Welcome Jack,
The next outing for the Sydney branch will be a motorkhana event at the Penrith Regatta Centre car park on Sunday the 4th of August. You can find the details in the link below.
Club Event Calendar : Cobra Car Club of NSW
Of course the big one is the Nationals on the October long weekend at Goulburn where you could pretty much see it all.
It's well worth a visit if you want to compare makes.
cheers
Paul
