With regards to WAAC in Perth I made enquiries there with regards to renewing my UK JAR PPL SEP which had just passed its 5 year currency. (It would of course have helped if 2 months of back and forth with the UK CAA and differents answers from different people had not elapsed beforehand.)
Anyway they told me they do not have any licenced UK Examiners on staff and couldnt help.
I've been looking all over the Southern Hemisphere and had no luck whatsoever. If you do find one please let me know!!
