Scott Morrison has indicated he would not deal with independents on policy in the event of a hung parliament after the election.
Speaking with residents at a retirement village in the Adelaide-based marginal seat of Boothby on Wednesday, the prime minister said he would not look to work with independents.
"I'm not going to do a deal on policy with the independents," he said.
"A vote for independents is a vote for Labor."
Mr Morrison also stressed he was seeking to form a majority government and warned against a minority parliament.
'I would say to people thinking about independents: one of our strengths has been majority government," he said.
While later speaking to reporters, the prime minister denied he was avoiding campaigning in key electorates where prominent independents are challenging moderate Liberals.
Prominent Liberals such as Josh Frydenberg in Kooyong and Dave Sharma in Wentworth are facing a surge in electorate support for independents.
"I will go where I believe it is best for my campaign for me to go, I'll flag where I go on the day," Mr Morrison said.
"I'm not going to be telecasting where I'm going each day, that's not something we do in campaigns."
It comes after a new Morgan poll released earlier this week found support for independents has risen by 1.5 points to 9.5 per cent.
Mr Frydenberg said he did not take his seat for granted and admitted the battle for Kooyong was a tight contest.
"(Independents) don't have any detailed policies that they're putting forward, and they're not prepared to tell the community how they will vote in the event of a hung parliament," he told ABC TV on Wednesday.
"I'm up against the so-called independent who's a former member of the Labor Party."
The prime minister will spend all of Wednesday in Boothby, which the Liberals hold by 1.4 per cent.
Following his visit to the retirement village, Mr Morrison will speak at a Liberal Party rally, alongside other South Australian candidates.
The prime minster also denied suggestions he was avoiding campaigning alongside Alan Tudge in his Melbourne seat of Aston.
Mr Tudge stood aside from his role as education minister in the wake of allegations he was emotionally and physically abusive to his staffer who he was having a consensual affair with.
The prime minister said Mr Tudge, who has denied the allegations, was always welcome back in the cabinet after the election should he wish to return to the frontbench.
"(Tudge) doesn't need my help (in Aston). He's done a fantastic job in Aston and he enjoys strong support," Mr Morrison said.
