Latest opinion polls show a further drop in support for Labor two weeks out from an election, with one indicating the Prime Minister may struggle to hold his own seat.
The Nielsen poll, published on Fairfax websites, shows Labor's primary vote has fallen two points to 35 per cent.
After preferences, that gives the Coalition a six-point lead - 53 per cent to 47 per cent.
If the results were replicated evenly across the country on election day, Labor would lose 10 seats.
The poll of 2,500 respondents has a margin of error of 2.6 per cent.
Meanwhile, a Newspoll published in The Australian newspaper, shows Prime Minister Kevin Rudd is behind the Coalition candidate, Bill Glasson, in his Brisbane seat of Griffith.
The poll, of 500 voters, shows Mr Rudd trails his opponent 52 per cent to 48 per cent on a two-party preferred basis. The margin of error of 4.4 per cent.
Another Newspoll of almost 1,400 voters in the Coalition's eight most marginal seats in Queensland shows the Coalition's primary vote has surged eight points to 54 per cent, while the ALP's slipped to 32 per cent.
It shows the Coalition has a commanding two party preferred lead of 60 per cent to Labor's 40 per cent.
Mr Rudd's personal support has also fallen to 39 per cent, with 49 per cent of voters across the marginal seats preferring Opposition Leader Tony Abbott.
On Friday Mr Rudd predicted he would make a comeback ahead of the election.
"I am old enough to remember what happened in a campaign 20 years ago, in 1993, where the then-Australian Labor PM Mr Keating entered the race as the underdog ... I believe we are heading in a similar direction here in this campaign," he said.
The Coalition though is continuing to face questions over its policy costings and last night former Labor prime minister Paul Keating criticised their decision not to release policy costings until later in the campaign.
Speaking at the campaign launch for Labor frontbencher Bill Shorten last night, Mr Keating, took aim at the Coalition, saying they had no vision for the future.
"No imagination, no bigness and no heart," he said.
"So this is what we're facing - a sort of flim-flam opposition. One without standards."
He described the Coalition as "mean people" who don't have a vision for the country.
The release of the poll results came on day 19 of the election campaign, which saw Mr Rudd campaign in western Sydney and the Opposition reject an economist's analysis that it is facing a $30 billion funding shortfall to meet election commitments.
The Coalition's campaign spokesman Mathias Cormann said: "there are some pretty fundamental errors in the calculation."
Mr Abbott announced $420 million in new policy measures including a plan to buy unseaworthy boats from Indonesian villagers, boost the number of Australian Federal Police working overseas and fund Indonesian search and rescue capabilities.
Mr Shorten and Mr Rudd have ridiculed the boat buyback plan, with Mr Shorten calling the scheme a "bounty scheme for dodgy boats".
Mr Rudd has outlined how a re-elected government would reduce GST reporting requirements for small businesses.
He said businesses with a turnover of less than $20 million a year would lodge one BAS a year, instead of four.
