Road Condition Query - Oberon to Goulburn

Am organising a trip to the MotoGP in October (for 6 bikes) and I really hate highways and I've done lots of the usual twisties so I'm looking for some new and interesting roads to take.
I've found a road that runs from Oberon to Goulburn (via Porters Retreat, Taralga and a number of other minor towns) that I'd like to give a go. I'm told that there is only 5 to 10km of dirt and it's quite good (told by a cage driver though so who really knows what it's like for bikes).
I'd really like to find out from a local if I can what the road condition is like and if it's a worthwhile ride.
Suggestions of other roads to ride would be most welcome too.
