Kitty Chiller says the World Anti-Doping Agency may have to look beyond Russia's drug-addled track and field program before the Rio Olympics after reports of a new scandal.
The Australian Olympic team boss does not want the Russian track and field team to compete at Rio but speculated that doping may be spread across the country's other sports.
Her claims follow a New York Times report on Thursday which claimed dozens of Russian athletes who competed at the 2014 Sochi Winter Olympics, including at least 15 medal winners, were part of a state-run doping program.
The report is broadly consistent with revelations by an independent WADA commission last November of widespread state-sponsored doping in Russia, which led to a ban on the country competing in international athletics competitions.
"You have to wonder whether it is further than just track and field (in Russia)," Chiller said.
WADA also released new numbers out of Russia showing that testing by independent authorities has decreased by more than two-thirds in the past year.
Chiller said she was shocked by news that WADA has suspended Kenya's anti-doping agency after determining a new law passed there to combat doping was "a complete mess".
The final call on whether either Russia or Kenya's track team will be eligible for Rio will be made by governing body IAAF at a June 17 meeting.
Asked if either country had enough to time to clean up their programs, Chiller said: "It's a tough ask.
"We don't think the Russian track and field team should be at the Olympic Games.
"If it is proven that there's state-sponsored systemic doping in any country there is no place for that nation at an Olympics.
"We have to do everything in our power to ensure that we continue our hard stance on zero tolerance to anti-doping and protect the clean athletes at Rio to ensure a level playing field.
"If that means countries aren't there so be it."
According to WADA, the compliance review committee cited issues with Kenya's new legislation which it said was not in line with the WADA code.
"They need to display with evidence that there has been a definite shift in their culture and approach to how they view anti-doping," Chiller said of Kenya's anti-doping agency.
"Unless they can prove that I don't think there is a place for them at Rio."
