When dropping my dad off yesterday at the Perth airport, yes on his way to Bali again, look out Bali Mr.John is on his way, I noticed a very long queue to get into the carpark. Cars were parked everywhere, staff directing people where to go. Luckily we were doing a drop and run but it did seem very hectic. Not sure if there was a lot of flights going and coming or what. Looked like a part of the far right carpark was missing and a lot of landscaping going on??? Maybe if you are going to the airport get there early or check the website for details.
