This authority (TRA) have 2 requirements 1 qualification 2 job experiance.
One can get qualificaion diploma or trade qualification by student visa in au , but the matter of concern is how to get job exp in au ??
A person who hold a diploma or trade qualification in an occupation from SOL and if it meets to requirement of au standard they can get an special visa 485 , http://www.immi.gov.au/Visas/Pages/485.aspx
A person can get 485 visa by assessing their qualification 1st from one of 4 job ready programe assessment
Job ready programe >>> http://www.tradesrecognitionaustralia.gov.au/Programs/JobReady/Pages/default.aspx
1st assessment >>> http://www.tradesrecognitionaustralia.gov.au/Programs/JobReady/Pages/Step-1---Provisional%20Skills%20Assessment.aspx
if a person getting positive result in 1st assessment , they can apply for 485 visa , and in that visa they can cover the requirement of job exp which is required for perm visa , And after getting job exp in 2nd 3rd and 4th one they will assess everything for perm visa and if a person getting positive result in 2nd 3rd and 4th they can get permanent visa , I am not sure how many points can be earned on it IMO just 10 ,
Thanks for reading....
