Herveys Range Dev Road to Valley of Lagoons (nth QLD)???

Evening all. I'm looking to travel to the Valley of Lagoons (West of Cardwell/Ingham) from Townsville, but I'm thinking about taking a back road/track. From what I can work out, the route I'm looking at turns North off the Herveys Range Developmental Road between the Star River and Burdekin River. I've seen the sign for Paluma at the turn off but I haven't taken the road before. The road goes roughly North/North West and eventually links up to the Lava Plains Mt Fox Road, apparently.

I'm looking for any general info about the route. It seems that parts of it are pretty minor tracks, and other parts are pretty major unsealed roads. How difficult is the route to navigate? I don't have a GPS to help me. What type of condition are the roads/tracks likely to be in? Creek/river crossing difficulty and depths would be useful and any other information at all would be appreciated. We're planning on taking a single vehicle (80 series cruiser).

This is the general route, I think. It looks like the road crosses the Burdekin River at a causeway just north of Mount Foxton. Then I think it's supposed to run North, basically parallel with the Burdekin and then cross it again near the mouth of Oakey Creek (just west of the Running River mouth), but it's kind of hard to follow in that section. Then it runs north again, basically parallel to another Burdekin feeder creek, which I can't find the name of (the next creek west of Oakey Creek), before crossing that creek near a homestead. From there it runs generally North West and links up to the Lava Plains Mt Fox Road.

Thanks guys.
