The 39-year-old, an attacking opening batsman and capable offspinner, is 11th on the list of the world's leading ODI run-scorers with 10,290
In his 330 ODIs, he has hit 22 hundreds and 47 fifties. He has also taken 106 wickets.
A relative late-comer to international cricket, Dilshan made his ODI debut in 1999, featuring as an allrounder, batting mainly in the lower-middle order for a decade.
Given the chance to bat up the order, he firmly established himself in that position and often gave Sri Lanka a flying start to innings.
The right-hander is capable of shots all round the wicket, including his trademark 'Dilscoop' where he flicks the ball directly behind himself.
Dilshan played in the 2007, 2011 and 2015 World Cups, finishing as a runner-up in the first two and a quarter-finalist most recently.
He retired from Tests in 2013 and is set to be available for the two Twenty20 internationals with Australia that follow the ODI series.
