Eddie Jones is to be reunited with eight of his World Cup Wallabies when he takes charge of a Barbarians invitation team in Cardiff - just five days after quitting as Australia coach.

And in his first public appearance since his resignation on Monday, Jones told reporters on Wednesday (Thursday AEDT) he believed his job as Australia coach would have been compromised had he stayed in the role.
