The News Corporation boss attacked Australia's 1.7 million public sector workers comparing them to "phoney welfare scroungers" while he lauded the Coalition's victory in Saturday's federal election.

The media mogul, who is a US citizen, took to social media site Twitter on Saturday evening to launch his attack on the public sector and to predict that "other nations" would follow Australia into more conservative politics.

"Aust election public sick of public sector workers and phony [sic] welfare scroungers sucking life out of economy," Mr Murdoch wrote.

"Others nations to follow in time."

Mr Murdoch's Australian newspaper empire, including the mass circulation The Daily Telegraph, the Herald Sun and the loss-making title The Australian, attracted criticism from the Labor Party during the lead-up to the election for its campaign for a Coalition win.

A key campaign pledge of incoming prime minister Tony Abbott has been to axe 12,000 public service jobs.

Mr Abbott has also increased the efficiency dividend on public service departments and promised a "commission of audit" that will look at where more spending can be reduced.

After his initial swipe at public servants and other public sector workers, Mr Murdoch returned to Twitter in the early hours of Sunday morning to accuse public sector workers of taking many more sick days than their private sector counterparts.

"Small item: apart from higher pay, public workers in Australia take many more sick days than those in hard working private sector!" Mr Murdoch tweeted.
