Manage your team, Hewson tells PM

Former Liberal leader John Hewson says the prime minister needs to impose some discipline to end the government's embarrassing free-for-all on tackling housing affordability.

After a week of ministers openly arguing the case for allowing young people to tap into their superannuation to help build a home deposit, Dr Hewson says Prime Minister Malcolm Turnbull needs to put a management strategy in place.

"My solution, and it may not be transferable, is to give everybody a job, make them feel important in the policy development process. Kept them so damn busy they didn't have time to do all this stuff, and the ones you didn't like you sent them off overseas," he told Sky News on Sunday.
