What confused me was the following:Provide these documents at time of application lodgement if you are applying for this visa through the Temporary Residence Transition stream.
[h=3]Skills and qualifications (must hold at time of application)[/h]Your skills do not need to be assessed because you have already worked for your nominating employer for two years in Australia.
Registration, licensing or professional membership, if required for your occupation in the state or territory in which you will be working.
Documents from the relevant Australian registration and licensing authorities that show you hold, or will be able to meet, necessary registration and licensing requirements. The documents must specify both of the following:
the type of registration or licensing held
the name and contact details for the registration or licensing authority.
That's why I wondered did a mechanic need any of the above.
Thanks
