AI subcontract review software in Australia, compared
AI subcontract review software reads a construction subcontract and flags the clauses that move risk onto you. There are four ways to get one done in Australia: a free purpose-built scanner, a paid subscription platform, a general AI chatbot, or a construction lawyer. They differ most on price, on whether the review is grounded in your state's Security of Payment Act, and on whether it uses real market data.

AI risk report, not legal advice. The scanner gives general information about the risks in a document. It is not a lawyer, does not know your circumstances, and can be wrong. For decisions with legal consequences, get advice from a construction lawyer.
Side by side
| Question | Subcontract Risk Scanner (free) | Paid subscription (SubSync) | General AI chatbot | Construction lawyer |
|---|---|---|---|---|
| Price | Free. No account, no card, up to 30 scans a month. | SubSync: free plan with 1 review in total, then $175, $265 or $355 a month for 2, 5 or 10 reviews, extra reviews $115 each (AUD incl GST, as published 9 October 2026). | Free or a monthly subscription. | A few hundred dollars for a quick read, up to several thousand for a full markup. |
| Time to a result | About two minutes. | SubSync states 15 to 20 minutes for a commercial review. | Minutes, but you write the questions. | Usually days. |
| Grounded in your state's Act | Yes. All eight states and territories, from a registry checked against current legislation, including the April 2026 Victorian reforms. | SubSync publishes Security of Payment guides for NSW, VIC and QLD. | Only what it remembers or you paste in. Deadlines can be out of date or wrong. | Yes. |
| Market data | Every finding is benchmarked against the Australian Subcontract Index, 90 real Australian subcontracts, with sample sizes shown. | SubSync benchmarks against "typical Australian commercial positions". | None. | The lawyer's own experience. |
| Drafts the changes | Departure schedule spreadsheet, cover email to the builder, and reminders for the dates the contract fixes. | SubSync drafts a departure schedule, plus contract notices and purchase orders on paid plans. | If you ask, with no check against the contract. | Yes, and can negotiate for you. |
| When the job goes wrong | Adjudicate Pro, free: simulates an adjudication under your state's Act and what would sink the application. | SubSync drafts EOT, variation, payment, suspension and defects notices. | General answers. | Full representation. |
| Legal advice | No. AI risk report. | No. SubSync states it is not a law firm. | No. | Yes. |
Where a paid platform fits: if you want notices, purchase orders and claims managed in one subscription, a platform like SubSync bundles them. If you want the review itself, the scanner does it free on every contract.
Six questions to ask any AI review tool
- Which state's Act does it check against, and when was that checked? Victoria changed its Act on 15 April 2026, and WA runs two regimes depending on the contract date.
- Does it compare clauses with real Australian contracts, and does it show the sample size?
- Does every finding quote the clause it came from, so you can check it?
- Does it draft the change to ask for, or only describe the problem?
- Where is your contract stored, for how long, and is it used to train a model?
- What does it cost per contract once the free trial ends?
The scanner's answers are public: security and data handling, how the AI is used and tested, and the live Index it benchmarks against. Prefer to check the clauses yourself? Use the subcontract review checklist.
Common questions
What is AI subcontract review software?
Software that reads a construction subcontract and flags the clauses that move risk onto the subcontractor, such as payment terms, liquidated damages, time bars, set-off and retention. Better tools check those clauses against the state's Security of Payment Act and market data, and draft the changes to ask for.
Is there free AI subcontract review software in Australia?
Yes. The Subcontract Risk Scanner from The Construction Contracts Co. is free with no account and no per-review charge. It covers all eight states and territories, benchmarks every finding against the Australian Subcontract Index, and drafts a departure schedule and cover email.
Can I just use ChatGPT to review a subcontract?
You can, but a general chatbot doesn't know your state's current Security of Payment rules unless you tell it, has no data on what Australian subcontracts actually say, and can state wrong deadlines confidently. Check its privacy settings before uploading a contract. A purpose-built tool grounds the review in the Act and real contract data.
Is AI contract review legal advice?
No. AI review tools give general information about the risks in a document. For large exposures, deeds and guarantees, design responsibility or live disputes, use a construction lawyer. A scan first makes that lawyer quicker and cheaper.
