its a permanent resident visa which allows me and my wife along with kids to work and live in Australia permanently :)
oh I see - can't give you an advice to be honest - I know nothing about the job market in Australia - but judging from your English you would cope there
maybe do what Dominic says - it definitely depends on how much savings you have - I think applying for a job in Australia already now wouldn't hurt even if you don't quit your current job right away
it definitely is a good move career-wise to move to Australia and also Australia offers better future (including better education) for your children
