Supermarket giant Coles is selling its fuel and convenience store operation for $300 million.
The 710 Coles Express sites are being acquired by Viva Energy, which already supplies fuel to Coles.
"Viva is well-placed to make the most of opportunities to grow the Express business into the future, while we will strengthen our focus on our ... supermarket and liquor businesses," Coles chief executive Steven Cain said on Wednesday.
