Stanlake was ruled out of the series decider in Sydney after sustaining an ankle injury in the warm-up before the washed-out second T20I in Melbourne on Friday.
Left-armer Starc played his last T20I against Sri Lanka away in September 2016.
Australia, who lead the three-match series 1-0 after winning the opener in Brisbane, already have Nathan Coulter-Nile, Jason Behrendorff and all-rounder Marcus Stoinis as pace options but captain Finch said Starc would be considered.

"(Starc has) got so much experience in the limited-overs games as well and we’ve seen how dominant he can be when he gets it right with the ball," Finch told reporters in Sydney on Saturday.
"We’ll have a look at the wicket this afternoon and discuss the side but coming straight off a Shield game with an eye on the first test, his preparations will be really good."
Australia face India in a four-match test series starting in Adelaide on Dec. 6.
