When I moved from Sydney to Melbourne I was stunned by how "foreign" Melbourne seemed. I might as well have moved halfway across the world! They really are such different cities, but there is a lot to love about both. (Er, except for the exorbitant rents and house prices.) I was fresh out of uni, and Melbourne lured me with its huge dance scene, live music, amazing food and its attitude to anyone and everyone of "You have your own style, your own thing going on, so enjoy it, indulge it and we'll embrace you". That was 35 years ago, and I'm still in Melbs, because all these things are still true. But I also love visiting my family in Sydney and hand-picking the best of that city.
Sydney: Good things are the beautiful beaches, the national parks that surround the city, the walks (if you're visiting, do the Hermitage walk from Rose Bay to Vaucluse, the Coogee to Bondi walk and the Spit Junction to North Head walk), yummy Asian food, especially Thai; ferry rides on the harbour; shopping and admiring Victorian architecture in Newtown; galleries in Chippendale; the Museum of Contemporary Art, followed by a hike around the Rocks; the Art Gallery of New South Wales and the Botanic Gardens next door.
Cons are the high rents, long and costly commutes due to the tricky topography, and a nightlife heavily dependent on alcohol, thanks to the rubbish liquor licensing laws. Fine if you love your booze. (Awful for danceaholics like me, which is why I left.) The climate has changed, hence a lot more rain. Homophobia. Arrogant, entitled men, especially in the eastern suburbs. Insufferably hot, humid days, especially out west, where it can be 12-15 degrees hotter than on the coast.
Melbourne: Inner city focused for music and nightlife, outer suburbs for big nature walks and urban farming. Great streetscapes for socialising and hanging out; people are sometimes described as "a Smith Street, Collingwood person" or a "Chapel Street, Windsor person". Variety of nightlife, everything from garage punk to the glossiest show from Broadway. Big touring productions start in Melbourne because we have the talent, theatres and audiences to support them. Music for all tastes. Lots of niche restaurants and weird bars. Public transport is quite good, meaning you can live in a far-flung burb and get around town reasonably quickly. High-performing public schools. Seven universities. A long-standing culture of welcoming newcomers and letting them add their distinctive thing to the city. Interesting beaches along Port Phillip Bay, each with its own character; I like Dendy Beach and Half Moon Bay. Some lovely outer suburbs such as Montmorency, close to the mountains yet with a bohemian village feel. Heaps of bicycle tracks, walking trails, easy weekend trips to goldfields cities such as Ballarat and Bendigo. Cons are, again, high rents and house prices; infrastructure that hasn't kept up with pop growth; a changing climate, meaning Melbourne has become hotter and drier. I'm wondering how much longer they'll be holding the Australian Open tennis tournament in January, when it is truly, unbearably hot.
