"One of things in political life, and like life in general, is that it should never be a case of would of, could of, should of," he told the Seven Network on Saturday.
"You work with what you have got."
Mr Rudd conceded that Labor had got "stacks of things wrong" in government.
"Name me one government over the years which hasn't got things wrong," he said.

"So let's not just pretend that internal political challenges exist on one side of politics."
