A South Australian Newspoll has given the Liberals just 14% of the primary vote, four weeks before the state election.
And in a Victoria Morgan poll, One Nation has topped both Labor and the Coalition on primary votes, with 26.5%, compared to 25.5% for Labor and 21.5% for the Coalition. Labor leads both One Nation and the Coalition after preferences in the poll.
A separate Victoria Resolve poll has One Nation at only 11%.
