Prime Minister Tony Abbott says he will "absolutely" lead the government to the next election and has described the strong performances of potential leadership rivals Julie Bishop and Malcolm Turnbull as the result of their "good captain".

Visiting Colac in Victoria on Friday, Mr Abbott was peppered with questions about his leadership, the future of his chief of staff Peta Credlin - and whether he would stand aside for Ms Bishop or Mr Turnbull.

Mr Abbott responded by praising his "strong colleagues" and "strong team" but said they benefited from his leadership.

"One of the reasons why so many members of the team are able to perform so well is because they have got a very good captain," he told reporters.
