Greetings Qantas qurus!

I finally have 2 First class award tickets for next September using CO miles.

As this will be my first experience in a true internation First and on Qantas, I have some questions for you folks...

The transpac flights I have found enough info on. (but if you would like to share suggestions, comments, etc.. please do)

However, since I have 4 legs in domestic business I was wondering what this service is like? What are the seats like? (I'll be flying 2 763's, 1 742 and 1 733)

What kind of meals can I expect on flights at 7am MEL-SYD, 9am SYD-CNS, 1pm CNS-SYD, 7am BNE-SYD?

Also, Melbourne and Cairns are my first 2 stopovers enroute to Sydney. Will I be granted access to the domestic QF lounges based on those segments being part of a greater internation F itinerary?

Terminal 3 at SYD, is 35 minutes enough for a connecting flight (MEL->SYD->CNS) in the am on a Thursday?

Do the QF lounges or airports have smoking facilities or does one have to go outside?

Thanks guys, any and all thoughts/comments appreciated.
