Hi MFC_STE
Welcome to Poms in Oz.
I know nothing about IT but I do not trust "free on-line assessments" myself. They tend to be based on very general parameters and so not all of them are reliable.
Also, IT seems to be a minefield with lots of different sections to it (none of which mean anything to me.)
For the sake of $50 or so you could get ptlabs (Peter Chiam) to do you a proper skills-appraisal based on your actual experience to date etc. He is a computer-expert as well as a Registered Migration Agent (plus a very nice guy.) His website is here:
Ptlabs Consulting
Having sorted that bit out, Peter would then be able to advise you on your visa options. If whichever visa it boils down to is not one that he deals with himself, he would refer you on to an Agent who does deal with the particular visa involved.
This is how I would set about the process if I were in your shoes.
"Regional Visa" is not specific enough, honey. You could be describing more than one visa. Please see here:
Visa Options – Professionals and other Skilled Migrants – Workers – Visas & Immigration
You might mean the subclass 475 visa, but that seems to be capable of running for 3 years?
You might instead be describing a subclass 457 employer-sponsored temporary visa and be looking for the qualifications/work experience exemption from that? Please see here:
Visa Options - Employer Sponsored Workers - Workers - Visas & Immigration
The qualifications exemption for all 3 of the subclass 457, ENS and RSMS visas is here:
Employer Nomination Scheme (Subclass 121/856)
It sounds to me like you would be seeking to take advantage of this one:
the position is so unusual or highly specialised that a suitably qualified employee with three years post-qualification experience cannot be found
Presumably the location of the job would make the position suitably "unusual" but since this is not skilled independent migration, you would first need a job offer from an employer who is willing to sponsor you for a visa.
Can you be more specific about which visa has actually been suggested to you, please?
Best wishes
Gill
