Kate Lundy will have to don British team kit while rowing on the London Games course after losing a bet with her British counterpart.
The wager with Hugh Robertson had been over which of the countries would claim the most medals at the London Olympics.
Although the games don't finish until Sunday, Lundy is already conceding. While Australia has collected five golds, Britain has 22.
Had Britain fallen short, Robertson promised to wear an Australian field hockey uniform and dribble a ball around Australia House, the country's official government residence in London.
Instead, Lundy will carry out her forfeit during the Aug. 29-Sept. 9 Paralympics.
