The 2025 Melbourne International Open will be held from April 7 to April 14, 2025 at the Melbourne Chess Club. The 2025 MIO is organised by Independent Chess Australia and consists of a 9 round classic, a 9 round rapid, and a 13 round blitz tournament.

The venue capacity is 180 players. The 2024 MIO reached capacity and so we recommend registering early to avoid missing out.

Registrations open at 1:00pm AEDT on Friday November 1, 2024. More updates will be provided as details are finalised.

We look forward to welcoming both new and returning players to Melbourne in April 2025.
