Pros: Most livable city in the world. Great startup scene. Phenomenal transportation options. Great universities. Fantastic street art everywhere. Amazing food. USD vs. AUD is quite good for USD right now so it is pretty affordable.
Cons: Internet not blazing fast. Beaches elsewhere in Australia are much better (it is on a bay = no waves).
