" version for businesses that are early in their use of AI, which is where most builders are. Here is what each one looks like in practice.

1. Decide who is accountable

Name one person for each AI tool you use. If the quote assistant sends something wrong, who owns that? In a 20-person business it is usually the owner or the office manager. Write the name down.

2. Understand the impacts

Ask who is affected if the tool gets it wrong: clients, staff, subcontractors, suppliers. A tool that drafts internal meeting notes has a small impact. A tool that sends pricing to clients has a large one.

3. Measure and manage the risks

For each tool, write down the worst realistic thing that could happen and what stops it. For example, "wrong price sent to a client" is stopped by "a person approves every quote before it goes out".

4. Share essential information

If clients are dealing with an AI assistant, for example a chat widget or an automatic first reply, make that clear. Do not let people believe they are talking to a person when they are not.

5. Test and monitor

Try a tool on real examples before relying on it, then spot-check it regularly. AI tools change when the vendor updates them, so a tool that was reliable in March may behave differently in September.

6. Keep a human in control

The more autonomy a tool has and the higher the stakes, the more human oversight it needs. A simple rule that works for builders: AI can draft, a person approves anything that affects price, scope, safety, or someone's employment.

A simple checklist for a 10 to 50 person builder

List every AI tool anyone in the business uses, including free ones staff signed up to themselves.
Decide what client and staff information may and may not go into them. As a baseline, do not put client personal details into free public tools.
Name an owner for each tool.
Set the approval rule: what a person must always review before it is sent or acted on.
Tell clients when they are dealing with an automated assistant.
Check your privacy policy, and plan for the December 2026 change if AI influences decisions about people.
Review the list twice a year.

Is the guidance a legal defence?

No. The Guidance for AI Adoption is voluntary and is not law, and following it does not protect you on its own. It is best read as a benchmark of what careful, responsible use looks like. If something does go wrong, being able to show that you named an owner, had an approval rule and checked the tool is far better than having nothing in writing.

Could mandatory rules come back?

Possibly. Policy can change, and a high-profile incident can change it quickly. Building simple habits now, such as an owner, an approval rule and a tool list, means you will not be scrambling if the rules tighten.

How we approach it

When PlanDepa builds AI into a construction business, we design around the sixth practice from the start: AI drafts and flags, and a named person approves anything that affects price, scope, safety or people.
