The federal Member for Grey, Rowan Ramsey, says action is being taken to improve outback communications.

Stranded travellers in William Creek this week have reignited concern about a lack of mobile phone coverage and unreliable landlines.

Mr Ramsey said the Federal Government had committed $100 million to new mobile phone towers around Australia but it would not solve the problem.

He is also looking at whether Australia's National Broadband Network (NBN) satellites could be used for remote mobile phone use, while lobbying for other changes.

"I absolutely agree landline arrangements there at the moment are less than they should be and I've had a number of discussions with the Minister and the Parliamentary Secretary Paul Fletcher about the situation," he said.

"Absolutely I acknowledge it's an issue and it's not just William Creek - a lot of the outback properties run on these radio phone networks.

"There are a number of other possibilities of using the new NBN satellites for backhaul capacity to establish new and much cheaper mobile phone platforms."
