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).
Enjoy our beautiful coastal surroundings while you’re here!
The Australian Maths Trust is committed to ensuring that every student and young person who engages with the AMT is safe, respected and protected from physical, emotional, psychological or sexual harm. We strive to create a culture of child safety, underpinned by strong leadership, inclusive practices, and ongoing accountability.
