Former Australian finance minister John Fahey was re-elected to a second three-year term as president of the World Anti-Doping Agency (WADA) on Sunday.
Fahey, 65, who took over from Canadian Dick Pound in 2007, was unopposed in a vote conducted at the agency's foundation board meeting.
In a statement Fahey said the fight against doping had continued to make significant strides over the past three years.
"High-profile doping cases and investigations underscore the fact that no sport and no country are immune to the threat of doping, as well as the critical need for strong sport-government collaborative efforts in confronting doping," he said.
Vice-president Arne Ljungqvist, who heads the International Olympic Committee's medical commission, was also confirmed for a second three-year term.
