2019 Australian maths modelling challenge winners

Media release 4 minute read

Australia’s two top entries in this year’s International Mathematical Modeling Challenge (IM2C) have been announced.

29 May 2019: Teams from Brisbane Boys College and Canberra’s Lyneham High School have been selected as Australia’s two top entries in this year’s International Mathematical Modeling Challenge (IM2C), eclipsing 140 other submissions.

The teams each received a ‘meritorious achievement’ award from the Australian judging panel and will progress to the international judging round for 2019. The international results will be known in July.

Coordinated in Australia by the Australian Council for Educational Research (ACER), the IM2C sees students use their research, mathematical and creative abilities to develop a mathematical model to address a real world problem. This year, teams were asked to use mathematical modelling to determine what might be a sustainable population for the Earth under current conditions, and to model a possible future sustainable global population based on projected changes to policy and environment.

IM2C in Australia saw continued growth in 2019. A total of 142 teams from 49 schools in the ACT, NSW, Queensland, Victoria and Western Australia submitted reports within the competition period.

The judges identified 22 teams as ‘national finalists’ that had produced reports strong enough for very close consideration and, from these, three team reports were given awards:


  • Brisbane Boys College, Toowong: James English, Ethan Waugh, Xavier Catford and Ometh Rajapakse (Year 12), with team advisor Chicri Maksoud
  • Lyneham High School, Canberra: Khubaib Qureshi, Emily Brown, Sreeya Das and Junwei Bai (Year 10), with team advisor Bhavya Bhalla


  • Perth Modern School, Perth: Avalon Shaw, Talola John, Tina Soodi Shoar and Aryan Gupta (Year 11), with team advisor Glen McClelland.

ACER’s Ross Turner, IM2C Australia Director, said, “The two top teams both included students who were national finalists in 2018, suggesting that experience and practice in using mathematical modelling helps teams to improve their understanding and work. Their reports are now in the hands of the international judging panel.”

“Congratulations to everyone involved for taking on this challenging competition to solve real world problems.”
