2016 Access Undertaking (UT4)

  • Approved Access Undertaking
  • Variations
  • Ongoing Compliance

The 2016 access undertaking sets out the process required for an access seeker to negotiate access to the infrastructure, and how any disputes in relation to access are to be resolved.

Aurizon Network is obliged to undertake a number of activities in accordance with its undertaking, some of which require the QCA's approval (e.g. annual approval of capital expenditure, revenue cap adjustments and reference tariff variations).

Aurizon Network can seek to amend an approved undertaking by submitting a draft amending access undertaking, in accordance with the process set out in the QCA Act.

Aurizon Network's 2016 access undertaking and relevant standard agreements, as approved by the QCA, are found below. Other explanatory material related to the approved undertaking is located in our final decision on the 2014 Draft Access Undertaking (DAU).
