My team and I had the opportunity to visit both the U.S. team responsible for ESTA and the Australian immigration department to talk in depth with them about their experiences in setting up those two systems. We spent a very helpful full-day session with the U.S. Department of Homeland Security, and they took us through their experience in setting it up, how they went about it, communications, IT solutions, and so on. That was very helpful. The Australian government was equally able to share a lot of aspects.
