During the first few times flying to Oz, I had difficulty to
sleep but after doing that so many times, I have got used to it and
would just sleep all the way. I did that the other day when coming
back from Darwin (4.5hrs flight). Mind you, I would not have got
served anything anyway since it was a budget airline. 
Oh really? I heard the Thai airline and Cathay airline serve
good food. Qantas is not bad either.
