Hi Basil
As I understand it your husband is a high-flying investmet banker who would have to work in Sydney because that is where the international investment banks all have their Australian bases?
If so, and if one of these banks wants his skills more than he needs a job with them, you should be in a very, very strong bargaining position and, I would venture to suggest, you should also have some "corporate client based" RMAs acting for you and helping to negotiate the best possible deal with the bank.
Sure, you might not have identified which bank yet but for example Ashmore Brown act for some of the banks. I know they act (or used to) for the Macquarie Bank but I don't know which others. Please see here:
Macquarie Group Australia
Ashmore Brown & Associates
I would imagine that Mr Brown in their Sydney office would be your man.
But what happened about the skills assessment that you were considering with the help of ptlabs? Did the computer people refuse to accept it or something?
It is a while since you and I spoke but my impression is that whatever the score might be with the visas, you might find that an experienced RMA can get you a much keener deal with a bank than you might be able to get by yourselves.
Or have a word with Alan Collett, I firmly suggest. If Hubby is young and therefore not yet senior enough to be able to write his own ticket, don't forget that Alan Collett was a Chartered Accountant before he became a Migration Agent, is a CA in both jurisdictions and I would think he would have a very shrewd idea of what sort of deal Hubby ought to be able to command. You would need to contact Go Matilda in Melbourne, where Alan is based.
I'm a tad surprised that you seem to think this is DIY turf, though.
Best wishes
Gill
