Ricky Stuart toured with the Wallabies.If you played another sport at the highest level or professional level So Jarryd Hayne is NFL counts. A professional golfer counts. Damien cook's beach sprinting counts as it was at the highest level. The all blacks count. Ricky Stuart if he didn't play a test doesn't count. Google says this "Ricky Stuart had a brief stint in rugby union in the early 1980s, where he played for Easts (Eastern Suburbs) rugby union club in Sydney." Not a high enough level.
We will say that if you played professional Super Rugby etc the top professional circuits around the world it counts
I am sorry @Defence I am not going to provide a strict definition or it is going to lead to people making angles if that makes sense. Run with the spirit of the criteria and I will make decisions on fringe cases on a case by case basis.
