Official International Mathematical Olympiad 2025 Website

Welcome to IMO 2025 Australia

The Australian Maths Trust, on behalf of the Australian mathematics community, is excited and honoured to host the 66th International Mathematical Olympiad on the Sunshine Coast, Queensland, Australia in 2025.

The IMO is the largest and most prestigious of all the international Olympiads, having grown from seven countries to over a hundred each year. IMO brings the brightest young minds from around the world and represents the culmination of many years of mathematical endeavour and hundreds of attempts at solving problems. Australia has participated since 1981 and has hosted only once before (Canberra, 1988).

The Sunshine Coast is the selected location. It is sunshine by name and sunny by nature with more than 100km of coastline where the rainforest meets the sea. You might even meet some of our beautiful native wildlife – which you may find in your backyard (just remember to keep a safe distance as they can be protective of their space).
