In South Australia, a payment claim under the Building and Construction Industry Security of Payment Act 2009 must identify the work, goods or services, state the amount claimed and state that it is made under the Act. Check scope first, because the Act does not cover domestic building work on premises where the client lives or intends to live. Make the claim within the later of the contract period or 6 months after the last work or supply, and get advice on valid service for your case.[1][2]
Check the Act applies first
The Act applies to written or oral construction contracts. It excludes domestic building work on premises where the client resides or intends to reside, work outside South Australia and other listed cases. If your job is a home renovation for an owner-occupier, do not assume this process is available.

What the claim must contain and when it can be made
The right to a progress payment arises on a reference date. The contract can set reference dates and the Act supplies a default where it does not. A claim must identify the construction work, goods or services, state the amount claimed and state that it is made under the Act.
You can make one claim for each reference date, and it can include earlier amounts. It must be made within the later of the period in the contract or 6 months after the last work or supply.
Schedule date and payment due date are different
The respondent's payment schedule is due by the earlier of the time in the contract or 15 business days after service. Payment itself is due on the date the contract sets or, where the contract has no express provision, 15 business days after the claim. Record both dates separately.
The Act's business day excludes weekends, public holidays and 27 to 31 December. Count them that way and do not mix them with calendar days.
| Item | What the Act says | What to record |
|---|---|---|
| Claim content | Identify the work, state the amount, state it is made under the Act | Work description, amount, wording used |
| Claim window | Later of the contract period or 6 months after last work or supply | Last work or supply date and contract clause |
| Frequency | One claim for each reference date | Reference date used |
| Payment schedule | Earlier of the contract time or 15 business days from service | Service date and both dates compared |
| Payment due | Contract date or, if none expressed, 15 business days after the claim | Contract clause or default used |

What this guide does not cover
This guide does not cover valid service, suspending work or adjudication timing. Those depend on your contract and facts, so get timely advice. If the Act does not apply to your job, a contractual process or a letter of demand may be the route to look at instead.
