Application Process Includes

The First Round is a two hour competition, usually held in February or March, at a number of locations across Australia. Participants work in teams of four on a range of language analysis problems. The teams are usually selected by their schools.

The competition is held at the local host university, with some schools also being able to act as host - there is also a  web-based option.

The top three teams for each region then go on to the National Round, which has the same format as the First Round. The National Round is usually held in late March, with results announced around Easter.

The winners of the National Round are offered the opportunity of representing Australia at the International Linguistics Olympiad(ILO), which is usually held in late July or early August.

All participants complete the same tasks, with achievements recognised at the Junior level (years 9-10) and the Senior level (years 11-12).
