Try to get up to the Central Highlands, Chris. It's not on the Giro route, and I love the area. Some steep climbs (which you'd enjoy), but some really hidden gems.
As Machka says, we are looking to get over there for a bit early next year. I am missing the place like anything, and the uncertainty over jobs is keeping me from moving back there.
Maxxxie, the Giro route is a good way to see the island, but don't be afraid to divert off to areas that may interest you.
