Apologies if this question has been done to death .
I'm currently awaiting a decision on a subclass 600 Visa. My brother is PR and has been for 15 years . He's married with kids to an Australian , Has an income of $200k a year plus $400k savings so no reason for it to be refused. I'm looking at changing this 600 into a 457 in about 6 months time . I've been told by moire than a few contacts that the 457 is easily gainable up in Pilbara if you're willing to do the **** jobs but just wondering if anyone knows how easy it would be to go from a 600 to a 457 . Long term i'm looking at settling in Australia and will do that via my Australian girlfriend but we havent lived together for the required amont of time etc and currently our time together only classes as 'dating' . Any words of advice would be greatly appreciated.
