One Electric Day first launched on the mainland in 2013, and attracts crowds of more than 10,000 people.

This year's lineup includes massive names such as John Farnham, Jon Stevens, Vanessa Amorosi, The Black Sorrows, and Southern Sons.

"There is always such a buzz around the Melbourne show," he said.

"This is such an exciting opportunity for us to share some of Australia's best talent with audiences around Australia, and we are stoked to be launching the national One Electric Day series with John Farnham."

"We expect audiences in Launceston, Sydney, Brisbane and the Barossa will embrace One Electric Day the same way Victorian music-lovers have and help us make this an annual event in their towns," Mr McDonald said.

The festival is organised by the promoters of the well-known Red Hot Summer Tour.
