Spectacled Flying-foxes

Cairns is home to 44 known Spectacled Flying-fox roost sites, however less than half of these are occupied at any one time.

Spectacled Flying-foxes play a crucial role in the Australian eco-system by being one of the most efficient pollinators and seed dispersers of native Australian forest trees. They travel great distances each night in search of food. Spectacled flying-fox roosts are mainly seasonal with numbers and composition of the camps changing constantly.

Like all native wildlife, flying-foxes are a protected species in Queensland under the Nature Conservation Act. The Spectacled Flying-fox is listed as “endangered” under the Commonwealth Environment Protection and Biodiversity Conservation Act and Queensland threatened species legislation.

No touch, no risk

Bats and flying-foxes may carry bacteria and viruses which can be harmful to humans but the risk of infection is low. The best way to avoid any risk of infection is - never touch a flying-fox.

If you do not touch flying-foxes or other bats, there is no risk.

Australian Bat Lyssavirus is rare and when infected, the bat soon dies.

You will not be exposed to Lyssavirus

  • when flying-foxes fly overhead,
  • when they roost or feed in trees,
  • if you come into contact with droppings or spats or flying-fox camps.

Lyssavirus can only be transmitted through deep tissue bites or scratches from infected bats.

Sound Machine

Council employs a Long Range Acoustic Device (LRAD) machine to assist with approved deterrent activities in Cairns City when required. The sound machine can be engaged from the very early morning before fly-in times or may also be use to lift flying foxes already resting in a tree, depending on circumstances and approval types.

The noise machine is a highly directional audio device which means the sound directly in line with the device is significantly louder than in the back and on the sides. The majority of the acoustic output power is concentrated in approximately a 30 degree cone in front of the device. Wherever possible, the device will be pointed directly at the intended target (i.e. up or towards the tree). Operators will maintain an exclusion zone when the device is in use.

Nearby businesses and residents can expect to hear sounds such as distant sirens, whips cracking, flying fox calls, construction noise, demolition noises etc. The greatest success has been found in using a range of different noises at various intervals.
