Aviation tourism ie overseas pilots coming here for flying holidays/safaris was booming until CASA moved the Certificate of Validation process to CLARC in Canberra. What used to take a couple of hours to validate an overseas licence can now take several months, if it gets done at all. No reason that I can see why anyone in CASA should be involved in this at all, but for as long as they are, self-fly aviation tourism will be a distant memory.
I see the site in the post above makes no mention of this or the requirements for an ASIC etc. Good luck to them.
