The Australian Rugby Union will make an official complaint to World Rugby in a dramatic aftermath to Australia's 14th straight Bledisloe Cup defeat.
Cheika suggested referees have predetermined ideas about his players and was left fuming by the refereeing performance of Romain Poite in Wellington as Wallabies skipper Stephen Moore struggled to get communication from the official.
The ARU will make an official complaint to World Rugby's integrity unit over a meeting between the Poite and All Blacks coach Steve Hansen before the Test, without their knowledge or invitation.
Under World Rugby rules, coaches are not allowed to meet with referees before games unless their opposition is given notice and the chance to also attend.
The Wallabies will allege Hansen met Poite without telling them, which would breach the law 15.4.2 which reads: "Any meeting with the referee involving participating Unions before any International Match, may only take place if a representative of both Unions involved in the Match is present, unless one of the Unions, having been offered the opportunity to attend a meeting with the referee elects not to do so, in which case the meeting may proceed with a representative of only one participating Union present."
