Retention on South Australia subcontracts: what's normal, and what to watch

The market-normal position across the subcontracts we've analysed is retention of 5% of the contract sum - typically 10% of each payment until the cap is reached - with half released at practical completion and the balance at the end of the defects liability period. Drafting that holds 10% overall, ties release to the head contract, or restarts the defects period on every rectification is where subcontractors' money gets stuck.

The market position

Median retention in the contracts we've analysed is 5% of the subcontract sum. Ten per cent overall - the position some contracts open with - is double the market and worth pushing back on by that fact alone; subcontractors have negotiated it to 5%, or to two 2.5% bank guarantees in place of cash retention, on exactly that argument.

The stronger ask isn't always the percentage - it's the instrument. Bank guarantees keep the cash in your business; unconditional ones can still be called, but they beat cash deductions for cash flow on every job.

Release: where the real risk hides

Two clauses quietly extend retention past what the percentage suggests. Release tied to the head contract - "on practical completion under the Head Contract" - makes your money wait on a project completion you don't control. And a defects liability period that restarts whenever you rectify a defect can hold the final tranche years past the stated end date.

The positions to ask for: release keyed to your own practical completion and your own DLP, a fixed outside date regardless of rectifications, and release on request rather than on the builder's initiative.

The SA angle

South Australia has no general statutory trust over subcontractor retention - until release, your retention is an unsecured debt owed by the builder, which is why the release mechanics matter more than the percentage.

South Australia follows the NSW template closely with few state-specific traps - disputes usually turn on claim validity and the strength of the builder's payment schedule reasons, and the Small Business Commissioner SA publishes the list of nominating authorities.

Frequently asked questions

Is 10% retention normal on a SA subcontract?

It appears in opening drafts, but it's double the market: median retention across the subcontracts we've analysed is 5% of the contract sum. The 10%-of-each-payment mechanic is normal; the overall cap is what to negotiate.

When does retention have to be released?

When your contract says - which is exactly the problem with drafting tied to the head contract or to a restarting defects period. Market position: half at your practical completion, the balance at the end of your own defects liability period, with a fixed outside date.
