We will be going on the ETA Business visa, so nothing illegal there.
We will have enough funds for us for 3 months out there and yes we will be booking a return ticket. Our children are 1 and 2 so they are pretty easy and are not missing out on schooling. He would take a sabbatical at work, so whilst we are out there we are still classed as employed so we would be earning the months needed to add to our qualification.
He is qualified with 3 years but only 1 year post qualification, so companies can either see him as young and fresh or inexperienced.
We would leave everything in the UK with no intention to return so we wouldn't have any extra costs left in the UK.
I am aware it a risky plan, we are now looking into contracting as they have more sponsorship options, I weren't sure if vetassess would assess us if we got our Skills Assesment in OZ as Vetassess only requires 2 years post qualification and TRA need 3 years hence why we have to wait another 2 years.
