Australia head coach Justin Langer confirmed Stanlake's place in starting XI, with frontline pacer Starc to miss the game because of his brother's wedding.
Stanlake has represented Australia in 17 T20Is so far, in which he has scalped 25 wickets.
"At this level, where he lands them is more important than the pace. That said, with someone who comes as high as he does, he has got that natural pace. That's why he's such a great prospect for us," he added.
In the first T20I played at the Adelaide Oval on Sunday, Australia rode on powerful performances from David Warner, Aaron Finch and Glenn Maxwell to register a commanding 134 run win over Sri Lanka.
Starc in that match had finished with figures of 2/16 from his four overs and helped Australia restrict the visitors to 99/9 in their full quota of 20 overs.
