Any DAS has to be accountable and disposable, must meet Ministerial and Industry benchmarks that set performance based salary paid annually, (set also as is the contract tenure but open to Ministerial renewal). Must report directly to The Minister and not sit on The Board. (which should be sent to the local pub with a 12 drink stipend to meet every ten years to discuss pot plants). The Minister should prepare a performance report to Industry every six months that is open to response.
No senior bureaucrat would agree to that. Who did you have in mind?
