What these values mean

Each amount is the reported full contract value, including GST where applicable, in nominal Australian dollars. It covers the reported contract period. It is not annual expenditure, cash paid, all government spending or spending in a supplier’s local area. Unexercised future options are not necessarily included.

This snapshot includes every notice in 82 consecutive weekly exports, covering 2 March 2025 to 26 September 2026, retrieved 1 October 2026 (UTC date). AusTender lists only about eighteen months of exports, so weeks before 23 March 2025 are kept from our earlier downloads. Each contract contributes its latest observed version once. Earlier versions remain available in its history; values of successive amendments are never added together. Date filters use that latest observation’s publication date, including amendments, not the contract start date.

Weekly files describe information at extraction. Later corrections, cancelled notices, or contracts with no publication in this archive may be absent. This is not the entire historical AusTender register. Some source timestamps fall just outside their file’s labelled week; their reported dates are retained. Three malformed observations have shifted columns; affected supplier/category fields are marked unavailable. Source dates in 1900 or end dates in the next century are flagged, not interpreted as ordinary durations.

Supplier grouping uses reported ABNs with a valid checksum; it is not independent verification against the business register. Missing or invalid ABNs remain separate by contract. Equal names do not establish equal legal entities. A contract award is not evidence of wrongdoing.
