Opposition leader Sussan Ley has announced the Liberal party will ditch net zero and repeal Labor's 2030 emissions reduction target - all in a bid for the Opposition to "put affordable energy first".

But does the policy behind the politics stack up? And is this an "overwhelming victory" for Liberal conservatives - and for the Nationals?

Michelle Grattan, Chief Political Correspondent for The Conversation joins Patricia Karvelas and Mel Clarke on The Party Room to unpack it all.
