Regulatory standards for gas installations

Australian Standards are issued under licence from Standards Australia. Visit the Standards Australia website to purchase a copy of any Standards.

Changes to AS/NZS 5601: Transition Ends 6 March 2025

Amendment 2 was released on 6 September 2024 for both AS/NZS 5601.1:2022 (Gas Installations – General Installations) and AS/NZS 5601.2:2020 (LP Gas installations in caravans and boats for non-propulsive purposes).
