Really? I come from the tropics moved to Aus (Melb) in my early teen, I can't see my self living anywhere else now. Actually went back to the old country earlier this year and I couldn't live in that humidity, great to go for a holiday (short-term) but can't see myself staying long-term. Hubby also, who is from NSW (Newcastle area) prefer Melb to Sydney. I love this city so I'm bias, always one of the top rated most liveable cities in the world.
But yeah it can be a downer if the weather is gloomy like today.
I can see her living here, she will get more work here at least and Ballina is really not that far away.
