From the classroom to the world stage!

The Australian Science Olympiads (ASO) is a staged science enrichment program for highly motivated students in Australian high schools. The program covers four separate disciplines: Biology, Chemistry, Earth and Environmental Science, and Physics.

The program allows schools to test student abilities against the national cohort; provides opportunities for teachers to challenge and extend their very best students; and allows students to build their skills, experience, knowledge and connections.

The program consists of three stages:

  1. Competing in one or more Australian Science Olympiad Exam; offered in biology, chemistry, Earth and environmental science, and physics.
  2. Being invited to attend the Australian Science Olympiad Summer School in one of the four disciplines.
  3. Being selected to represent Australia at an International Science Olympiad.

While only a select few will go on to make the international teams, participation in the ASO Exam and Summer School is a prestigious and valuable experience for schools and students alike.

Australian Science Innovations have been coordinating the selection and support of the Australian teams for over thirty-five years, with staff who go above and beyond for the program. Our dedicated participants are supported during every step of this exhilarating journey. We are proud of the quality of the program and the results achieved.

Take a look at our other great programs, the Junior Science Olympiad program for Year 7 to 10 students, or the Big Science Competition.

Australian Science Olympiads Summer School

Following the completion of the exams, high achieving students may be selected and offered a place at our residential camp, ASO Summer School, held at the Australian National University in January. This part of the program is by invitation-only.

Each year, we invite twenty-four of the top performing eligible students from each of the Australian Science Olympiad Exams (Biology, Chemistry, Earth and Environmental Science, and Physics) to the Australian National University for two-weeks of accelerated hands-on learning. Students are selected to participate in one discipline only.

ASO Summer School is a chance for students to further extend themselves in their discipline, connect with subject experts, and develop new friendships with like-minded students from across the country.

The students grow so much as individuals, but also take their new-found confidence, leadership and team-building skills and expanded science-repertoire back to the benefit of their schools and peers.

All 96 students who attend the ASO Summer School are deemed to have the potential, and may be selected, to represent Australia at the International Science Olympiads.

The ASO Summer School has been a staple of the Australian Science Olympiads experience for over thirty years!

ASO Summer School FAQS

Early in the new year, 96 students travel to Canberra for over 2 weeks of intense science programs at the Australian National University. Students are selected to participate in one of the disciplines only, and will actually complete one university-level subject of either Biology, Chemistry, Earth and Environmental Science, or Physics.

Students will be exposed to science like never before and will be challenged to learn, adapt and extend themselves in hands-on practicals, challenging theory examinations and in-the-field research. It is an opportunity to use world-class science facilities and meet world-renowned experts in their fields.

This is a highly structured and intensive residential school. The students are fortunate to be guided by program directors and deputy directors, dedicated to sharing their skills, knowledge, and experience. They are mentored and supported by program staff who have experienced ASO Summer School themselves. A team of support staff are available to ensure their experience is safe, fulfilling and enjoyable.

Being selected to attend ASO Summer School is not only a great opportunity to delve further into science, but the students undertake examinations and testing whilst here to be selected to represent Australia at the International Science Olympiads.

Staying on-campus in Australian National University accommodation is also an amazing experience, and it’s a great opportunity to gain first-hand insight into ‘university life’. A highlight is meeting other like-minded individuals who share a passion for science.

ASO Summer School is a once-in-a-lifetime experience, available for selected high achieving students chosen after sitting the ASO Exams.

To be eligible to accept the Australian Science Olympiads Summer School invitation, students must:

  • Have sat one of the discipline specific Australian Science Olympiad Exams
  • Hold current Australian citizenship at the time a Summer School offer is made
  • Reside in Australia
  • Students must be 15 years or older at the time Summer School commences

Entry into the ASO Summer School program is by invitation only. Successful students will be contacted via phone and email to offer them a place.

Whilst you cannot apply directly to attend ASO Summer School, you can contact your science teacher or school admin about participating in the ASO Exam at your school.

In 2024, the cost was $3,000, which covers all travel, meals, accommodation, tutoring and equipment. Financial assistance is available where students can show financial need.

International Science Olympiads

A chance to represent Australia at the International Science Olympiads!

Following the intense learning sessions and further exams at the ASO Summer School, the teams are selected to represent Australia at one of the International Science Olympiads. Four students are selected in Biology, Chemistry and Earth and Environmental Science. Five are selected in Physics.

Olympiad medal wins provide recognition for the Australian schools and teachers leading the way in shaping our scientists of the future.

Making an Australian Science Olympiad Team involves:

  • A further residential training program – in April for Biology, Chemistry and Physics, and in July for Earth and Environmental Science.
  • For physics only, eight students are selected to attend the Asian Physics Olympiad in May.
  • An official Australian Olympiad Teams Announcement at Parliament House in June – affectionately known as the Blazer Ceremony, students receive their team uniform with the official Australian Coat of Arms. Immediate family, teachers and principals are invited to attend.
  • Travel to the host country in July or August to compete on an international stage, and to engage in exciting cultural activities.

This competition encourages students to develop their talents and provides an environment for students to connect with people from unique backgrounds from across the world and experience different cultures. They have worked so hard to be selected and to prepare for the international competition, their achievements thus far are inspiring. The many medals and awards that our teams have won are well deserved, as you can see on our Honour Roll!
