Australia's top Olympic doctor has warned the next fortnight will be "the real test" in bringing the threat coronavirus poses to the Tokyo Games under control, as the team begins drawing up contingency plans for training in "safe" areas.

In his first interview since the coronavirus outbreak began in December, the Australian team's medical director, David Hughes, said human-to-human transmission of the flu-like disease in Japan was a "far from ideal" situation.

Dr Hughes said that while coronavirus was a "significant challenge that we would rather not have", the team was proceeding on the basis the Games would go ahead as planned.

"All sports now will be looking at pre-Tokyo preparation and ensuring that they do their training in a place that doesn't have active transmission for the coronavirus," he said. "That in itself could become more difficult. We are seeing local transmission starting to occur in quite a few places."
