Workplace reform, motor industry support and a debate about the depth of the Government's deficit are the focus as Opposition Leader Tony Abbott joins Jon Faine.

Opposition Leader Tony Abbott says the Coalition is proposing changes to when strike action can be taken, among other workplace reforms.

"If we are going to be the highest paid workers in the world, or amongst the highest paid workers in the world, we've got to be amongst the most productive workers in the world," says Tony Abbott.

Tony Abbott cited the CFMEU blockade of the Grocon site in the Melbourne CBD as an example of what his party is targeting.

"We want to see the rule of law returned to our workplaces," says Tony Abbott.

He says a Coalition government would continue generous assistance to the motor vehicle industry as long as manufacturers demonstrated where they would reduce costs.

"If you are a first world economy you should be capable of making cars," says Tony Abbott.

Tony Abbott says the Government's Better Schools program is expensive and could land the government in financial trouble.

The Opposition Leader rejected the assertion that the education outcomes from the Gonski reforms justify the creation of a 'managable' deficit.

"These 'tiny, manageable, irrelevent' deficits can bring countries into terrible, terrible trouble, just look at what's happening in Europe," says Tony Abbott.
