Aurizon Network is a wholly owned subsidiary of Aurizon Holdings Limited, which was privatised in November 2010 and manages Australia's largest coal export rail network, the central Queensland coal network.

In accordance with Part 5 of the QCA Act, Aurizon Network must allow third-party train operators to use its network.

Applications for access occur in accordance with the process set down in Aurizon Network’s access undertaking, which establishes the framework for access to the coal rail infrastructure in central Queensland.
