honeytea I would tread VERY carefully in those waters you're dabbling in. A lot of Australians have negative views of Aboriginals because we have no reason to think otherwise. I went to school with Aboriginal girls whom were lovely. I've worked with people of all ages, and both genders of Aboriginal descent. But I have met 10 times more people of Aboriginal descent who are wanting to make a quick buck and not work by crying poor simply because they are Aboriginal.
I worked for the department of housing for a couple of years and the amount of abuse I received upon asking for proof of tribal descent to fast track a council housing placement would shock you. Reverse racism is rife and it's hard to not become jaded when the experience of growing up you can't walk through certain parts of town simply because you will be screamed at because you are white.
Yes, Aboriginal people have been treated abominably by the British, and yes, their culture needs to be supported (and largely is. I learnt more about The Dreamtime than British history at school) but entitlement is a big issue.
On the topic of moving, the cost of living has shot up, as has the value of the Aussie dollar, so maybe tally up the things you do on a daily basis and convert the costs. Do you have a coffee out every morning? That can be $5. Husband have lunch at work everyday? That's another $60 a week. A decent meal out for 2 will set you back about another £60, depending in where you live.
Also be aware if you're stationed somewhere, you could actually be about 80 miles to your closest 'town'. It's not uncommon to have to do a least a 20 minute drive just to get milk, if your out bush.
It sounds great, but it's a very different lifestyle.
