The measures that Oz is taking to curb night-life, drunkenness and violence is very similar to the Crown Dependencies of the UK I have lived in before; complete lock-down on late-night parties by restricting licenses and sale of alcohol.

Until you can find a way to party safely, quietly and being sober at the same time I would just give up and on trying to change government opinion and save your money for places that want your partying business like Europe or other parts of Asia.

Things only started changing in London around 7 or 8 years ago when the trouble with squat (unregulated) parties became more costly to police than by allowing regulated parties.........if your partying population is able to sustain this kind of change then great, if not then prepare to travel for all your adult leisure needs.
