​The Western Australian Junior Olympiad (WAJO) is an annual competition open to any and all students upto year 9 as an accessible step into advanced maths competitions, ultimately acting as an excellent stepping stone towards entering the Australian Intermediate Mathematical Olympiad (AIMO).
​​​
​
​
WAJO is hosted online in the last week of Term 3, therefore it enables students from outside the Perth Metropolitan area to enter.
​
Every October (Term 4 Week 1 in 2025), the WAJO team component is held in person at the University of Western Australia (UWA) and in Bunbury (South West WA).
The Individual Competition runs online: Tuesday 23 September 2025
​
​To express interest in entering, please ask the head of maths at your school.
If there is no progress through your school, please contact: wajo-maths@uwa.edu.au
