Dumped prime minister Tony Abbott said governments will struggle to make difficult reform decisions and under the "febrile" politics which has led to party-room coups.
Mr Abbott, who was toppled by Malcolm Turnbull almost two weeks ago, questioned how governments could make difficult decisions when leaders are subject to "death by opinion poll".
"Obviously I know, having been a practitioner of politics in this country, that the top job has never been less secure," he told News Corp Australia.
Despite his promise of "no wrecking, no undermining and no sniping" after losing, Mr Abbott appeared to take a little dig at his side of politics.

"I never thought having watched the Labor Party implode that the Coalition would want to venture down the same path," he said.
He also suggested that nothing, apart from the Liberal Party leadership, had changed.
"In a policy sense, there is very little departure," he said.
"Border protection policy the same, national security policy the same, economic policy the same, even same-sex marriage policy the same, and climate change policy the same. In fact, the rhetoric is the same."
Mr Abbott said he would not make a decision about his future before Christmas, but believed he was far too young to stop working.
