Sure is a lot of money. As a point of comparison, in New Zealand, RAANZ's total annual fee is $65 ($51 AUD) per member, less than just RAA's employee cost per member.
Admittedly, RAA probably has a lot more administration to take care of, given it's larger memberhsip base and the differences in regulation (primarily RAA having to deal with aircraft registration, which is done by the CAA here).
But still, that's a heck of a lot of money. There's something to be said for volunteerism!
