Telstra Corporation Limited has notified the Australian Competition and Consumer Commission of an access dispute with Optus Mobile Pty Limited and Optus Networks Pty Limited, under Part XIC of the Trade Practices Act 1974. The dispute relates to the price paid by Telstra for the Domestic Mobile Terminating Access Service supplied by Optus by means of its mobile networks, for 2006. The ACCC has commenced the arbitration process for this access dispute. Given that the legislation contemplates that arbitrations be conducted in private, the ACCC will not be making any public comment at this stage.
