Wayne Swan will lose his Brisbane seat of Lilley at the 2013 federal election, unless Kevin Rudd is reinstated as Labor leader.
A ReachTel phone poll of 693 residents on Friday night found that 37.4 per cent of voters would put Mr Swan as their first preference, behind the LNP’s Rod McGarvie on 45.2 per cent.
Mr McGarvie leads 54 per cent to Mr Swan’s 46 per cent two-party preferred.
However, that figure would be directly flipped should Kevin Rudd return to the prime ministership.
The ReachTel automated survey asked participants who they would vote for in that scenario.
A total of 47.9 per cent listed Mr Swan as their first preference over Mr McGarvie on 40.1 per cent.
Two party-preferred, the Federal Treasurer would be ahead 54 to 46 per cent.
Asked who they thought would make the better prime minister, participants responded 53 per cent for Tony Abbott over Julia Gillard, on 47 per cent.
Ms Gillard also attracted a 51.9 per cent "unfavourable" opinion from participants, with 29.5 per cent "favourable".
Mr Abbott ranked 46.4 percent "unfavourable" and 34.8 per cent "favourable".
