Thanks Glen. There will be 4 to 5 road bikes and we're in our 50's A little bit of "good" dirt wont hurt, one of us on a K1600GTL might disagree so we are pretty much road oriented. We will have travelled from Tassie. Thinking up the coast and back inland. Being conscious of the hot weather and how it knocked a couple in the group around on a recent trip to Alice Springs, would try to take small steps (200-300 km) and have a good look around. Hoping to park the bike for a few days and check out the local scenery/beaches. Not sure how far north to go, doesnt seem to make much sense to keep going north and "frying". We have 5 weeks all up so might be able to lose a few days north and spend a few more leisure days south of Perth. Going south from Norseman looks like - Norseman/Albany, Free day at Albany, Albany/Margaret River via Augusta, Margaret River/Perth. Free day in Perth.
Appreciate your thoughts.
