I am a semi skilled refrigeration engineer in the U.K and thought it best to get some certificates before leaving the uk ,Just about to do C&G 2078 and 2081 air conditioning install ,commisioning and service.

Do I need a licence In W.A. as you do in the east ?
If so how easy is this to obtain ?
How well will i do with this trade ?

Anyone in this trade or knows someone for advice and reassurance? Going in september starting to panic!!!!!!
