Hi Darcy,
The Midland Highway is the most direct route - 3.5 hours is about correct. The speed limit is 110 in most places, but many think it's double that. You could also get to Hobart via the East Coast, but it would take a bit longer and it's a bit out of the way. A beautiful drive all the same.
You're going to miss the Shannon's Car Show in Hobart, I think it's on next weekend.
Where are you staying in Hobart, and how long for? I'm sure Weddo (the president of the early Holden Car Club of Tasmania) may be able to quickly pull a run together.
P.S. Weddo, if a run can happen, can I be a passenger in (one of) your car(s) please (mine's still having the wiring done)?
Kind regards,
Josh
