Landcare is a non-governmental community movement dedicated to preventing land degradation and achieving sustainable land management. It consists of a network of local volunteer groups of which there are over 1700 in New South Wales alone. Each group works to find local solutions to local problems such as salinity, soil degradation, animal pests, weeds, vegetation loss, waterside erosion, poor water quality, coastal degradation and urban land degradation. If you appreciate how lucky we are in the Helensburgh district to enjoy a relatively unspoiled bush environment you should also be aware that it is under serious threat. read more

Helensburgh Glowworm Tunnel

Helensburgh Glowworm Tunnel is currently open. However, it is very wet and muddy. Gum boots are recommended. Beware of trip hazards both outside and inside the tunnel. Please read below for what is prohibited in the tunnel and surroundings.

Helensburgh Glowworm Tunnel is a local treasure that houses a population of Arachnocampa richardsae. You can read information about glowworms here.

You can read information on the history of the tunnel and old station here. 

Glowworms are found only in Australia and New Zealand, and are not actually worms, but the larvae of a primitive fly – the fungus gnat.

Stranded by the retreat of the ancient Gondwanan rainforest, they only survive in dark humid places like this tunnel. 

The bioluminescence (meaning ‘living light') is produced by the glowworms. They produce long, sticky threads to catch midges, mosquitoes and mayflies that are drawn to their lights.

Glowworms only glow when they feed and their best displays are usually during the warmer, wetter months of the year.

Glowworms are very sensitive to changes to their environment. Exposure to lights, smoke and insect repellent stops them from glowing and feeding, and can kill them.

Helensburgh Glowworm Tunnel is usually open. However, it is always wet and muddy and if you are visiting it, you are advised to wear gumboots. After heavy rain, the tunnel may be flooded.

The following are prohibited in the tunnel and surrounding area

  • the ignition of flares, fireworks, steel wool or any flammable or combustible material
  • graffiti
  • smoking, use of insecticides or insect repellents
  • flash photography
  • directing torch light at the glowworms
  • the use of drones
