THE Australian Competition and Consumer Commission's (ACCC) draft decision has proposed they won't be declaring a wholesale domestic roaming service.

The service, which would allow rivals telcos to roam using Telstra's network, was ruled against by the ACCC due to "insufficient evidence”.

Maranoa MP David Littleproud said he was disappointed to learn of the decision but wouldn't back down on improving mobile coverage and competition for the people of Maranoa.

"While I respect the umpire's decision, the fact is that what we've got isn't working and I'm committed to improving telecommunications for my communities,” Mr Littleproud said.

"The ACCC said in its draft decision it has insufficient evidence - with key information being commercial-in-confidence - that a declaration will improve the current state of competition overall.

"The people of Maranoa deserve to know how their provider will help them, their family and their business into the future, and this is now more important than ever with this Coalition Government's focus on decentralisation.”

Mr Littleproud said most in the Maranoa were Telstra customers and a solution to the problem was required.

The ACCC will make its final decision in mid-2017 and invites submissions on the draft decision until June 2, 2017.
