Hello Jack
Welcome to Poms in Oz.
The MODL is the list of occupations in greatest demand in Australia at present, so the first step is to look at the MODL, which is here:
Is your occupation in demand? - Workers - Visas & Immigration
There are two electrical trades listed, so next you go here:
A-Z Occupations List - Australian Skills Recognition Information
Match up the Job Title, Code etc and see whether you think you would qualify under either of the MODL categories.
If not, fear not because it is not essential to have a skill which is on the MODL in order to migrate to Oz.
Have a good trawl through the ASRI list and see what you think from that would fit your skills, qualifications and experience to date.
Have a look at the DIAC website as well:
Workers - Visas & Immigration
Information Booklets - Applications & Forms - Visas & Immigration
Don't worry too much about the intricacies of Vetassess for the moment, I'd say. Get a "feel" for the whole business of migration first.
I would also suggest that you should ring up two firms of Registered Migration Agents. The first is Go Matilda in Southampton:
Go Matilda - Your Gateway to Australia - Contact and Feedback
The other is Ian Harrop & Associates near Oxford:
Registered Australian Migration Agents, UK - Ian Harrop and Associates
If you ring Ian Harrop, use the Burford number and ask for Tony Coates or Ian Harrop.
Both of the firms above will be happy to chat with you on the phone for 15 minutes or so, at no cost to you and with no obligation on your part to go any further with them. They can give you a pretty good steer in just 15 minutes, you would find, which saves a huge amoung of head-banging on your own!
Best wishes
Gill
