Attention, high school students! Meet world-renowned scientists. Explore cutting-edge research facilities. Build your STEM skills through hands-on workshops and activities, while forging new friendships across the world.
If you’re excited about STEM and in Years 11 or 12 in 2028, you should apply! Applications will open in early 2028.
Thank you for giving me this opportunity to attend ISS and live the best two weeks of my life!
In July 2025, 90 science students from across Australia and around the world gathered at the University of Sydney for ISS2025, the 44th Professor Harry Messel International Science School.
The ISS is almost 70 years old, and to this day it remains a unique international STEM extension program that gathers some of the worlds most talented young minds in Sydney for a program of inspiring, exciting science.
And best of all, it’s entirely free. All transport, accommodation, meals, science program and the events. Everything is provided by the University of Sydney’s Physics Foundation and our generous partners and supporters across Australia and overseas.
The next ISS will be held in July 2028, so if you'll be in Years 11 or 12 in 2028, start planning now to apply for our next ISS. Applications will open in early 2028, so watch this space to see when the application form goes live!
Thank you immensely for making this happen – the friendships and memories will last a lifetime.
We’re hard at work planning for the next International Science School in mid-2028. Here’s a taste of what’s in store.
Our lecture series features world-leading researchers from across STEM disciplines around Australia and across the globe. During the 60+ years of the ISS, we have welcomed top theorists and experimentalists, entrepreneurs and Nobel prize-winners, up-and-coming researchers and great scientific leaders – all with an inspiring story to tell. You can watch many past lectures on the ISS YouTube channel.
You will enjoy hands-on experiments, lab tours, seminars and workshops designed to develop your skills, give your brain a workout, and get you collaborating with the other students. The program features activities from across the breadth of STEM. Past ISSs have included:
For information about the selection criteria, see the section below.
Up to 70 students from across Australia will be selected to take part in ISS 2028. Selection panels in each state and territory will assist in the selection of students, based on the following criteria:
Our selection panels will make decisions based on the above criteria, as well as aiming for a balance of participants based on gender, location, school system and relative opportunity.
All selections are final and at the discretion of the University of Sydney and organisers of the ISS program.
Aboriginal and Torres Strait Islander peoples are under-represented in science and engineering in Australia. For this reason, the ISS organisers aim to select talented, enthusiastic Indigenous Australian students for the ISS, to develop their STEM interests, discover future careers and meet like-minded scholars from across Australia and around the globe.
The ISS Indigenous Australian Scholars Program reserves five scholarships to attend ISS2028 for Aboriginal and Torres Strait Islander applicants.
The selection process for these scholarships is simple.
To apply as an Indigenous scholar, you will need to upload evidence of your Aboriginal and Torres Strait Islander background when you apply. This can be any one of the following:
More details of the Indigenous Scholars Program will be available when the applications open in January 2028.
Gathering scholars from across the globe, getting them to Sydney and settled into the accommodation, and making sure everyone is healthy, safe and having a good time is a huge job, and something we take very seriously – which is why we bring together an amazing team of staff to make it all happen.
The ISS Staffies are a dedicated team of enthusiastic, talented and highly skilled young people. They will accompany you throughout the ISS to make sure you’re happy, healthy and safe. Many of our staffies are past ISS scholars, and, in most cases, pursuing STEM degrees at university – so they’re a fantastic resource ready to answer your questions about uni studies and careers!
Our dedicated and highly experienced overnight staff team is on hand at the accommodation to keep an eye on the scholar group, provide support and care, and attend to any problems or concerns.
The ISS Leadership Team – our Director Dr Chris Stewart, the ISS Project Officer, and an amazing group of talented people in the Faculty of Science's Partner Engagement and Outreach portfolio – together throw an enormous amount of effort into making the ISS an amazing and inspiring fortnight.
All expenses for accommodation and transport related to the ISS program are for the entire duration of the International Science School (up to two weeks), all our scholars with accompanying staff stay in boarding facilities close to the University of Sydney. This includes all scholars who live in Sydney.
Rooms: Students will share single-sex dorm rooms with up to three other students, giving them the chance to make new friends from across Australia and around the world.
Meals: three full meals a day (and a few snacks to keep you going), catering to different tastes, needs, medical conditions, allergies and diets. Don’t worry – if you have particular dietary requirements, we can handle it!
Travel
How you get to us will depend on where you're coming from. But rest assured, unless you're walking, your travel will be covered!
Australian students: the ISS will cover your transport by plane if you live more than several hours away from Sydney, or by bus or train if you live closer to us.
International students: all scholars selected by organisations in their home country will have their airfares to Sydney paid for by those organisations. The ISS will meet overseas groups of students at Sydney International Airport and take them to their accommodation.
