Soundtrack, I can only help you in SYD
as I was there last week.
What I would recommend is that you go to the departures level of the international terminal.
On the left hand side of the building, go to the sky cafe and watch for signs that take you to the observation deck.
There is a very nice observation deck where if you have a lens of around 200mm or so you can get some nice shots of landings and takeoffs on what I believe to be Runway 16R.
There also other ways to get around to good locations at SYD
but I didn't have a car and wasn't too adventurous. I just tried to walk to the threshold of runway 16R but turned back eventually because I didn't want to get run over.
I am currently developing the film from my spotting trip and hopefully some of my shots will be good enough to finally get uploaded on a.net.
Here is a useful weblink to the information that I used to spot at SYD
Anyway, here are some shots in the database that I believe were taken from the observation deck that I speak so highly of:
I'm not so sure about that QF
A330, if it was taken from the observation deck then thats a pretty good lens that guy has got. But I can vouch that the bottom two shots were taken from the obs deck.
Best of luck and let me know if I can be of any help.
