I think the essence of the response given last time when we gave witness testimony was referencing the fact that the nature of policy development is not necessarily linear and continuous, such that it has a defined start and end.
That is all a way of saying that the process of developing something, all of the options that got assessed and the advice that was provided to the minister during the course of it—this was actually prior to my joining the unit itself—has been going for more than two years. That's an easy estimate.
