The area you may be thinking of is Mt. Moffat National Park. It's an old cattle station reclaimed and has 4 or 5 camp-sites and heaps of old farm tracks. Plenty of rock formations (arches, pillars, etc) some aboriginal artwork, bush walks and some stunning views. And best of all no crowds, we stayed 4 or 5 days during April a couple of years ago and we only saw 3 other vehicles after we visited every campground.
Getting there, go to Injune and turn north-west several hundred metres north of the township and follow that road for 2.5-3 hours (majority unsealed). Its a long drive ( 10-11 hours from Brisbane) but its worth it for the solitude.
There was a ranger in residence but no facilities except for pit toilets and creek water, so go self-sufficient. Hope this helps.
