The Australian Competition and Consumer Commission today published final determinations for four access disputes relating to the Mobile Terminating Access Service.*

The decisions were made on 20 December 2007 and were published following a compulsory legislative consultation period on publication.

The disputes relate to the charges payable for carrying the portion of a call which terminates on Optus's and Telstra's mobile networks. The final determinations set out the charges to be paid by Telstra and Optus to each other for the supply of the MTAS in 2007.

The period for these final determinations spans both the expired MTAS Pricing Principles which are relevant for the period 1 July 2004 to 30 June 2007 and the recently released MTAS Pricing Principles Determination for the period 1 July 2007 to 31 December 2008. These are the first final determinations to apply the MTAS Pricing Principles Determination for the period 1 July 2007 to 31 December 2008.

The terms of the final determinations include a price for the MTAS of 12 cents per minute from 1 January 2007 to 30 June 2007 and a price of 9 cpm from 1 July 2007 to 31 December 2007.

The decisions in these access disputes only have effect between Telstra and Optus.

The final determinations and supporting statements of reasons will be available on the ACCC's website.
