I agree with Genius - prefer Qantas Lounge for the freshly cooked to order food and the better wine (they have some even nicer bottles kept in the back for regulars!). Gets busy until about 8pm local time when the Sydney and Melbourne flights clear out. Another T1 tip if you have time is 'The Jewel' which you have to go to before security - it's connected to T1 and has an indoor rainforest, a crazy waterfall and lots of good shops and restaurants - a fun way to kill an hour before the lounges.
