i live in sydney atm but lived in both... it's more prettier here and the weather is great, beaches are awesome, nightlife is fine also depending what your into but it's fuckin expensive to live here. a shitty 2 bedroom apartment close to the city will set you back 2 - 2.5 k aus a month . people are ( really generalising here) more arrogant and stuck up also..... more a money, husstle busstle look out for no one but my self, party till i'm an arse then spew in a cab on the way home sort of vibe in the city
melbourne isn't as pretty, weather sucks 4 seasons in one day. but living there is sooo much easier than in sydney people are more relaxed have a more a sports, arts, music, cafe/restaurant based city life.. just sorta seems people are more friendly , night life really does shit's on sydney .. public transport is alot easier than in sydney, there are big parts of sydney not serviced by public transport and without a car life can get frustrating as it covers a really really big area .
brisbane is a big fuckin country town

hot and humid as fuck even in the middle of winter it's fuckin hot half my family live in QLD they ask me to move there.. no chance in hell cheap though.
perth is very pretty but it's the most isolated capital city in the world i do hear really good things about it though
both have pros and cons and no matter what you choose living in australia is the best.
