Six of Australia’s top mathematics students have participated in the 64th annual International Mathematical Olympiad (IMO) in Japan.   The team was awarded five medals and an honourable mention, helping Australia rank 23rd out of the 112 countries that took part in this year’s competition.

Australia’s sustained excellence on this international stage continues with Australian teams placing in the top 25 of all participating countries in 8 out of the last 10 contests.

The students from schools in NSW and Victoria, ranging from Year 9 to Year 12, participated in the IMO from 2-13 July. They competed against more than 620 of the brightest young mathematicians from across the world.

“It is so exciting to see our IMO team perform so well this year.  The team has worked exceptionally hard this year and it’s wonderful to see all their efforts rewarded – I congratulate them all on their outstanding achievements.  I am also very grateful to our supporting staff, led by Dr Angelo Di Pasquale, who have assisted the team in their preparations.  Our continued strong performances at the IMO are inspiring particularly as we work towards hosting the IMO in Australia in 2025,” said Nathan Ford, CEO, Australian Maths Trust (AMT).

Australia’s top performer in 2023, Zian Shang, scored a total of 35 points, ranking him 26th in the world and earning him a Gold Medal.

Australia’s other medals awarded were Silver Medals for William Cheah and Christopher Tran, and Bronze Medals for Sizhe Pan and Cloris Xu. An Honourable Mention went to Iris Xu – this award goes to those students that solve a complete problem on the paper.

The selected students have spent a year participating in exams and intensive training within the AMT’s Performance and Pathways program.
