A very nice rural road with some nice corners and scenery. Be wary of the locals that use it, they know the road and happily tear along at the posted speed limit of 100kmph. I reckon the road should have been designated 80, but this stretch avoided that, 100 is quite quick along this road.
Be wary of school pickup through Bunninong. There are hundreds of distracted mothers picking up kids, hundreds of aggravated tradies trying to get ahead of everyone, and buses everywhere. Once into Buninong the traffic is light.
