One aspect of GA that declined rapidly a few years ago was the overseas pilots coming for flying holidays.
This was because of the difficulty in getting documents verified for an ASIC when the applicant is overseas, but worse was moving the issue of a Certificate of Validation or Special Pilot Licence from the regional CASA offices, where it took around 24 hours, to Canberra where it can take several months and still not get done.
My last flying tourist, with an FAA and JAA PPL gave up after 9 months of trying to go through the process and getting nowhere; they took her money though. So, there is no point in marketing aviation tourism any more
