Opposition Leader Bill Shorten has seized on leaks from the government party room saying they show the Prime Minister is unfit to govern the country.

Tony Abbott stunned MPs when he told them he scheduled a visit to a cancer research centre in Melbourne on Tuesday so he could justify billing taxpayers for a Liberal Party fundraiser in the same city the night before.

Mr Shorten told reporters on Wednesday the Prime Minister should "never need an excuse to visit a public hospital in Australia".

But he said the division within the government was the real story and not the Prime Minister's travel schedule.
