Prime Minister Kevin Rudd has been asked to commit to at least three leaders' debates during the election campaign.
Mr Rudd will go head-to-head with Opposition Leader Tony Abbott on Tuesday in a nationally televised debate on health and hospitals.
Liberal Party federal director Brian Loughnane wants at least three more during the election campaign.
"It's (also) very important that Mr Rudd honours his commitment to have three debates during the election campaign," he told ABC Radio.
"There should be ample opportunity for people to draw the contrast."

The government and opposition have called on each other to release fully costed policy details during Tuesday's debate, but neither side is willing to do so.
The coalition's only health policy, so far, is for public hospitals to be run by local boards in NSW and QLD.
Labor has proposed a federal overhaul of hospital funding. Mr Loughnane defended Mr Abbott's decision to hold off on his policy plans.
"Tony Abbott and the coalition will be presenting realistic, direct plans that are going to have a real effect on people's lives well before the next election."
Health Minister Nicola Roxon said policies on preventative health and aged care were on hold until agreement from the states on the health reform package was met.
"We've made clear that there are more issues ... to be announced but we are in very heavy negotiations ... about the changes that have already been put forward," she told ABC Radio.
