15th out of the 96 participating countries, ahead of Great Britain...
The Australian team gained major ground at the 51st International Mathematical Olympiad (IMO) in Astana, Kazakhstan, July 2010. Australia came 15th out of the 96 participating countries from 23rd position in 2009. The team won a Gold Medal, three Silver Medals and a Bronze Medal.
Australia had higher scores for the first time than major countries such as Iran, Romania and Bulgaria, each of which had been the top-ranked country at IMO at some time since 1996. Australia also defeated Great Britain, which had defeated Australia just a week before in the annual Mathematics Ashes.
