Radheya (15) played in the National Scrabble Championships in Melbourne, while younger brother Rahul (13) swam in the Indian Ocean All-Stars Challenge in Perth.
Rahul won four gold, two silver and two bronze medals as well as the 13-year-old group prize for Outstanding Male Swimmer.
He said he enjoyed the competitive nature of the day.
�I was pretty excited to represent Australia competing against the Asia team,� he said.
�Before the event we had a get-to-know-you session with some coaches and one with my own coach, Travis Nederpelt.�
Radheya won the Highest National Ratings Gain for Youth and finished second overall in the National Scrabble Championships.
�It was a really fun experience because I have never travelled for scrabble before and I think it provided me an insight into what happens in those kinds of tournaments,� he said.
�I was very nervous… (but) I�m quite happy with the results I got.�
