Senator Pocock thank you for waiting again because I wish to give accurate advice to the chamber. Updates to the protocol and treaty text itself are considered a treaty action and require consideration within Australia's treaty-making framework. Updates to the guidance material attached to the protocol don't, and, if that guidance material was updated, Australia would be obliged to incorporate that into our own practices. That ensures that the parties to the protocol collectively keep up with advances in the way that the protocol is to be implemented.
