You must be nominated by an employer whose business is lawfully operating in Australia.
You must be employed to work in the nominated occupation and in a position within the sponsoring business or an associated entity of that business, located in a designated regional area of Australia.
Before you can apply for the visa, your employer will need to lodge a nomination application for you. They will only be able to do this if they are an approved work sponsor or have at least lodged an application to become a standard business sponsor.
