Sri Lanka won the toss and decided to bowl against Australia
Sri Lanka's captain Lasith Malinga won the toss and sent Australia in to bat in the first T20I at Adelaide Oval.
Malinga's decision meant David Warner would walk out to open for his first home international since the end of the Newlands ban alongside the captain Aaron Finch. Steven Smith is set to bat at No. 3 and Glenn Maxwell at No. 4.
Australia left out Ben McDermott and Billy Stanlake from their team after Andrew Tye was ruled out out of the series with an elbow injury, meaning Alex Carey will bat at No. 6 and the spin bowling allrounder Ashton Agar as high as No. 7.
As well as welcoming back Malinga, Sri Lanka elected to leave out Niroshan Dickwella, with Kusal Perera taking the gloves for the visitors.
