Australia's latest limited-overs big hitter, Glenn Maxwell, has the technique to carve out a future at Test level, according to Australia's batting coach Justin Langer.

Maxwell made his one-day international debut against Afghanistan in the United Arab Emirates last month and was out for two. But his scores of 38, 28 and 56 not out in the ODI series against Pakistan which followed have put the youngster in the spotlight.

Maxwell didn't get a bat in Australia's wins over Ireland and West Indies in the group stage of the World Twenty20 last week and took a combined tally of 1-29 off three overs with his offspinners.

However his 27 off 20 balls after being promoted to No.3 from game three of the T20 series against Pakistan in Dubai earlier this month -- in Maxwell's debut T20 international series -- showed the cool head of a big-game player.

"There's a lot of 'rah rah' about Glenn Maxwell and that he's a very confident sort of guy," Langer says.

"But fundamentally he's got a very, very good technique. He plays with a straight bat, he's got very fast hands and he's quite a student of the game.

"He can play off the back foot, he drives well, he can hit the ball out of the park.

"Talking to him, he's a cricket nut and I love that. The thing about the Michael Clarke story and the Ricky Ponting story, they're cricket nuts.

"They've played cricket since they were little kids so there's layers to them.

"He's going to be a good player. I love his attitude."

Maxwell averages 45.29 in 11 first-class matches with one century.

"I hope he gets six hundreds to really push his name up (for Tests)," Langer said.

Never mind that his teammates have nicknamed him "The Big Show".

Langer says Maxwell has shown with his match-winning half-century in the ODI game against Pakistan that he has some real steel about him.

"With youth comes fearlessness often and he seems to have that but what I love about him is his temperament," Langer said.

"He played like he'd played 150 games."

Maxwell wants to prove people wrong that he's a Test player, like David Warner.

"I know a lot of people earmarked me as a Twenty20 and one-day player," he said.

"Once I get back to Australia and play some first-class cricket I'm hoping I can put some big scores on the board that people just can't refuse."
