Lots of those RAAus aircraft are not going to stand up to much training use. RAAus itself is going the way of CASA, after all it is a mini CASA and wholly owned by CASA, instead of an organisation promoting the flying of ultralight aircraft on behalf of its members. Many of its members are unhappy about its direction.
All of these recreational aviation organisations cannot help themselves when CASA offers them some regulatory powers and the chance to act like policemen. Many of the members are apparently former Stasi informants who are ever ready to dob people for not complying with some stupid rule.
My advice to any young people wanting to do aviation either recreationally or professionally is to move to the United States if you can.
Part of the malaise in GA is that until the last couple of decades it was able to utilise the left over infrastructure from WW2 flying training in the form of instructors, airfields etc. That is now gone or needs refurbishing. GA is still the best way to get around inland Australia from one country town to another.
Driving is now a pain with stupid speed limits and enforcement of same (random taxation to pay the salaries of those doing the enforcing - we used to hang highwaymen -now they are in uniform) resulting in frustrated drivers who aren't paying attention.
