“This Test match needs to proceed, and in the interim we will continue to investigate this matter with the urgency that it demands.
“As I said earlier today, Cricket Australia and Australian cricket fans expect certain standards of conduct from cricketers representing our country, and on this occasion these standards have not been met.
“All Australians, like us, want answers and we will keep you updated on our findings, as a matter of priority,” concluded Sutherland.
On the board decision to appoint an Acting Captain, Cricket Australia Chairman, David Peever said: “The Board of Cricket Australia has endorsed Tim Paine to step in as Acting Captain for the remainder of this Test.
“Both Steve and David will take to the field today under Tim’s captaincy.
"Given the admission by Australian captain Steve Smith, the ASC calls for him to be stood down immediately by Cricket Australia, along with any other members of the team leadership group or coaching staff who had prior awareness of, or involvement in, the plan to tamper with the ball,” ASC chair John Wylie and CEO Kate Palmer had said in a statement earlier in the day.
