Girraween Bush Campsites

Hi all,
Planning on heading out to Girraween in June for a 3-day circuit, hoping to camp at bush sites away from the hordes at the main camping areas (I'm sure it will be packed over the long weekend). What are the nicest bush campsites to stay at? I have a vague plan of heading out from the information centre past Mt Norman, camping at South Bald Rock site, bagging a few peaks in the eastern section and spending the second night at Underground Creek, before heading back. I've read that Twin Peaks has an awesome campsite but that there is not much space (there will be 2-3 small tents between us) so not sure if we would be pushing it to stay there instead of Underground Creek. Thoughts?
Cheers,
Munch
