The South Australian premier, Jay Weatherill, unloads on the federal energy minister, Josh Frydenberg, at a media conference in Adelaide.

Weatherhill hit back claiming the Coalition was the ‘most anti-South Australian commonwealth government in living history’ and that it was ‘galling’ to listen to Frydenberg’s claims
