"I have been an advocate, supporter and significant funder of amateur and professional sport all of my life and the opportunity to make an impact with WinSport has been personally rewarding," O'Neill said in the statement.

"I have every confidence that Stephen will ensure our shared vision of becoming a one-stop shop for elite athletes is realized."
