What lights up the Natural Bridge cave in Springbrook National Park at night?

Answer: Glow-worms

Thousands of glow-worms light the cave. Never shine a torch on them; they stop glowing for up to an hour.

Glow-worms glow year-round, but the display is much smaller in winter. Smoke, bright lights and insect repellent can kill them. Swimming in Cave Creek is prohibited, and phone reception there is very poor.
