For one thing lets get it straight, it's NOT club rego. It's Special Interest Vehicle rego. Put in place by Queensland Transport for cars of over 30 years.
To be eligible you have to be a member of a car club and provide a dating certificate. If you club won't give you one then I'd write an open letter to the club informing them of their duty to the members and outlining your disappointment to their reluctance to issue one.
I too have heard nothing but bad stuff about the stuck up Mini Owners Club of Qld. A bunch of snobs who trailer their concours cars to and from shows. Like HDT say 'Drive your excitement.'
Have you guys thought of joining a Morris club that is not solely for Minis?
Maybe you could even join the Queensland Mini Car Club which has a very active branch in Townsville. This is the original club that sooo many people left a few years ago to start the Mini Owners Car club. The funny thing is that heaps are now coming back. Better the Devil you know I suppose.
Heres the contacts for QMCC,

Anyway just my 2 cents.
