I'll speak firstly about the transport instruments, which I think are probably the most significant innovation brought through by this bill. The bill introduces transport instruments, and they're a way of enabling the Minister, in the case of transport rules, or the Governor-General, technically, in the case of regulations, to delegate responsibility for specified aspects of those rules and regulations to a named lower-level authority. So we have regulations and rules, which are set through a fairly fulsome process, as pieces of secondary legislation that are granted in the primary legislation. The rules are about then saying what are very detailed and prescriptive things that actually could be dealt with at a lower level by the transport agencies. I'll talk a little bit about some of the areas in which these might be able to apply, but, broadly speaking, it's making sure that the system can be as efficient and adaptive as it can be.
