The federal government on Tuesday confirmed a further $60 million would be made available for a third round of the program rather than in the recent budget.

The announcement of the extra funding was made by Prime Minister Malcolm Turnbull and National Party deputy leader Fiona Nash in the marginal electorate of Corangamite.

In addition, four locations where towers would be built to eliminate blackspots in Corangamite was announced.

The Coalition government is expected to make a similar announcement in Indi shortly.

Coalition candidates Sophie Mirabella and Marty Corboy have nominated the Beechworth-Wodonga Road as a priority.

Indi MP Cathy McGowan's priority locations are the Omeo Highway between Lake Hume and Eskdale, the King Valley including Cheshunt and Rose River and Kevington near Mansfield.

Ms McGowan called on the government to make more funding available for mobile blackspots before before parliament broke ahead of the election campaign.

“There needs to be a greater focus in providing coverage to farmers, small businesses in rural communities and emergency and bushfire-prone areas,” she said.

“Poor mobile phone reception remains the number one issue for Indi.

“As a local, I understand this issue and as an Independent with an effective plan, successfully lobbied to get improved mobile phone coverage in the North East.”

But Ms McGowan has come under fire from federal MPs including Darren Chester for taking credit for Coalition policies including blackspot funding.

The $60 million will take the government's commitment to fixing blackspots to $220 million since 2013.

Mr Corboy said he would be reinforcing his priority locations with Ms Nash in coming days.

"Country people should not be forced to travel long distances, stand on fence posts or climb onto their roof just to make a phone call," he said.

“It is why I highlighted the importance of additional towers for Indi with Fiona Nash on her visit to the electorate in April and again last week.”

The Indi electorate was one of the major winners in round one with 30 towers funded, but more than 40 locations still need upgrading.

Mrs Mirabella said: "This is wonderful news that the Prime Minister has listened to his team in rural and regional Australia.

"I'm proud to have been part of an Opposition that developed this policy.

"There is more work to be done and soon I will be showing the minister for communications, Mitch Fifield, first hand the challenges we have with mobile phone blackspots in Indi."
