Wales kept the momentum going in the second half with a third try, scored by scrum half Robert Lewis (Dragons), converted by Jones, for Wales to go 24 points clear.
The Aussies had to be content with a try by Andrew Barrett, converted by Quade Cooper, before the impressive Jones kicked a final penalty goal to seal a memorable win and make it a double over the tourists – who had never lost on Welsh soil before – after Tuesday’s 14-7 win by a Welsh Regional Select XV.
