I came of age in this fantastic city, living here for five years in my late teens/early 20s, so I have some big love for this part of the world! I always say that Sydney is Australia's version of Los Angeles (compared to Melbourne being its New York) - hot and sunny, health and body-conscious, entertainment and plastic surgery capital. You get the idea.
It's a pretty dreamy city to live in, and while it has risen over the last decade to become a costly place to live (and visit), you can still have an amazing time just enjoying being outside in the sunshine, taking in the beauty of your surrounds.
Spread out over so many areas, the sky-rocketing house prices are transforming the city as people push out into areas beyond the usual Bondi/Surry Hills/Newtown circuit, which means there are many exciting new places to explore.
