Australia
Australia has arguably the most mature statutory payment-protection framework of any market in this vault. Security of Payment (SOP) legislation was first introduced in New South Wales in 1999 and now exists in every Australian state and territory. The Acts give contractors, subcontractors, consultants and suppliers a statutory right to make progress payment claims, oblige recipients to respond or pay within mandated timeframes, void Pay-When-Paid Clauses, and — critically — cannot be contracted out of. They are the reference implementation of Prompt Payment Legislation that other markets, including South Africa and Canada, have studied or copied.

The defining feature is fast statutory Construction Adjudication: a payment dispute is decided on an interim-binding basis within short statutory timeframes (roughly 10–15 business days in NSW), at a fraction of the cost of court or arbitration. Decentralisation is a notable weakness — SOP is not a federal law, so timelines, claim requirements and adjudication procedures vary by jurisdiction (in WA and the NT the statute is styled the Construction Contracts Act), creating an uneven national picture.

Crucially for the vault’s thesis, Australia is evidence that strong law does not abolish the payment problem. Reform has continued precisely because abuse persisted: Western Australia replaced its regime with the Building and Construction Industry (Security of Payment) Act 2021, and in 2023 a Victorian parliamentary committee ran a full inquiry into “employers and contractors who refuse to pay their subcontractors for completed works”, foreshadowing fundamental changes to the Victorian SOP Act. That an inquiry into subcontractor non-payment was needed two decades after the model was introduced is a significant data point: statutory adjudication compresses delay and gives subcontractors a remedy, but does not eliminate the underlying behaviour.
