Hi I’m an electrician now living in Adelaide.
firstly you will need to get hold of a company that can provide a Offshore Technical Skills Record (OTSR). Our migrant agency put us in touch with Vetassess who are a Melbourne based company. At first you will be asked to provide evidence of that skill which will include letters from employers, letters from college to prove attendance, certificates of qualifications, etc for recognition of prior learning. It ends up being a sizeable folder. You have also got to have been working in the industry for the last 5 years. Once you send that off they will assess it and if you pass that part you will be asked to carry out a practical exam and theory exam. Once you have passed that you will then receive the OTSR.
This allows you to transfer your skills over in Australia where you have to complete a regs course on the Australian standards which includes practical and theory exam which is generally a 3 week course. you will also need to document at least 6 months work in the electrical industry while you are here to then qualify for a Electrical license.
whilst you are completing all this you will be on a restricted license so you can only be classed as a Trades assistant while you are sorting that out.
hope that helps a little
