On 30 July 2008, the ACCC accepted ARTC’s Interstate Access Undertaking (IAU). The IAU sets out the principles and processes under which ARTC, as an infrastructure provider of rail, will be obliged to provide access to businesses wishing to run trains on ARTC’s interstate rail network.
The interstate rail network covers the mainline standard gauge track linking Kalgoorlie in Western Australia, Adelaide, Wolseley and Crystal Brook in South Australia, Melbourne and Wodonga in Victoria and Broken Hill, Cootamundra, Albury, Macarthur, Moss Vale, Unanderra, Newcastle (to the Queensland border) and Parkes in New South Wales (NSW).
On 18 July 2008 Australia Post lodged a locality notice under subsection 95Z(5) of the Trade Practices Act 1974. This locality notice proposed increases in prices of Australia Post's reserved letter services.
