But, if you want a short 1 line breakdown of each, here we go...
Sydney: Known for its famous harbour, warm weather and cosmopolitan vibe. You’ll never be far from the beach or a gym, that's for sure. Sydney beach suburbs are full of surfers and there’s always a barbie nearby.
Melbourne: Known for its hipster vibes, world famous coffee and artsy laneways. Melbourne is a city with a tonne of character & a very European flair. This multicultural city was rated ‘The World’s Most Livable City’ 7 years in a row.
