Welcome to the home of the Australian Invitational Informatics Olympiad!
The AIIO was held for the first time in 2006, and is now held every February. Entry is by invitation only, and the final results (as well as the FARIO results in March) are used to select the participants for the Informatics Selection School in April and the Australian EGOI team. At the end of the April school, a final four are selected to become the Australian team for the International Olympiad in Informatics.
