John Coates admits the Australian Olympic Committee (AOC) must tread carefully in its anti-doping crackdown, but is adamant cyclist Matt White has served on his last Games team.

White is the obvious first casualty of the AOC's decision to make all Games athletes and officials sign a statutory declaration, saying they have never been involved in sports doping.

This new measure carries extra weight because swearing a false declaration is a criminal offence.

Coates, the AOC president, proposed the new measure in the wake of cycling's Lance Armstrong doping scandal.
