The 23rd Biennial Computational Techniques and Applications Conference (CTAC2026) will be hosted and organised by the School of Mathematics, Faculty of Science, at the University of Sydney in partnership with ANZIAM, the Australian and New Zealand Industrial and Applied Mathematics Division of the Australian Mathematical Society.
The meeting will provide an interactive forum for researchers interested in the development and use of computational methods applied to engineering, scientific and other problems. The CTAC meetings have been taking place in Australia biennially since 1981, the most recent ones being held in 2024 at Monash University and in 2022 at QUT. They have been a major regular event in the community of computational mathematics in Australia.
