Security of Payment in the Australian Capital Territory: the deadlines a subcontractor works to

Every date below comes from the Building and Construction Industry (Security of Payment) Act 2009 (ACT), and each one shows the section it comes from so you can check it. The contract can set an earlier date than the Act in places, and the Act wins where the contract is later than it allows.

For the actual dates on your claim, put the day you served it into the deadline calculator.

Which days are not business days under the Security of Payment Act in the Australian Capital Territory?

Weekends and public holidays, and the Act itself takes out 27 December to 31 December (ACT Dictionary (business day)).

Not legal advice. These are statutory defaults. Verify every date against the relevant Security of Payment Act and your contract.

Business-day counting excludes weekends, the Act-specific December/January shutdown, New Year’s Day, Australia Day, Good Friday, Easter Monday, Anzac Day, Christmas Day and Boxing Day, plus the substitute weekday where New Year’s Day, Australia Day, Christmas Day or Boxing Day falls on a weekend. Anzac Day is substituted in Queensland when 25 April falls on a Sunday, as it is in the Australian Capital Territory and the Northern Territory, and in Western Australia when it falls on either a Saturday or a Sunday. State and territory public holidays are modelled for New South Wales, Queensland, Victoria, Western Australia, South Australia, Tasmania, the Australian Capital Territory and the Northern Territory. State public holidays counted here: Canberra Day, Easter Saturday, Easter Sunday, Anzac Day (observed), Anzac Day (declared Monday), Reconciliation Day, King’s Birthday, Labour Day. Not counted: any extra public holiday the ACT Minister declares by notice in a later year, such as the Monday after a Saturday Anzac Day, which was declared for 2026 only. A deadline near it can fall a day later than shown.

On a real job, you do not type any of this

YourCA reads your head contract, works out the dates it puts on you and warns you before each one closes: claim day three days out, a variation notice window two days before it shuts, their payment schedule the day it is late. Every figure shows the clause it came from.
