Swimmer Gerhard Zandberg on Monday told Eyewitness News Sport that he is hoping his Swimming South Africa appeal hearing will be a catalyst for change in swimming.
Zandberg was served with a R5,000 fine and ordered to do community service after switching rooms at the recent World Championships without consent.
He lodged an appeal against the sanction on his return to South Africa.
Zandberg says his roommate Cameron van der Burgh was sick and that his plea to move went unanswered.
The swimmer eventually changed rooms, at his own expense, before being disciplined in Barcelona just hours before his semi-final race in the 50 metres backstroke.
