Depends what you are after, you can be on city beaches and feel like your the only one living here!At the same time you can be in with the crowd say at one of the many events held in the early winter months, tour down under, fringe, film festival, wine festivals, music festivals.
I originally lived in Uk for most of my life then Perth & have been in Adelaide for a a few years.
So here's the top five things about Adelaide.
1) Its hot
2) You can swim for 6 mths of the year (gets lovely on those 40c + stints)
3) It has shopping centres, but not on the scale of Melbourne or Sydney
4) Lots of desert approximately 50kms out of the city (excluding the ocean). So you can get away from people, campings great (but the shrub does start to look the same after a while)
5) Cold beer in cartons fresh from the drive thru.
Not the worse things, but factors:-
1) Its dry & although it does get green in winter, within a month of no rain its a dirt bowl (specifically outside of the city area - where limited trees grow, mostly scrubland)! We had 10 days of 40c + this Feb, a record of 45.8c, so when your complaining about 10days of 30c day in uk, you haven't seen nothing just get someone to turn a hairdryer on and follow you around for a few days, that hot wind is hitting your face! We actually had blackouts/electricity because of the lack of infrastructure & demand of airconditoner use during those periods (it still a country town with a 1.5million people!)
2) No pub atmosphere (that goes for the whole of australia). only in the uk thats wot we are famous for :-)
3) People hibernate from June to September (but dont forget u have no pub socialising)
4) The city is growing at such a rate that you can spend an hour commuting into the city from north & south suburbs (80miles from North to South is the urbanised area), the trains are appalling & they put this crappy film on the windows so you can't see out, as are the bus lanes and the south australian drivers are the worse in the country so forget the bike.
5) You have limited direct flights out of the country. And apart from New Zealand you won't be doing any cheap holidays out of this continent. Return airfares to LA are in the region of 2K aussie! 14hrs flight from Sydney, so a day by the time you have connected. Okay there are cheaper airlines now but limited specials.
6) You will pay ($3) 2 pounds for a big bar of Cadburys & $1.50 (1 pound) a litre for fuel, as you do a lot driving distance this can be a massive expense.
7) I know alot of people who are still earning only $40,000 a year and the median house price is $400,000 so 10 x your earnings. The rental market is only 1% vacancy rate so you will spend alot of time bargaining for a rental property you like (i.e. more than asking price).
But don't forget you can swim in the ocean for 6 months of the year - (longer if your an iceberger - 80yrs + doing the winter months).
I'm happy but you know i've realised it doesn't matter where you are in the world, its who you are with, the people that are in your world and contentment at the end of the day. Lifes a journey, you have to try different things, but eventually you realise that things aren't that different.... some people make an effort others just expect...
Live the dream
