David Warner has announced his retirement from one-day international cricket in the lead-up to his final Test match.

The veteran opener said the time was right to conclude his ODI career following Australia's 2023 World Cup triumph in India, where he was the side's leading run-scorer.

Warner had been contemplating retiring since before the tournament and went public with his decision at a press conference on Monday ahead of his Test swansong at the SCG this week.

"It was a decision that I was very, very comfortable with," the 37-year-old said.

"To win in India, from where we were, was absolutely amazing.

"When we lost two games in a row in India, the bond just got stronger with each other and it's not by fluke or by chance that we were able to get to where we were.

"So I'll make that decision today, to retire from those forms (ODIs)."

Warner retires as the sixth-highest run-scorer in Australian ODI history, having amassed 6932 runs from his 161 matches.

His 22 centuries are the second-most by any Australian ODI player, behind only Ricky Ponting, who made 29 in 105 more innings than Warner played.

If called upon, Warner would be open to making a comeback at the 2025 ICC Champions Trophy in Pakistan.

The Champions Trophy is among the only pieces of silverware missing from Warner's resume; the last time Australia won it in 2009, he was not yet a lock for selection in the XI.

"If I'm playing decent cricket in two years' time and I'm around and they need someone, I'm going to be available," he said.
