Of you find yourself in Rockhampton with time to spare then it is definitely worth the visit. Went for the Cathedral Tour which is a 1 hour guided tour and was not disappointed. The tour guides were pleasant, patient and knowledgeable. They were even nice enough to accommodate me when I turned out to be the only person who came for the tour and they had a minimum of 2 people policy. Would have wanted to do the Geo tour package as well but unfortunately did not have enough time.
Best time to visit is during the Summer Soltice (late December to early January) where apparently the sun lights up the cave in quite a spectacular fashion.
