More than 100 mobile phone black spots have been identified across South Australia's mid-north and Yorke Peninsula by the local Regional Development Australia (RDA) board.

Chief executive Kelly-Anne Saffin said the black spots were in high tourist traffic areas like the Clare Valley, just two hours drive from Adelaide.

"It's very clear to us that one of the disadvantages we have is that our population bases are quite spread," she said.

She said the topography in areas like Sevenhill in Clare made it quite difficult to achieve mobile services.

"However, it's fundamental to us to have businesses, to grow businesses, to have emergency services and that level of requirement," Ms Saffin said.

The board will argue its case for Federal Government funding after compiling a list of black spots through consultation with local councils and communities.

The Government reaffirmed its pre-election commitment to allocate $100 million for a Mobile Black Spot program in 2014-15 and $30 million annually for the following three years.

It promises to commence a "competitive selection process" in the second half of the year once the design of the program was finalised and guidelines were released.
