In 2010, Amir was banned for five years for indulging in the spot-fixing scandal along with Salman Butt and Mohammad Asif.
Last year, after the conclusion of his ban, Amir made a successful comeback to domestic cricket and carried forward that success when he made a return to international cricket.
Stating that what Amir did in the past was best to be left in the dark, Warner said that Australia are quite aware of what Amir is capable of doing with the ball in hand.
“He (Amir) is just going to be another player.
“We know what we’re going to expect.
“We know what he’s capable of with the ball in hand.
“What is done in the past is in the past.
“We’re not going to try and go out there and get under his skin for something that’s probably not warranted.
“That’s best left in the dark.”
Amir’s return to international cricket was a hotly debated issue and players like Mohammad Hafeez and Azhar Ali were initially against the idea.
Warner added that since the Pakistan Cricket Board and the players have accepted Amir back into the national team, other teams will also have to accept the decision to give a second chance to the 23-year-old.
“At the end of the day I think you’ve just got to accept what their (Pakistan) officials have done and what their players have shown towards him (Amir).
“For us, it’s about going about our own business and what we can control.
“They’ve accepted him back in the team and you have to accept that.
“It’s like someone who gets done for drugs ... they’re always going to be given a second chance if that is necessary and if that is what players feel and the (players’) association feels, and you have to accept that.”
Pakistan currently have a battery of left-arm pacers with Amir, Mohamad Irfan and Wahab Riaz and Warner feels that Australia will have their task cut out against such a bowling attack.
The 29-year-old also added that the Australian batsmen will have to find a way to deal with Pakistan’s bowling attack and bat according to the conditions on offer.
“I faced him (Amir) in the Caribbean (T20) World Cup (in 2010) and I think he got me out second ball and he was bowling 150s (kph) then.
“Nothing’s really changed except he’s trying to swing the ball now.
“They’ve got three very, very good left-arm fast bowlers in their attack.
“It’s not just him (Amir), they got Mohammad Irfan and Wahab (Riaz).
“He (Wahab) is a fiery character as well.
“But we’ll have to wait and see what the conditions are like out there.
“They’re three very, very good bowlers and for the guys in the top six we really have to find a way to 1) score and 2) identify who the danger bowler is at the time and try and put some runs on the board.”
With one win from two games, Australia will take on Pakistan on the 25th of March in Mohali while their final game will be against India on 27th of March.
