The AIO submission site is ready for schools to run the contest!

Teachers and Students: Please continue through to the online submission site, where:

  1. teachers may log in to register their schools and students;
  2. teachers may log in to start the contest clock (the school's three hour timer);
  3. students and teachers may log in to submit their solutions during the three hours of the contest.
Please contact us at aioquery@amt.edu.au if you have any difficulties with the site.

Students: Sample solutions from the 2003 competition in all of the supported AIO languages are provided below. You may also wish to take a look at the online training site, where you can practise past AIO problems and sharpen your skills!


The Australian Informatics Olympiad (AIO) is a computer programming competition that is held annually in early September. From 1998 until 2004 it was called the Australian Informatics Competition (AIC). In 2005 it was renamed the Australian Informatics Olympiad, with the AIC becoming a pencil-and-paper competition that you can read more about here.

Frequently Asked Questions

A list of questions and answers can be found on the AIO information page at the Australian Mathematics Trust.

If you have any queries on how to enter, you are welcome to phone the Trust at (02) 6201 5137. If you have technical questions about the competition, please write to aioquery@amt.edu.au.

Contest Rules

Each student should receive a printed copy of the contest rules [PDF]. Students and teachers should familiarise themselves with these before the contest.

Language Templates

In previous AIOs, we have seen many students who could solve the algorithmic part of tasks but would score no marks due to having little experience with file input and output. We will provide students with template code for each problem in each supported language. These templates will provide the skeleton of a program to perform the necessary I/O to read the input files and write to output files in the correct format. They will not solve the problem but may be used as a starting point by the student.

Students may download these templates when the competition begins by logging into the the competition site. Note that these templates are entirely optional. The student may wish to disregard the templates or modify them in any way they wish.

Sample Problems

The table below lists some sample problems from the 2003 competition, along with sample solutions in most of the supported programming languages. You may also wish to take a look at the online training site, where you can view problems from every past competition and submit your own solutions for on-the-spot judging! Please note that, although the training site only accepts C, C++ and Pascal solutions, other languages such as PHP, Python, Java and Visual Basic, Visual Basic .NET and C# are also allowed in the AIO.

ProblemSample Solutions Score
Culture C, C++, C#, Pascal, Java, PHP, Python, Visual Basic 100%
Stacking Numbers C, C++, C#, Pascal, Java, PHP, Python, Visual Basic 50% (correct but too slow)
Zig-Zag Cipher C, C++, C#, Pascal, Java, PHP, Python, Visual Basic 100%

You are of course encouraged to find a solution to Stacking Numbers that is fast enough to score full marks!

Past Results

Results of previous AIOs (or AICs as the competition was named until 2004) can be found on the AIO results page at the Australian Mathematics Trust.
