A Galaxy Poll, conducted for News Ltd in Australia, says the Coalition is ahead with 54% compared to Labor's 46%, on a two-party preferred basis.
AAP reports that it showed one in five voters believes prime minister Julia Gillard was completely open and honest over her role in an Australian Workers Union scandal in the early 1990s, but a majority said it will not change their vote at the next election.
Among Coalition voters, 81% believe Ms Gillard should explain herself over the affair with a statement to Parliament, but only 36% of Labor voters think that is necessary.
AAP reports the poll surveyed more than 1000 people across Australia on Thursday and Friday nights and said if elections were held now, Tony Abbott would be elected prime minister.
