There is the Stinson/Point Lookout/Stretcher Track option. I have walked the Stinson Track as a day walk and there is a campground there; I believe you can book it through QNPWS. It's an interesting walk with a lot of history to it.
There is another a camp area further up the mountain at Point Lookout, from where you could return to Christmas Creek via the Stretcher Track.
Neglected Mountain is also in the Christmas Creek/Running Creek area and people do camp there overnight (I don't know if they're supposed to) which could be another option. There are bits and pieces online about it but I haven't done it myself.
Rat-a-Tat is very nice.
however lugging a pack up the darlington range is very tiresome!
Second, third and fourth that. More clingy lawyer vines, mis-interpretative signs and false trails than the Planning and Environment Court. Cheaper, though
