Tax withholding can be up to 46% of that.
You do get national healthcare, but it isnt superb and most who can afford it opt to use private hospitals and docs.
So essentially, you will pay more for food, gas, clothes, electronics, beer...Everything! Because Oz imports like nobodys business.
In exchange, you get fairly nice folks with funny accents and a country full of animals that kill you. Even the dang ol Drop Bears which we think are cute and cuddly.
Oh you yanks and your fear of tax

The top tax bracket is 45% for any dollar earned above the 180,000 dollar a year mark. So if you earn 182,000 you are taxed less for the 180,000 and 45% on the 2000 above the bracket. As you move down through the brackets its becomes less and less.
On the kind of wage you'll earn in ambulance I estimate an overall percentage of about 22%. If you don't wanna pay that, then that's fair, you can have your American system (how does your income tax compare to 22%?), but lets not bang on with that old "they take half your money" stuff.
We do pay a fair bit for goods and services but you will not be worrying too much about petrol and groceries. You can raise an average 2 child family with relative comfort on the basic paramedic (EMT-I) base wage. Some paramedics here (read: most) will complain that you can't, but it is a relative matter. I was on placement once with a paramedic who complained endlessly about how hard it was to support a family on his wage. Later we visited his lovely large home in a nice neighbourhood, his wife (who didn't work), their three children, their two cars and plasma TV. We can earn significantly above the national average wage. Initially at least, I will earn ~10k more than my friends moving into the business, IT and economics world after their degrees and actually get paid for the time I work rather than earning a salary and being expected to do unpaid OT like everyone else. Unless they become particularly successful, I may always earn more than them. I will probably earn more in my first year of qualification (2 years from now) than either of my parents have ever been paid. We live perfectly comfortably.
Also, if you are injured at work, or have a health complaint that is work related (backs?) you're entitled to workers compensation and if you cannot return to work, they will retrain you.
As far as the animals go, I wouldn't worry about it. Unless you 'go walk-about', a 1000 miles from the next person, you're pretty right for the most part. I've spent a bit of time in rural areas, camping and so on and I have never been bitten, stung, attacked, or even seen any of those nasties...except for drop bears...they will kill you...and they are everywhere.
So what is the pay? And if possible relate it with cost of living to USA money so others that might be thinking about this can have a realistic ideal.
On internship the base rate is 54k, 64k when you qualify. It raises with experience and with different roster types. In South Australia (best pay) the base rate is 88k :blink: . Rising to the MICA level (what you would consider Paramedic) sees a relatively minor pay increase about 72k. It is important to realise though that most people earn more than this. It is almost impossible not to earn overtime here and there, and you get extra money for broken meal breaks, taking students etc (you just have to fill out the paper work). Some basics earn as much as 100k.
As far as I can tell this does not include superannuation (which is the compulsory contribution to employee retirement funds made by an employer based on a percentage of wage). This increases the worth of a given wage considerably given that you do not HAVE to salary sacrifice to save for retirement or for any future healthcare expenditure.
When you say those wealthy enough chose to pay for healthcare, it means that we employ private insurance companies, we still receive many of the same services as public patients, we simply pay less for them, and get them quicker. They also cover dental and optical expenses, that are not covered under the public health system. It is not at all similar to the concept of paying for healthcare in the US. Also if you employ private insurance companies, you pay less tax for the public healthcare system.
