My friend group had gone on our Normal Friday night drive together. John, Aaron Rach and myself. We'd been driving all night and we stopped at the falls just going onto midnight Saturday morning. It was a full moon, windy and cold. We hung around to enjoy the sight of valley from the lookout. It was bathed in moonlight and was very peaceful with the waterfall flowing next to the look out. We were about to leave when one of my friends decided he needed to pee and decided to relieve himself off the edge of the lookout as the rest of us walked back to the car. We hear him calling out to someone before he turns and calls out to us. Saying "Hey guys I think they're are campers or people at the bottom of the falls and I just peed on them I feel so bad, I didn't see them." We walked over and looked down at the base of the falls. The base is about 120 metres (390 ft) down. We look to see what initially look like blue/white torches in the dark walking through the rainforest towards the base of the falls. We call out to them asking how they're night is. But we get no reply. As well look closer we realised they weren't torches but glowing blue orbs. They then formed a perfect semicircle at the base of the waterfall. Once they formed the semicircle the glowing blue orbs begin to pulsate. We had no idea what we were looking at. We watched for 30 minutes as these lights pulsate. Then they started to come apart, or more turn into lots of little shapes globs of light. They returned into the forest moving like animated blood cells in vains. Then they were gone. We didn't feel scared, a little uneasy because we weren't sure what we had witnessed. But we joked on the ride home that we saw witches or fairies having a full moon ceremony at the base of the falls. I wasn't able to get a photo of the phenomenon my camera wouldn't pick them up clearly enough. But I have a photo I took before the phenomenon from the look out.
