Nissan Datsun Sports Owners Club (NDSOC) had some support behind the 2006 event. Was initially a 20th Anniversary thing for R31 owners, but now its a bi-annual event. 06 we had the Prince Car Club, R31 Club, SAU members, Gibson replica cars (DR, HR31 and GTR32) and more . Cazz Krueger (GTS145) organised the last one, and is organising this one, with the track event being held at Winton Raceway.
Also hearing rumors that the 2010 event is going to be held in Adelaide...............
