Variations on Victoria subcontracts: getting changed work paid
Most variation money is lost between the site conversation and the paperwork. The standard subcontract lets the builder direct variations unilaterally, gives you a short written-notice window (as little as 2 business days in contracts we've analysed) with an absolute bar behind it, and lets the builder value the work where rates don't apply. Since Victoria's 15 April 2026 reforms, disputed variations can generally be pursued in a payment claim and at adjudication - the old claimable-variations restrictions are abolished.
The three clauses that take the money
Unilateral direction: "the subcontractor must comply with all variation orders" - you're bound to do the work before the price is agreed. Positions builders have accepted: variations agreed in writing before they bind, or a cap (bound only within the general scope, up to a stated percentage of the contract sum).
The notice time bar: a direction you consider a variation must be notified in writing inside the window or the claim is lost - 2 business days appears in real contracts. And valuation: "reasonable rates as determined by the Contractor" puts the price of your work in the other party's hands; a schedule of rates incorporated into the contract, sitting high in the order of precedence, is the fix.
The VIC angle
Victoria is the state where the law just moved. For payment claims served from 15 April 2026, the old excluded-amounts and claimable-variations regimes are abolished - disputed variations, damages and time-related costs can now generally be included in a payment claim and pursued at adjudication. Pre-reform advice that variations couldn't be adjudicated in Victoria no longer applies to new claims.
The 90-second habit
Before leaving site on the day anything changes: one email. "Confirming we discussed [the change] on site today. We're treating this as a variation. Formal notice and pricing follow within the contractual timeframe. Work proceeds on that basis unless you advise otherwise." It anchors the date, creates the record, and starts you inside whatever window the contract sets.

Under standard drafting, yes - the direction binds first and valuation follows. That's why the pre-signature ask is a written-agreement requirement or a cap, and the on-site protection is same-day written confirmation of every direction.
Yes - for claims served from 15 April 2026, the reformed Act generally allows disputed variations in a payment claim and at adjudication. The old restrictions are abolished.
