The coalition might not reveal the cost of all its policies until the last week of the election campaign, but Opposition Leader Tony Abbott says it won't be as late as the last day.
Mr Abbott says every policy will be funded and costed so Australians are in no doubt of the coalition's economic plans when they go to the polling booths.
"And we intend to keep putting out policies right up into the last week of the election campaign," Mr Abbott told ABC's 7.30 program on Thursday.
"So when all our policies are out we will be able to tell you exactly how much we are going to spend, exactly how much we are going to save and exactly what the overall budget bottom line will be and how much better it will be than under the Labor Party."
Mr Abbott said the coalition would not release them at the last minute, like Labor did before the elections in 2010 and 2007.
He again rejected as lies, Labor's claim that he would increase the GST.
Mr Abbott, who coughed throughout the interview, said the coalition had more to say on health over the next three-and-a-half weeks.
He also said the coalition did not like Labor's three new taxes - on tobacco, the bank levy and changes to the fringe benefits tax on cars - but they might have to keep the first two.
"We possibly might have to," he said.
But he would not go ahead with the fringe benefits tax on cars because it was a "disaster" for the industry.
Mr Abbott reiterated that there was a challenge ahead to manage the budget and find savings but said there would be no overall increase in the tax burden.
He said there was an enormous amount of waste in the system but the coalition had a record of surpluses.
