Former prime minister John Howard says there's no "thirst for change" in the Australian electorate ahead of the July poll.
Campaigning in the Adelaide Hills seat of Mayo on Tuesday, Mr Howard has also attacked Opposition Leader Bill Shorten, critical of his former union background.
He said the election would come down to a choice between Prime Minister Malcolm Turnbull, who understood business and the economy and Mr Shorten, who had indicated he would "govern like a trade union leader".
"To say that you're going to govern like a union leader is a very narrowing attitude," Mr Howard told reporters in Strathalbyn, south of Adelaide.
"I think that is bad for Australia.
"You want someone who is going to govern for everybody."
Mr Howard said he didn't believe Australians were angry with the coalition government.
"I've been to Queensland, I've been to the western suburbs of Sydney, and I don't find anger," he said.
"I think the campaign is taking a while to gather momentum because it's longer than usual.
"I don't find any thirst in the community to return to the chaos of the Rudd-Gillard-Rudd years."
Mr Howard said he believed there was an overwhelming case for returning the Turnbull government.
