Finding
Your payment is conditioned on the head contractor first being paid by the principal. If money stalls upstream, you carry the cash-flow gap — potentially for months.
Recommended action
Strike the pay-when-paid wording and tie payment to a fixed period after your claim (e.g. 20 business days). In most AU jurisdictions these clauses are void under Security of Payment legislation — flag it.

Why Mason

Better than the alternatives.

A lawyer
Thorough — but heavy
  • Expensive — hundreds per hour, costs add up fast
  • Slow — days or weeks to turn around
  • Hard to justify on every contract that crosses your desk
Best kept for the disputes that really need it.
ChatGPT
Quick — but risky
  • Generic — not trained on construction contracts
  • Can hallucinate clauses, figures and the law
  • No shared record your team can rely on
Fine for a first guess. Not for what you sign.
