Ed,
Launceston is only a few miles north of the airport. Once out of the city, the road to Barnbougle Dunes is very hilly and features lots of twists and turns, but the countryside is quite stunning ~ give yourself a few extra minutes drive time. I cannot recall which route I took, but I probably followed their advise. The directions on the website worked very well, and I did not have any trouble getting to the course.
For an added challenge, rent a stick shift, thank goodness the foot peddles are the same as in North America.
