Hanson, who won three Olympic medals from his four campaigns between 1996 and 2004, is a director of an international business called Athlete Assessments.
He describes himself as an “international coaching consultant” and has worked previously with the Queensland Reds and Australian sevens teams.
Sharpe, a former Wallabies captain and dual John Eales-medallist, remains connected to the game following his retirement in 2012 and has worked as a television commentator.
RA chief executive Raelene Castle says the panel “will offer significant expertise and experience from both within and outside the sport and from both an on and off-field perspective”.
“Having these three individuals leading the process will provide a well-rounded perspective on the Wallabies program and enable us to take forward any key learnings for delivery into the major tournament preparations of all of our national teams over the next four-year cycle.”
