The ACCC held a public inquiry under subsection 152AL of the Trade Practices Act 1974, to review the declaration for the domestic transmission capacity service declaration (DTCS). The purpose of the review was to determine whether the DTCS declaration should be re-made, extended, revoked, varied or allowed to expire.
On 19 March 2009 the ACCC released a final report on the DTCS declaration inquiry. In the final report, the ACCC decided to vary the current declaration to exclude the capital-regional transmission routes and exchange service areas granted exemption in November 2008 as part of the ACCC's decision on Telstra's exemption applications. The ACCC also decided to extend the varied declaration for a period of five years.
The declaration commenced on 1 April 2009 and expires on 31 March 2014.
