The 35-year-old batsman, who led the team in the absence of regular skipper Pat Cummins, will continue to play Tests and T20 internationals.Smith told his team-mates of his decision to retire immediately after Australia's four-wicket defeat in the Champions Trophy 2025 semi-final against India in Dubai on Tuesday, having top-scored with 73 in his side's 264 all out."It has been a great ride and I have loved every minute of it," Smith said in a Cricket Australia press release.After making his debut against the West Indies in 2010 as a leg-spinning all-rounder, Smith went on to play 170 ODIs, scoring 5,800 runs at an average of 43.28.He smacked 12 centuries and 35 half-centuries, and was a member of Australia's 2015 and 2023 World Cup-winning teams."There have been so many amazing times and wonderful memories," Smith said."Winning two World Cups was a great highlight along with the many fantastic team-mates who shared the journey."Now is a great opportunity for people to start preparing for the 2027 World Cup so it feels like the right time to make way."Test cricket remains a priority and I am really looking forward to the World Test Championship Final (in June), the West Indies in the winter and then England at home. I feel I still have a lot to contribute on that stage."
