"I say to Australians, again — if you only really know the leader of a minor party, but you don't really know their candidates, and you don't really know their policies, don't vote for them. Australians won't want to end up next week with a result they didn't see coming."

Mr Turnbull was asked about the electoral prospects of South Australian independent senator Nick Xenophon, who has been tipped to pick up seats in the lower house, as well as at least three seats in the Senate.

The Prime Minister accused Senator Xenophon of taking a hostile approach to free trade agreements, suggesting he could hold a minority government to ransom over the issue.

"What about Nick Xenophon's demands? You talked about Senator Xenophon and his attitudes to free trade. The wine industry in SA is enjoying a renaissance of a kind it hasn't had in a very long time because of those big open markets, because of those free trade deal," Mr Turnbull said.

"Those who seek to stand against that, like Labor and many of the independents and the Greens, are putting Australia at an enormous disadvantage if they were ever to get to the position of being able to determine our future."

Senator Xenophon was quick to hit back at Mr Turnbull.

"Sadly, the PM has got it the wrong way around. There will be 'uncertainty and chaos' unless his government is forced to do the right thing by the steelworks at Whyalla and the 6000 jobs at stake, and nationally to tackle the tsunami of job losses expected as auto-making shuts down by the end of next year," Senator Xenophon said.

"We will make sure that SA is not forgotten in Canberra — and the best way to remind whoever forms government is to have a number of NXT representatives elected in both houses of Parliament."

Opposition Leader Bill Shorten also scoffed at the Prime Minister's pitch for stability, pointing to internal divisions in the Coalition over same–sex marriage.

"We know the Liberal Party is not united. Mr Turnbull says give me another chance, I will unite the nation. It's ironic because of the tensions in the Liberal Party but more importantly than that, the issues which affect working class and middle class people in Australia will not be solved by Mr Turnbull," Mr Shorten said.

"You cannot unite Australia whilst you are cutting school funding. You cannot unite Australia when your only policy for housing affordability is get rich parents. You cannot unite Australia when you won't take real action on climate change."
