Netting subsidy program extended to all NSW
The NSW Environmental Trust has announced that the netting subsidy program for orchardists has been extended to the whole of NSW, not just the Sydney Basin. This extension recognises that since the netting program began, unusually high numbers of flying-foxes have been occupying areas around Orange and other areas west of the Great Divide, and damaging crops.
More information on the flying-fox netting subsidy.
The program is being administered by the NSW Rural Assistance Authority (RAA). For more information, contact the RAA on 1800 678 593 or visit the RAA website.
What do they look like?
There are three species of flying-fox which are native to NSW:

The grey-headed flying-fox is easily recognisable by its rusty reddish-coloured collar, grey head and hairy legs. It is also the most vulnerable species because it competes with humans for prime coastal habitat along the south-east Queensland, NSW and Victorian coasts.

The black flying-fox is almost completely black in colour with only a slight rusty red-coloured collar and a light frosting of silvery grey on its belly. This species is more common across the northern and north-eastern coast of Australia.
Little red flying-fox

The little red flying fox is the smallest Australian flying-fox and has reddish brown-coloured fur. Little reds will often fly much further inland than other flying-foxes.
Where do they live?
Flying-foxes are nomadic mammals that fly across eastern and northern Australia.
Traditional grey-headed flying-fox habitat is located within 200 km of the eastern coast of Australia, from Bundaberg in Queensland to Melbourne in Victoria. In 2010, many grey-headed flying-foxes were found roosting and foraging outside these traditional areas; some were found as far inland as Orange and as far south-west as Adelaide. Researchers speculate that flying-fox movements could be related to food scarcity, nectar flows or seasonal variations, and are uncertain whether such movements will be repeated.
What do they eat?
Flying-foxes feed on native blossoms and fruits, such as figs. Flying-foxes are beneficial to the growth of vegetation, as they spread seeds and pollinate native plants.
National flying-fox monitoring program
The national monitoring program for the grey-headed flying-fox commenced on 14 February 2013. This is the biggest census of grey-headed flying-foxes ever undertaken across the species' entire national range. The aim of the census is to deliver a reliable benchmark on the current size of the grey-headed flying-fox population in 2013, and to monitor population trends in the future. All known grey-headed flying-fox camps will be visited and counted four times per year for the next four years using a standardised methodology developed by the CSIRO. The information collected will provide a better understanding of flying-fox populations that will be used to better manage community interactions with flying-foxes and improve conservation outcomes for this species.
Flying-foxes and commercial orchards
When food is scarce, flying-foxes will target any readily available food sources, including backyard and commercial orchards of stonefruit, pome fruit (such as apples and pears), lychees, paw paw and coffee.
On 1 July 2011, the NSW Government introduced a $5-million scheme to subsidise the cost of installing flying-fox exclusion netting for Sydney Basin and Central Coast orchardists, where impacts occur every year, to eliminate the need to issue shooting licences for flying-foxes. The subsidy has now been extended to cover the whole of NSW, not just the Sydney Basin.

