Former prime minister John Howard says he has no desire to take up an official international role in any government coalition leader Tony Abbott might form.

Campaigning in Perth on Thursday ahead of the September 7 poll, Mr Howard got an early start to his traditional morning walk alongside Deputy Opposition Leader Julie Bishop.

And as he kept up his usual brisk walking pace in King's Park, Mr Howard said he was also content with the current speed of the rest of his life.

"My time of doing things like that are long behind me - my time in public life ended in November 2007, and all I want to do is help get Tony elected," Mr Howard told Fairfax Radio.

"Then I shall return to writing my second book and doing the things I have been doing the last five years. I am very content with all that."

Mr Howard, who visited three WA seats on Wednesday, said he was detecting a clear mood for change.

"You can't be complacent, but the public polls look alright and there is a feeling - particularly here in the west - that this has been a very incompetent government," Mr Howard said.

"They are really, seriously contemplating a change."

And continuing his positive frame of my mind, the famous cricket tragic even considers the Australian team a chance in the return Ashes series due to start in November.

"Have faith in them," he said.

"... I think the Englishmen will find playing us out here in a few months time a lot harder than playing in England - the teams are a lot more evenly matched than the recent result."
