Australian Federal Election Aug 28 Recap:

Kevin Rudd and Tony Abbott are set to face each other again for a third debate at the Rooty Hill RSL Club in Sydney on Wednesday night, Aug 28.

Meanwhile, shadow treasurer Joe Hockey and treasurer Chris Bowen debate on Wednesday noon at the National Press Club in Canberra.

In a live update report from News Corp's Chris Bartlett, Mr Hockey claimed that erasing carbon tax will save $5.6bn over four years. For the Wednesday noon debate, he will release the interim costings of the Coalition's election promises, costing for parental scheme which will contribute to budget bottom line of up to $1.1 billion. The coalition's parental scheme has the lowest estimate budget cost at $3.3bn once other savings scheme is scrapped along with Labor's other budget scheme and lower welfare payments taken into consideration.

Mr Hockey will also promise not to cut health or education if the Coalition is elected, as reported by The Australian Financial Review. However, AFR also reported that the Coalition will only be able to save $5.6bn over four years because the party is also planning to scrap business and energy market compensation.

The coalition will detail the proposed 1.5 per cent company tax levy that it claimed will raise $4.4 billion until it reach the estimated funding of $9.8 billion - all targeted to happen in the first two years if coalition is elected.

As for Mr Rudd's $300bn rail plan, the Coalition topped it with its plan of new rail line linking Brisbane and Melbourne, according to Nationals leader Warren Truss. The coalition targets to begin construction of this $4.7bn project by 2016, if it gets elected.

Meanwhile, on the campaign trail, Mr Rudd courts construction workers in Griffith and Team Abbott goes to Hobart to announce $16 million for cadburry chocolate factory as reported by Gemma Jones and Lanai Scarr.

As for the recent report that Griffith is already leaving him, Mr Rudd said he is not worried and he is more concerned that if Mr Abbott wins, he will employ huge cuts that can dump Australia into major recession.

"I am not worried about what happens to me in this election, I am worried about kids who need to get a job," Mr Rudd said.

It seemed like that Mr Rudd had won the workers' hearts with his surprise visit to the construction site.

Henry Corvy, 60, a construction worker, said that he most likely will vote for Mr Rudd.

"There's nobody else is there? I wouldn't vote for the coalition," Mr Corvy said.

"We were just told it would be about Labor and voting," said surprised Darren Gersekowski, 37, another construction worker.

After his chit-chat with the workers, Mr Rudd goes to the Queensland teacher's Union office to give a short speech. He broke the ice by confessing to the teachers that he had wrote his name on a desk when he was still in the primary school.

"My name is still carved in a desk. Sorry about that," Mr Rudd said.

As the two candidates and rival parties work hard campaigning for the upcoming election, they were all being criticised for the lack of plans for the mental health policies.

Professor Allan Fels said that half the Australians are suffering mental health difficulties but the politicians seemed to be blind about the problem.

"I want to know why mental health is not a central issue in this election. Why have our political parties not been more forthcoming with their mental health policies. Our political leaders talk about building "a stronger Australia", about "a new way" forward. Well, there is no better place to start than our mental health and wellbeing," Mr Fels said.

The Mental Health Council of Australia had called for the politicians too.

"Despite there being almost three million registered voters who will experience a mental illness this year, the ALP and the Coalition are yet to release any significant mental health policy," according to MHCA chief Frank Quinlan.
