What sort of Cert III is it mate?
 
Pretty sure that WES does not evaluate trade qualifications, had the same issue with my partner (Cert 4 Aircraft Engineer).
 
He is in the process of getting his qualification here in Can now, I ended up being the main applicant and didn't use his education for points.

I think one of the providers does do trade qualifications. Have you looked at all of the options on the CIC website, I can't remember which one it was - I know they were slower which is why I investigated WES first.
 
I called WES and they don't , and then I called ICES which is BCIT and they don't either. So i'll give the red seal ago I guess
