You have to take into consideration a few things
You have to renew your driving licence every so often. It is not a life time one like the UK. It's $70 (47.00gbp)per year here (Adelaide - which is generally thought of as the cheaper state)
You have to pay to see the dr. We have to pay $60 (40.00gbp) per visit & penicillin cost me $20 (14gbp) for dd when she was a baby.
There is no affordable dental care. If you are on low income, you get a health care card, but have to wait 2yrs for an exam. Or you can pay privately, or take out (costly) health insurance.
There are property taxes (but no council tax)
No TV licence. But you get 4 channels of crap...unless you get foxtel, which costs, obv.
Food cost a lot. Organic food costs more. And it is rising.
Eating out is reasonable in some places.
Clothes/books/electricals cost a lot. It is cheaper for us to get books sent form the UK, with postage costs!
You have to pay for education as well as book lists that the school asks you to buy.
I love it here, but it is getting very expensive. And yes you may end up earning more, but comparable to your cost of living, it work out to the same, really. We are planning to come home asap.
One of my main concerns is education. Dd1 is getting an adequate state education, (we can't afford private). There seems to be no world education, they are taught very much about what goes on in Australia & that's it. Most People I have met here think that if it doesn't happen in Australasia, it hasn't happened.
People say that the weather is better, ell yes it is...but in the summer we are stuck inside due to 35 -43 degree heat. And today, we are stuck inside (as we have been all week) due to rain etc. So, it is what you make it. I'd rather be out in the UK, in summer rain, than out here in 43 degrees!
A1980 Most of your info is incorrect. It certainly takes us a lot longer to get to the city. You cannot get a huge house with a pool for $250K. Not a nice one, in a nice place, any way.
I don't consider it dull, but dh does.
There is a lot to consider, op. Things that you don't find out during a holiday. You really need to dig deep.
My friend had a $180k mortgage when I first moved here (she bought her house years ago) and her repayments were $4k A MONTH. Because interest is so much higher here. Worth thinking about.
