Thanks for taking the time to share that Lyn. I'll link the creation story of the Rainbow Serpent for anyone who wants to know more.

We didn't see them this trip so we must go back with the camera and tripod, they hang from the wall and ceiling so you do get pretty close to them. You just have to hope to have no one messing around with a torch when you are there, you need to cover the lense and keep it pointed down when you are close to them or they think it's day time and turn off their bum lamps.

Hi James, thanks for visiting the site. The only reason swimming isn't allowed is to protect the wildlife especially the glow worms. They are most concentrated on the cave ceiling and walls but they also live in the creek embankment and surrounding rocks and vegetation. When people clamber through the area to get to the ponds or touch the cave walls and embankments when swimming they crush and kill the glow worms or adult flies / eggs that will produce the next cycle of glow-worms.

Hi Stephanie, we are very lucky to have so much unique wildlife even around some of our bigger cities. I hope you make it back here some day, it is a huge country to see in one visit.
