Good luck with your group as it could be just what you need.
There was an attempt at a Datsun site in Canberra i think, [turbodatto??] but it looks to have folded due to a lack of interest there.

Keep our old 'Datsuns alive in good old Van Diemans Land. Come to think of it, whatever happened to "Luv_my_68_wagon_1000". Hes a Tasmanian & another possible candidate for your group.

edit... I finally got Ruo's site name right.
