Natural Bridge's Cave Creek restricted access area

Why close access to the creek and creek bank?

Safety

• Natural Bridge has a history of serious injury and death associated with the cave and creek. This includes reports of three serious injuries from slipping on rocks since 1998 and the drowning and near drowning of two visitors in 2004.
• Swimming in the creek and access to the creek bank is now prohibited—penalties apply!
• Prohibiting access to Cave Creek and the creek bank will reduce the threat of injury or death due to:
  • slips and falls
  • drowning/near drowning
  • hypothermia or shock from unexpected water temperature.
• Cave Creek lies beneath a section of potentially unstable rock face, which is predicted to send rocks into the creek if it falls. This rock face is monitored by the Queensland Parks and Wildlife Service (QPWS) staff and when required, geotechnical engineers.
• Prohibiting access to the creek substantially reduces the threat to visitor safety.

Conservation

• Entering the creek bank vegetation and swimming in the creek harms the glow-worm and microbat population as these activities affect their food. Glow-worms and microbats rely on insects for food. Insect larvae and eggs live in the silt of the creek bank and when trampled by people walking along the creek bank, they are washed away during a wet season.
• Pollution from visitors using insect repellent, sunscreen and leaving rubbish in the creek harms the insect food source of the glow-worms and microbats. Cave Creek is home to several frog species including the rare Australian marsupial frog, which may also be affected by visitor pollution.
• Pollution from visitors is also detrimental to the cleanliness of the water catchment.
