The Tasmanian senator said no one could deny the difficult position facing the Liberals, who have sunk in the polls after losing dozens of seats across two successive elections, but expressed confidence they would form government again.
"This challenge is not insurmountable. We have a history and we should be proud of it," Duniam told the Senate on Wednesday afternoon. "My party can give Australians what they need. Not by pretending to be someone else or seeking to appease certain actors, but by returning to our roots, by backing [our values] in with conviction … and explaining why it is better than the alternative."
Coalition MPs have diverged over how to approach One Nation's rising popularity. Some have urged the party to take up the fight, in particular MP Andrew Hastie, described by Duniam as his Canberra family. Others have talked up preference deals or forming government with Pauline Hanson's party.
Duniam said the Liberals needed to put forward their plan and make the case to voters. "We should never wave the white flag," he said.
"My party has been around for decades. It isn't populist. It isn't flash in the pan. It is here to stay. And sure, we may have spent some time in the wilderness, but we have our bearings now and I know we will be able to get back over there into government."
