Dad David played two tests for Australia in the early 90s and has been based in Ireland since his appointment as Performance Director of the IRFU in 2014, with local media describing him as "one of the most powerful men" in Irish rugby.
He succeeded Peter Sloane as the Blues head coach in 2006 after being appointed technical director and high performance manager a year earlier.
He was replaced by Pat Lam in 2009 after opting out of his contract a year early for family reasons.
"I feel like I have been on the road for seven years now in this competition and dragging my family around," he said in May 2008.
"We felt that it was the best time to come back to Australia for the sake of my children. We are getting into their high school years and we wanted to settle down a bit."
