LNP candidate Bill Glasson has asked voters in ex-prime minister Kevin Rudd's Brisbane seat to not judge him based on the prime minister and Queensland's premier.
Instead, he wants them to judge him on own achievements.
Prime Minister Tony Abbott launched Dr Glasson's campaign for the seat of Griffith, vacated by Mr Rudd, on Saturday in lead up to the February 8 by-election.
An ophthalmologist and former president of the Australian Medical Association, he refused to say whether Mr Abbott or Premier Campbell Newman, who also joined the launch, would affect his changes of winning.
"This is not about the prime minister, it's not about (Labor leader) Bill Shorten, it's not about the premier, it's about Bill Glasson and his Labor counterpart," he told reporters.
"I want the people of Griffith to judge us; hold us up, Bill Glasson in one hand and the labor opponent in the other, and say who would you want to represent you for the next three years in federal parliament?"
He said his vast experience as a doctor, a small business owner and medical volunteer worker overseas and across Australia made him the better choice.
"In terms of life experience and in terms of leading major organisations over the past 20 years or so I think I come out in front," he said.
Mr Abbott said Dr Glasson was not an ambitious career politician.
"He's not going into the parliament to promote his career or to build his ego," he told the party faithful during the launch.
Dr Glasson did manage to effect a 5.5 per cent swing against the former prime minister at the general federal poll last year.
He said his priorities include addressing the cost of living, creating more jobs, child-care costs, more infrastructure and building safer communities.
