Delayed Retainage Release – Cash Flow Drag
Definition
Retainage (retention) is routinely 5–10% of contract value across Australia. In Queensland, retention must be released within 12 months of practical completion unless otherwise specified. In Western Australia (mandatory from Feb 2024 for contracts >$20k), similar 12-month default applies. However, disputes over project completion, defect liability periods, and head-contract contingencies often extend hold-up periods beyond statutory timelines. Contractors face cash flow stress, especially on large infrastructure projects where retainage equals millions of dollars.
Key Findings
- Financial Impact: 5–10% of contract value held for 6–24 months. For a AUD $100M highway project: AUD $5M–$10M withheld × 1–2 years = AUD $5M–$20M opportunity cost at 8% borrowing cost ≈ AUD $400k–$1.6M annual financing drag.
- Frequency: Every project with retainage; affects 95%+ of Australian construction contracts.
- Root Cause: Manual verification of practical completion; contingent release tied to head-contract events (voided by NSW courts but still common); slow certification workflows; multi-stage trust account compliance.
Why This Matters
The Pitch: Highway and bridge contractors in Australia lose 5–10% of progress billings for 12+ months. A contractor with AUD $10M annual revenue loses AUD $500k–$1M in working capital annually. Digital milestone certification and automated release workflows eliminate hold-ups.
