Spotting locations at the International Terminal?

[Robbie J]

Apart from the rooftop of the two carparks, can anyone recommend good spotting locations at the International Terminal?

There was an elevated vantage point for spotting inside the terminal, above an outdoor seating area near a bar. (There was even a lift to take you up to the top.) Is it still there?

Any other good locations worth perusing?

I'm hoping they will install some new spotting platforms around the airport as part of the 'Sydney Gateway' road project that is currently under construction.
