The decision follows the proposed transfer of fromer Australian left-handed opener Matthew Elliott, who has been offered an opening batting/coaching role at South Australia.
Elliott's move was blocked by Victoria and the case will go to a grievance tribunal hearing next month. The Victoria chairman of selectors Michael O'Sullivan expressed concern over the fact that the players could be poached and offered significant pay rises just to be called an assistant coach.
Meanwhile, James Sutherland, the CA chief executive, said it was essential the positions were valid and the new Memorandum of Understanding (MoU) would outline how much could be spent on players and coaches.
"It's important that those payments are bona fide and there may be some speculation about some of those payments," Sutherland told AAP.
"We have looked at those in the past and will continue to look at that to ensure they're bona fide and appropriate and that the amount of money that is going to players is the right amount."
Sutherland added that explanation has been sought from Tasmania, who employed Michael Bevan as a player/coach last summer.
