Excellent.
My favourite is Club Home (
http://www.homesydney.com.au/), and the best clubbing night there is Sublime (
http://www.clubsublime.com.au).
It is 3 levels completely decked out with everything you could want in a club - awesome LCD screens with trippy shit, colours, cameras of the floor and DJs etc. Really top end sound system and laser setup. 4 seperate areas for different genre's and 3 bars! Capacity for just over 2,000 I beleive - can't go too far wrong.
