Upgrades At Sydney Airport

[David Wallace]

Forgive my ignorance, but I was at the mound today and noticed several cranes that appeared to be working in the vicinity of the International Terminal Carpark. I haven't been around Sydney Airport for about a year. Are these cranes within the confines of the airport or are they outside the airport and the angle of the photo just makes them appear to be next to the airport?

Sorry if this has already been discussed.
