Australia's Security of Payment (SOPA) legislation gives subcontractors and head contractors a statutory right to progress payments — and to recover money owed through a fast, low-cost adjudication process if payments are disputed or withheld.
The legislation varies by state and territory. NSW uses the SOPA 1999, Victoria uses SOPA 2002, Queensland has its own BIF Act 2017, while Western Australia and the Northern Territory operate under the Construction Contracts Act (CCA) framework — with different deadlines, day-counting rules, and enforcement bodies in each jurisdiction.
Getting deadlines wrong can void your statutory rights entirely. These tools are designed to help you calculate the critical dates quickly and accurately, and generate a compliant payment claim document — so you can focus on chasing the money, not the paperwork.
Not legal advice. SOPAHub tools provide general information based on publicly available legislation. Deadlines, calculations, and documents should be verified with a qualified construction lawyer before serving. If your claim involves significant sums or a disputed contract, consult a specialist. Legislation changes — always check for recent amendments in your state.
If your payment dispute involves a significant amount or a contested contract, a specialist construction lawyer can advise on your rights, draft correspondence, and represent you in adjudication or court.
