The Armed Forces are to provide up to 3,500 extra troops for security duty at the Games after a private firm admitted it could not supply enough guards.

Part of the problem is that Turnbull has his facts wrong.

For example, his claim that civil unions are "better than nothing" has been shown by the overseas experience to be false.
