Hey David, Might be worth looking at the Skills lists mate. Pretty sure the government has taken most trades off it, due to the repercussions of COVID 19. Construction is Now down by 60%.
Also to be able to be invited to apply for a skilled migration visa you must have served a 4 year apprenticeship. No less. A lot of people fall short on that one silly requirement.
Once you can provide proof of those you will go through the Vetesses Route which means you’ll do their version of the AM2 (Capstone) in a centre over in the UK. That enables you to apply for a restricted licence in Aus. Then you’ll have to work as a TA for a year and complete a logbook to become fully licensed as well as completing there wiring standards the AS/NZ3000.
amongst that the Visa process is long winded about 18 months to 24 months for completion, plus you got to do an IELTS English test And the visa costs around 5000 pounds.
if I knew what I did today about the hoops I’ve had to jump through I wouldn’t have bothered TBH.
