At the leaders' debate tonight - to be held at the National Press Club - Malcolm Turnbull and Bill Shorten will face one hour of questions, and they are sure to be tough ones.
Seasoned journalists will be on the panel at the National Press Club.
Mr Shorten won the coin toss and elected to go second. Mr Turnbull will open the debate.
The leaders are sure to be asked about the economy and health policy - two issues that continue to dominate the election campaign.
Mr Turnbull will be questioned about the continued freeze on the medicare rebate, extended in the recent budget to 2020.
The Royal Australian College of General Practitioners has launched an emotional TV campaign saying the costs of a visit to the GP will increase.
The Australian Medial Association is also backing the campaign. It's new President Doctor Michael Gannon said today that he supported the ALP policy on the medicare freeze and he hoped the Coalition would change its stance.
The freeze means the rebate for a standard visit to a GP remains at $37.05. The freeze was introduced by the former Labor Government but continued under Coalition Prime Ministers Tony Abbott and then Malcolm Turnbull.
Tonight's debate is also likely to focus on policy costings.
Before the debate, Mr Turnbull said he was ready and described the decision of the Australian people as a "a choice between optimism and opportunity and growth."
Bill Shorten also said he was prepared.
"I am looking forward to this debate" he said.
"I am looking forward tonight to talking about Labor's positive plans."
The debate gets underway at 7.30 PM.
