In the Uk I supported a family of 4 on £30k in Leeds, here in Brisbane up until May I was on $70k inc super
Over all I would say the money allowed me an equivalent lifestyle in Australia to back in the UK
In support of the 2.2 argument the price of food here is about 2 times but depending on what you buy and when can vary hugely. Fresh food is very seasonal here, where in the UK we have become so used to importing all our food we expect equivalent pricing all year round.
This argument is endless, you always get the people with unrealistic expectations and the others with doom and gloom no one can live on this kinda money ect ect... at the end of the day you live to your means, if you earned £30k in the then you can live the same here on $70inc super which is about $63k. Assuming you don't move to Perth, the economy there is crazy right now and you need more like 3 times your UK salary to amount to the same thing.
I know this because I live here and have been earning pretty much 2.2 times my UK salary for the past year.
My wife got into this same argument on Saturday with a load of her expat friends, they were all "oh how expensive everything is here" and will never listen to reasoned arguments because they just don't want to hear it. There will never be a resolution to this argument until people are willing accept evidence based arguments which frankly they are not.
Example 1. Bread oh it's sooooo expensive here compared to back home.. bread in the Uk varies from about 50p to £2.50 per loaf, in Australia it varies from around $1 to $4
For anyone worried about cost of living over here, just remember it's not cheap it's pretty much the same based on average salaries.
Here ar my comparisons:
New Mazda 6 UK 2007: £14500
New Mazda 6 Australia 2012: $31k
New Kawasaki er6f UK £5999
New Kawasaki ninja650r(same bike) $9999
Weekly food bill UK: £120p/w
Weekly food bill Australia: $200p/w
Gas/electric UK: £50p/w
Gas electric Australia: $25p/w
Petrol UK: £1.35 per litre
Petrol Oz: $1.40 per litre
Car insurance and road tax uk: £700 per year
Car insurance and rego australia: $900 per year
Mortgage at home £700 per month
Rent in Oz: $1440 per 4 weeks
New shoes for work UK £50
New shoes for work Australia $100
Mcdonalds meal UK: £4
Mcdonalds meal Australia: $7.95
I could go on and on forever with evidence and proof or the correlation of pricing and still there will be people on this board saying I live in cloud cuckoo land and that the figures aren't true...
Anyway I hope this helps someone to see the truth behind cost of living and not the doom a lot of people try to portay.
