A damaging split has intensified in the Coalition over energy policy as MPs rail against Malcolm Turnbull's signature National Energy Guarantee, prompting complaints about an "incredibly frustrating" level of leaking and disunity.

Former prime minister Tony Abbott set the stage for the outbreak with a speech calling for Australia to abandon the Paris climate agreement he signed up to as prime minister, while outspoken Nationals MP George Christensen joined Mr Abbott in threatening to cross the floor and vote against the NEG.

A so-called National Party blueprint calling for three new baseload power stations was also leaked to the media, prompting backbencher Damian Drum to warn his colleagues that enough was enough.

"I’m incredibly frustrated that people think that they can talk about what happens in the party room publicly," he told Fairfax Media. "What happened in the party room needs to stay in the party room."
