Mitchell Starc has pulled out of the second T20I of the three-match series against Sri Lanka in order to attend his brother's wedding.
Starc's absence paves the way for either Billy Stanlake or Sean Abbott to fill in the vacant pace bowling spot.
Cricket Australia granted Starc the release from the squad - a move which is in line with coach Justin Langer's increased focus on cricketers spending more time with their families.
The left-arm fast bowler claimed two wickets for 18 runs in his four-over spell on Sunday including a ripping yorker that got the better of Kusal Perera.
Australia defeated the tourists by an expansive margin of 134 runs in the first T20I and would be targetting an unassailable 2-0 lead in the next game in Brisbane.
Earlier, Andrew Tye's injury leading up to the series opener had prompted the inclusion of Abbott in the squad.
The 27-year-old last turned out for Australia in an international game five years ago but his comeback might be delayed given vice-captain Pat Cummins' insistence on persisting with bowlers better equipped with delivering a short ball barrage.
"(Bowling short is) something we speak about, no doubt, especially at the Gabba or Adelaide Oval, where it's quite fast and bouncy," he told reporters on Monday.
"And all our bowlers are 6 (foot) four (inches) or 6'5."
Stanlake stands at a towering 2.04 meters as opposed to Abbott, who measures 1.84 meters.
Regardless of which of the two bowlers gets his chance in the starting XI, the dispirited Sri Lankan batsmen will be wary of Australia's buoyant pacers.
