I have a few mates up that way but I have never been up there in my Nav yet. From what I know there is still allot closed from the floods but I would probably just grab a map and ask around in the town like the servo or general store. If you go through Stawell call into Rayners Mini Market, its a fruit shop opposite Miter 10 on the Hwy. My mate Ben runs the place and he is a mad 4x4er he could give you some idea of where to go. I think he is in QLD for the next couple of days but should be back by the end of the week.
Hopee that helps a little
