The Barbarians will be coached by 1987 RWC winner Sir John Kirwan in their Killik Cup meeting with Australia at Twickenham on November 1.
Kirwan is also going to be in charge when the team takes on Leicester Tigers at Welford Road on the following Tuesday, the Baa-baas revealed.
The 49-year-old, who scored 35 tries for New Zealand in his playing career, went on to coach Italy and Japan before taking over at the Blues.
“In my view, it’s the first Test of their tour. That is what they will be expecting and that is what we want to deliver,” coach Kirwan said of Australia.
“It’s a privilege and a huge honour to be involved with the Barbarians again.
“Every year the Barbarians are put under pressure, but it’s still a huge honour to play and they still compete with the very best.”
