Welcome to this group and forum, Pete. I've noticed you about on another motorcycle forum I poke about on.
TJ knows stuff, but this time for the "Memorial dedication in Wilcannia" he has his dates wrong, methinks. From the thread: IBA Australian Memorial Site - Netallie Hill "Our first meeting will be a special dedication on 28th September 2019".
For our BB2500G, my wife and I rode to the NT, then rode, 2 up, north out of Alice Springs to Pine Creek and back. There are many possibilities.
I'm already looking forward to the Naracoorte Muster in April, it's the time a few of us gather at one spot.
