DO NOT DO THIS FLIGHT.
Whoever scheduled this flight needs to have his/her own special place in hell reserved for them.
Amen, brother, amen!
But in all seriousness, much depends on how much sleep you think you are likely to get. If you can sleep most of the way to Sydney, so that you can hit the ground running the morning that you get there, then choosing an evening flight is a no-brainer. This is how I always do it now, if flying direct.
