FineWine:
As a senior nurse in Sydney in 2013-14 tax year I earned double what I earned in my first tax year back in NZ 2014-15.
My brothers youngest 41yr son has been working the mines in WA since early 2000's started from nothing with no skills or qualifications except 5th form NZ School Cert. He is now a mines project manager and pulls over $250,000/yr and his wife is a mines geologist and earns about the same.
My nieces 19yr son has just started work in the mines in WA, via the afore mentioned uncle. No skills or qualifications except NZ NCEA and the, must pass, compulsory mining pre-employment intro courses provided by the employer. He is now earning as a bottom of the ladder employee $105,000/yr. They are 12 hour shifts starting at 0500 and he FiFo's up from Perth. Not to sure about how many days on/off.
If he keeps it up he will be on the Perth property ladder before he his 25yr.
A pal of mine went to drive diggers in WA around that time, lured by the big bucks,
One thing you don't hear about is the cost of living. He said 'feesh and cheeps' cost $20, as did a jack n coke at the pub.
On average Aussies do earn more, but if you're after a high income, can you seek that out here, through training and specialisation?
My brother works in the NZ oil and gas industry - the working conditions resemble the mines, weeks away from home in harsh environments.
He earns good money but he's paying a price of that.
Having said all that, if anyone believes the grass is greener, go and try it out, especially if you're young and not tied to anything.
I couldn't think of anything worse than living my whole life thinking, I should have done that when I had the chance.
