Decent condition up to the E-Main/E-100 turn off. Afterwards the road closes in and looks quite narrow

First washout
Driveable (4wd) with some potholes to turnoff between 3.5km and 4km. Past that it's still driveable for a few hundred metres with some mild pinstriping and rocky sections.

There is a washout at the 4.5km mark that will stop all vehicles except quads/bikes. There are two more washouts at 5km and 5.8km. Past around 5.8km alders will stop any off road vehicle.

Road is drivable by a 4WD, SUVs or even 2WD up until the spur to Seed Peak. Only after this point is when it is heavy cross ditched and access is extremely difficult - as per earlier reports.

Half bridge
The road is for the adventurous. The start is a little overgrown but not much. There is one deep ditch passable in a short to medium wheel base 4x4. I did it in a stock 3rd gen 4runner. Then there is one half bridge, half logs and half dirt. After the just a few rough spots up to Dunkeld trail head.