Acoustic, olfactory and visual deterrents
Other deterrents include the use of:
- recorded sound (predator calls, animal alarm calls, loud and sudden noises)
- smells (e.g. carbide)
- lights (e.g. flashing strobe lights or bright light grids that may be movement activated)
- scaring devices (e.g. Bird Frite 12-gauge cartridges, models of birds of prey, reflective streamers).
These methods appear most successful when alternated or used together. However, flying-foxes are intelligent animals and may soon become accustomed to any device that has no apparent threat. Certainly in times of food scarcity, the only reliably effective method to prevent damage from flying-foxes and birds is netting.
The policy and procedural guidelines for the mitigation of commercial crop damage by flying-foxes, and information on applying for a section 120 licence, are available from 'Protecting commercial crops from flying-fox damage'.
From 1 July 2015, OEH will only issue licences to shoot flying-foxes as a crop protection measure where it considers that flying-fox damage to orchards is the result of special circumstances. Licences will be issued to shoot flying-foxes for the duration of the incursion, subject to strict limits.
The special circumstances are included here.
An independent review was commissioned in 2008 to assess the validity of the NSW licensing policy for the legal harm (including killing) of flying foxes. This flying-fox licensing review determined that shooting is only effective if small numbers of flying foxes are targeted and is a contributing factor to the decline of the species. In response to the review panel's recommendations, the issuing of licences to harm flying-foxes will be phased out. The phase out of licences is accompanied by a financial assistance package to help eligible growers with the cost of installing exclusion netting.
Flying-foxes in urban areas
Grey-headed flying-foxes are increasingly moving into urban areas in search of food and shelter, as a result of destruction of their natural habitat. This can sometimes be problematic for local residents, because of concerns about the noise and smell of flying-fox camps. Because the grey-headed flying-fox is listed as a threatened species in NSW, approval is required to disturb or relocate flying-foxes. A fact sheet about living with grey-headed flying-foxes suggests some simple measures that the community can take to minimise conflict when they are living close to a flying-fox camp.
Exposure to air temperatures over 40 degrees Celsius can lead to heat-stress and death from dehydration in all flying-fox species, especially in dry weather. Rates of mortality increase sharply at temperatures above 43.5 degrees Celsius, especially in flightless juveniles.
What should you do if you find an injured, sick or orphaned flying-fox?
If you find an injured, stressed or orphaned flying-fox:
To find a wildlife carer in your area, visit our 'Licensed fauna rehabilitation groups' page or the NSW Wildlife Council website.
What should you do if you find a dead flying-fox?
Do not directly handle dead flying-foxes. Where there is no direct handling or contact with flying-foxes, the risk of disease transmission is negligible.
If you find a dead flying-fox in a public area (e.g. on a road or in a park), call your local council to ask them to dispose of it.
If you must handle a dead flying-fox:
wear thick gloves (e.g. gardening gloves) and use a shovel where possible
wrap the carcass in at least two plastic bags before disposing of it
wash your hands thoroughly with soap and water afterwards
if you get scratched, consult your doctor immediately.
If carcasses are buried, they should be buried at a minimum depth of 15cm to avoid scavengers digging them up.
If you have concerns or questions about disposing of dead flying-foxes, contact your local council for advice on waste management in your area. In some situations, wildlife care groups might also be able to provide advice or assistance if they have resources available.
Any dead flying-foxes which are banded should be reported to the Australian Bird and Bat Banding Scheme. If you find a banded flying-fox, do not attempt to read or remove the band yourself. Instead, call your local wildlife rescue group.
Guidelines for councils and wildlife carers
During extreme heat events current best practice suggests that spraying individual heat-stressed bats with a fine mist of tepid water from a hand-held water sprayer when they are near or on the ground may be helpful. Spraying more broadly, of the camp or foliage, is not recommended. Spraying should only be undertaken by experienced, licensed wildlife carers who are vaccinated against rabies.
It is recommended that spraying does not commence within the colony until late in the day when the ambient temperature has dropped to below 35 degrees Celcius, This is because the added stress of human disturbance at higher temperatures can increase mortality .
Such spraying can cool individual highly distressed animals. However, care must be taken not to disturb or spray neighbouring bats, given spraying increases humidity and thus limits the capacity for evaporative cooling.
Flying-foxes should not be approached if they show any indication that they are trying to move away or escape from the presence of the sprayer.
Highly distressed individuals that do not respond to spraying may be removed from the colony by an experienced wildlife carer for more intensive cooling and rehydration.
Information for wildlife carers about OEH’s policies on rehabilitating injured or orphaned flying-foxes can be found in:
Flying-foxes in your backyard?
Flying-foxes should not be a problem if they visit your backyard. Residential backyards are rarely ideal roosting habitat for flying-foxes. They may enjoy eating the nectar from any native flowers you may have, or occasionally your backyard fruit, but they would generally not stay for more than a week or two.
If flying-foxes are causing problems in your area, contact OEH to determine possible actions. See below for advice on protecting your fruit trees.
Netting of garden fruit trees
Guidelines have been prepared to assist owners of backyard and commercial fruit trees in the proper construction of netting structures that will protect their trees from damage and minimise harm to native wildlife, including flying-foxes.
For more information, see Protect your garden fruit in a wildlife friendly way.
Flying-foxes play an important role in long-range pollination and seed dispersal of many plants. Loss of foraging and roosting habitat has meant that flying-foxes increasingly occur in camps in urban centres. The Flying-Fox Camp Management Policy 2014 (PDF 247KB) aims to minimise impacts on people who are in close proximity to camps.
We are consulting on this Policy – closing on 1 December 2014. Comments will be considered in a final policy release. Details about camp management can be found here.
Approval from the Australian Government may also be required. For more information, see EPBC Act policy statement - Grey-headed Flying-foxes.
Any animal can carry disease. Flying-foxes can carry the Australian bat lyssavirus and Hendra virus; however, transmission to humans is extremely rare.
Australian bat lyssavirus
Australian health authorities suggest that lyssavirus, a virus similar to rabies, poses a low public health risk. Evidence suggests it can only be transmitted to humans in saliva from an infected flying-fox via a penetrating bite or scratch. Coming into contact with flying-fox urine or faeces reportedly poses no risk.
The best prevention methods include:
See the NSW Health infectious diseases fact sheet for more information.
Hendra virus has had much media attention with sporadic cases occurring since the first recorded case in 1994. Previous outbreaks have involved the death of one or more horses, and the virus is believed to have been transmitted from horses to humans.
Flying-foxes are natural 'hosts' of Hendra virus, meaning that they carry the virus but it has little effect on them. It is believed that the virus may be transmitted from flying-foxes to horses via exposure to urine or birthing fluids; although this has not been confirmed.
There is no evidence that Hendra virus can spread directly from bats to humans. Spill-over infection from horses to humans is a very rare event.
The key message is to ensure that horse feed and water troughs are not stored near trees where flying-foxes may feed or roost. Horse owners should use good hygiene practices around horses, be aware of the symptoms of Hendra virus and be vigilant when horses do become sick.
The CSIRO has recently launched a Hendra vaccine for horses, which is now available to all horse owners in Australia and can be administered by accredited vets. The Australian Veterinary Association recommends that all horses in Australia are vaccinated against Hendra.
