SYDNEY - Prime Minister Kevin Rudd vowed to fight until "the last vote is cast" in a rousing speech declaring himself the "comeback kid for Australia" Sunday, one week out from national polls.
Rudd urged the party faithful not to give up hope, despite opinion polls showing the Tony Abbott-led conservatives as clear favourites to win the September 7 election.
"To those who say that Mr Abbott has already won this election, I say this - never ever, ever underestimate the fighting spirit of the Australian Labor Party," Rudd told the party's major campaign rally in Brisbane.
"I have been in tougher spots before and come back from behind.
"As one young kid said to me the other day - 'Kevin, we want you to be the comeback kid for Australia'."
Rudd said he would "fight this election until the last vote is cast next Saturday night".
"I believe we can prevail and I believe in the end we will prevail," he said.
Rudd took aim at Abbott's "priorities, judgement and temperament" in his speech, after the opposition leader described the conflict in Syria as "baddies versus baddies" in a television interview Sunday.
The Rudd camp seized on the remarks, made as Australia prepares to assume the rotating presidency of the UN Security Council, as evidence Abbott was not ready for the international stage.
"Can you imagine him at the G20? 'Barack, it's baddies versus baddies'," said Labor Senator Penny Wong.
