Australian cricket team in New Zealand in 2023–24

The Australia cricket team toured New Zealand in February and March 2024 to play three Twenty20 International (T20I) matches and two Test matches. The teams contested the Trans-Tasman Trophy, with the Test series formed part of the 2023–2025 ICC World Test Championship.

The teams contested the Chappell–Hadlee Trophy, with the T20I series formed part of both teams' preparation for the T20 World Cup in June that year which will be held in the USA and West Indies.
