In effect
Aurizon Network’s approved 2017 access undertaking provides for it to apply, at any time, to vary reference tariffs in response to an endorsed variation event or a review event.
Endorsed variation event—QCA levy, 2022–23
Aurizon Network’s July 2022 proposal to adjust reference tariffs for 2022–23 to reflect the QCA’s fee estimates for the provision of regulatory services in 2022–23 and confirmation of its final regulatory fees for 2021–22.
We approved the proposal and published our decision on 25 August 2022. The revised reference tariffs took effect on 1 September 2022.

Endorsed variation events—AT5 reference tariff and QCA levy, 2020–21
On 17 July 2020, Aurizon Network applied to adjust reference tariffs for 2020–21 as a result of two endorsed variation events. Aurizon Network sought a change to the AT5 tariff arising from a change in the pricing from a transmission entity, and a change to the QCA levy associated with a variation in the QCA fees.
We were satisfied in both cases that the requirements for an endorsed variation event were met and approved the applications on 20 August 2020. The revised reference tariffs took effect on 1 September 2020.
