A skills assessment is required for Electricians migrating to Australia so they can apply for a visa to work in Australia as an Electrician. The Electrical skills assessment is the way Australian Immigration can confirm that you have the relevant Electrical skills to match the Australian guidelines.
Even if you don’t require the Electrician skills assessment for the purposes of a visa, you will need it to become a registered Electrician in Australia as you require the OTSR to obtain your registration which is a mandatory requirement to work as an electrician in Australia.
