Batsman Shaun Marsh has expressed gratitude after a superb stretch of form for the Perth Scorchers earned him a recall to Australia's Twenty20 International squad for the series against Sri Lanka this month.

Marsh topped the country's premier domestic T20 tournament run-scoring ranks, scoring 412 at the impressive average of 58.85 across nine matches. The impressive string of performances accrued a healthy strike-rate of 128.75 - and five quickfire half-centuries.

January's success marked a stark turnaround for the 29-year-old, who was dropped from Western Australia's first-class unit - and Perth's Twenty20 setup in the wake of disciplinary issues at the Champions League in South Africa.

"A few months ago I wasn't even picked for WA and I was doubting myself and stuff like that. It's just great to play well for the Scorchers, get my name back up there, get the confidence back and I'm really looking forward to playing again and hopefully doing well," said Marsh.

"I was in a pretty dark space there for a few months. It certainly challenges you, but it's made me a stronger person within and it's made me a better person. I've worked really hard and did some boxing with a mate of mine, trained really hard and made sure I was doing the extra sessions.

The 13-man party selected for the two-match series also brought recalls for batsmen Aaron Finch and Adam Voges and seamers Ben Laughlin James Faulkner. All-rounder Ben Cutting, meanwhile, earned a maiden call-up.

All-rounder Shane Watson was not considered due to a calf injury - and there was no space for the veteran David Hussey, with the selectors instead opting for spinning all-rounder Glenn Maxwell.

"We've kept a pretty close eye on Shaun and he's in a very good place at the moment. His batting has just been wonderful. We hope this is a stepping stone for other forms," added national selector John Inverarity.

"It was a toss-up in September at the World T20 and Glenn was preferred to David in all games but the semi-final at the end. When it's very close we always go for the younger player."

The opening T20I gets underway in Sydney on Saturday and will be followed by the second and final fixture in Melbourne two days later.
