Hi there
Welcome to Poms in Oz.
I do not know anything about nursing. As a Learning Disabilities Nurse, are you also an RGN or RMN? If your job can get you a visa, then your abolity to get a vsia in then your ability to get a visa in the field of nuring will get you a sponsored job/visa, I strongly suspect. Australia is very keen to attract Health professionals of all types.
Please see these links:
Is your occupation in demand? - Workers - Visas & Immigration
A-Z Occupations List - Australian Skills Recognition Information
If you are not on the MODL, you may be on the wider ASRI list. If you think not, try "Welfare Worker", perhaps?
What sort of envoronment do you work in, please? By that I mean a hospital, school, helping people in their own homes - this type of thing?
Even if nothing in the ASRI list looks promising, all is not necessarily lost. In this event, the RSMS visa is an employer-sponsored visa which gives Permanent Residency in Australia from Day One, subject to various conditions. An employer-sponsored subclass 457 visa gives Temporary Residency only, but it can be a patheway to a
PR visa. With these two visas, it is possible to get DIAC to accept a wider range of skills than is possible with the visas which havefewer strings attached to them.
However, doing this may entail being willing to consider "rehional" Austrlaia. Which does not include Melbourne or the Mornington Peninsula but it does include Bendigo and Ballarat, for example.
If you are a Registered Mental Nurse, there are dozens of specialist nuring agencies in Oz that would be interested in placing you in a job and assisting you with obtaining a visa. Please see here:
