The QLD BIF Act Explained Simply for Tradies

Queensland’s Building Industry Fairness (Security of Payment) Act 2017 — the BIF Act — is one of the most important pieces of legislation for tradies and subcontractors in Queensland. If you’re working in construction in QLD and you’re owed money, this is the law that can get you paid fast. Here’s the BIF Act explained simply, without the legal jargon.

Why Was the BIF Act Introduced?

Queensland’s BIF Act replaced the older Building and Construction Industry Payments Act 2004 to strengthen protections for subcontractors and suppliers. The Queensland government recognised that payment disputes and insolvencies in construction were causing enormous harm to small subcontractors and tradies — and that stronger laws were needed.

The BIF Act introduced several improvements, including project bank accounts for certain government projects, stronger adjudication processes, and clearer obligations on head contractors to manage subcontractor payments.

What Does the BIF Act Actually Do?

In simple terms, the BIF Act:

1. Gives you a right to claim: You have a statutory right to serve a payment claim on the party above you in the contract chain at each reference date. This is not just asking for money — it’s triggering a legal process with real consequences for the other side.
2. Forces a response: The head contractor or principal must respond to your payment claim within 15 business days with a payment schedule that either confirms payment or formally disputes specific items.
3. Creates consequences for non-response: If the head contractor doesn’t issue a payment schedule, the full claimed amount is legally owed to you. You can apply for adjudication or go to court to recover it.
4. Provides fast adjudication: If your claim is disputed, an independent adjudicator reviews both sides and makes a binding determination — typically within 10 business days.
5. Makes determinations enforceable: An adjudication determination can be filed as a court judgment and enforced against the head contractor.

Who Can Use the BIF Act?

The BIF Act covers anyone with a “construction contract” for work in Queensland. This includes:

• Subcontractors of all trades — including electricians, plumbers, concreters, roofers, carpenters, plasterers, painters, and many more
• Suppliers of building materials and equipment
• Consultants and design professionals
• Labour hire providers supplying workers to construction sites

Key Timeframes Under the BIF Act

• When to serve a payment claim: On or after the reference date in your contract (usually monthly or at project milestones)
• Payment schedule deadline: 15 business days after the payment claim is served
• Adjudication application deadline: 30 business days from receiving the payment schedule (or when it was due)
• Adjudication decision: Within 10 business days of the adjudicator accepting the application (or 15 if extended)

What About Project Bank Accounts?

The BIF Act introduced project bank accounts (PBAs) for certain large government-funded projects in Queensland. PBAs require head contractors to hold subcontractor payment funds in a protected trust account, significantly reducing the risk of subcontractors being unpaid if the head contractor experiences financial difficulty. PBAs are an additional layer of protection on top of the SOP adjudication process.
