In four weeks' time, Moyes will be preparing to take charge of his United team in Barclays Premier League combat for the first time at Swansea.
That opening-day trip to Swansea will begin the acid test of whether Moyes can fulfil the faith Sir Alex Ferguson showed in him. And had Ferdinand been given the responsibility, he would have reached exactly the same conclusion.
"We've got a manager who's very enthusiastic," Ferdinand told Sydney's Daily Telegraph. "He's young and has got the desire and appetite to be successful.
"After the manager we had, that was very much needed and he's someone I would have chosen if I was in a position to.
"He's not someone who is looking to come in for three or four years - he'd love to replicate what the manager has done.
"There were people who'd have come into the job, who maybe wouldn't have wanted to be here for that amount of time.
"I'm sure the new manager sees this as a job for the long term."
