The concentration of phosphine residue in grain post fumigation (where it is currently being measured) that poses no risk to workers is unknown. The SWA TLV-TWA is soon to be reduced to 0.05 ppm. Continuing current practices could result in the loss of phosphine as a registered stored grain fumigant and there is an urgent need to optimise post-fumigation protocols. This investment will address this by delivering: * Data packages required to update the phosphine label registration with the APVMA, including appropriate ventilation and withholding periods to reduce phosphine residue in grain to thresholds that meet SWA worker exposure limits. * A new or updated Australian standard for phosphine fumigation, including an agreed protocol of how phosphine residue in grain should be measured at receival sites to meet the SWA TLV-TWA, and appropriate clearance thresholds. * An on-farm protocol for growers to measure phosphine residue prior to outturn, to ensure residues are below thresholds set in the above standard.

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.
