Coachboy, I think this has been covered in another thread somewhere....my two cents....I find that , if travelling direct to SYD with only a refuel stop in Asia, then arriving in the evening leaves me less jetlagged, irrespective of how much sleep I get on the flights. I check into the hotel, shower, go meet some friends and get some beers into me, and then wake up at a reasonable hour the next morning.

To me this is far preferable to arriving at 530am AEST (having been woken at 330am for breakfast) , because by 4pm in the afternoon I'm having to prop up my eyelids with matchsticks....and then waking up at 4am the next morning anyway. Of course, I'm also not as young as I used to be....YMMV !
