Yass to Nowra

The shortest way is the Hume to Sutton Forest then cut across through Kangaroo Valley. Nowra to Nerriga is a nice new road but it's gravel in parts between Nerriga and Braidwood. I haven't done via Tarago.

Hi Russell. Bit more info in these old threads 84142 95379 Cheers,Bob

If you go Tarago then Nerriga you will have approx 5 km's dirt road (if that) and then the low level crossing over the Shoalhaven river (single lane and closed if river is up). If you get to the river and crossing is closed then you will not be able to turn around and will have to master reversing up hill and around narrow blind corners.

Road from Braidwood to Nerriga would be fine if you don't value your van or have a week to transverse slowly. :)

Kangaroo valley would be the easiest way as long as you take it easy and watch for trucks at the eastern exit of the valley prior to heading down to the coast proper (bad corner), given this though as other have said many a truck and van transverse this road and do so without incident
Enjoy your trip

The best way would be Tarago to Nerriga. There is very little dirt road left, approx 5kms. And although we have had rain recently the crossing is under the road. You could also call in to or ring the Braidwood police station or ring the Nerriga pub for up to date info on the crossing.
