A side strain has reduced the hard-hitting 24-year-old, also a lively seamer, to the role of a spectator at the tournament so far.
But Faulkner, who injured himself in Australia's 112-run tri-series final win over England in Perth last month -- a match where he smashed a 24-ball 50 not out featuring four fours and as many sixes -- bowled several overs in the WACA nets on Monday and, provided there are no ill-effects, he should be available to face Afghanistan.
"I bowled a couple of overs (last week and was) pretty close, the difference is the intensity of an ODI (one-day international).
"I will have a solid hit out today and hopefully I recover well and be out here (at the WACA) on Wednesday afternoon."

He added: "I think I was lucky being a left arm bowler and a right arm batsman, it wasn't the same side (bearing the strain) when I was batting."
Faulkner's recovery is timely for Australia given fast bowler Pat Cummins is set to miss Wednesday's match after he suffered a side strain during the thrilling one-wicket Pool A defeat by New Zealand in Auckland last weekend.
But with Shane Watson again under pressure after giving his wicket away against New Zealand and Glenn Maxwell not making much of an impression at Eden Park, Faulkner could replace one of his fellow all-rounders.
"I'm not too sure what they want to go in with, that's purely up to the selectors," Faulkner said. "All I can control is about getting back out on the park and giving myself a chance of playing again.
"The rest isn't my job and it's not for me to worry about. That's their decision at the end of the day."
