The Fuel Quality Standards Amendment Determination (No. 1) 2026, registered on March 24, 2026, amends the existing Fuel Quality Standards (Conventional Diesel) Determination 202. This legislative instrument, authorized by the Fuel Quality Standards Act 2000 and administered by the Department of Climate Change, Energy, the Environment and Water, introduces specific changes to the standards applicable to conventional diesel fuel.

Entities involved in the importation, manufacturing, or retail of conventional diesel fuel in Australia must review and comply with the updated standards outlined in the amendment. While the document does not specify an immediate compliance deadline beyond its effective date, adherence to these revised fuel quality standards is mandatory. Non-compliance could lead to regulatory action under the Fuel Quality Standards Act 2000.
