Hey Henry I'll give you a challenge, tell me one thing in Melbourne that is better than Sydney. I can tell you plenty weather, beaches, harbour city. The only thing I can think of is SL restaurants in Mel are better than Syd.
Forget all the list I have been to Melbourne and no way in the world will I move from Sydney to Mel. Look at your weather cold and gloomy. Look at Sydney full of sunshine, I don't even need a jumper in winter. Look at all the waterfront homes in Sydney can you compare that to Melbourne.
