Flying-foxes in Eurobodalla
December 2019: The Grey-headed flying-foxes are back in the area after spending the winter further north. There have been around 800 flying-foxes in the camp at Catalina golf course in Batemans Bay for just over a month and 200 now in the Water Gardens with their young. We expect the numbers of flying-foxes in our area to increase over the next few months as they have in previous years.
We will monitor the camps regularly while flying-foxes are present, you can view population monitoring data on this page.
Please report day-time sightings of any flying-fox camps in Eurobodalla.

What is Council doing?
Flying-fox management actions being performed by Eurobodalla Shire Council include:
- developed a shire-wide Eurobodalla Flying-fox Management Plan
- ongoing employment of a dedicated Natural Resources Officer - flying-foxes to facilitate flying-fox management and engagement with the community
- providing relief to residents through subsidised services when conditions require
- undertaking flying-fox dispersal (where necessary and in accordance with approval conditions)
- participating in flying-fox monitoring and research
- maintaining buffer zones on Council land
- ongoing restoration of the Batemans Bay Water Gardens with planting of native species and weed control
- collaborating with other councils, agencies, land managers and community groups
- implementing a communication strategy based on community feedback
- community education, students and adults learning about flying-foxes and other bats.
Assistance for residents
Council provides access to high pressure washers that can be borrowed from Council's Batemans Bay Depot to clean hard surfaces, cars and homes. Residents can contact the Depot on 4472 4035 to arrange borrowing the washers.
Further assistance may be considered by Council if residents are impacted by excessive numbers of flying-foxes.
Cocos palms, which attract foraging flying-foxes, can be removed from private property without the need for Council approval.
Native plants such as Lilli pilli, gum trees and Banksias cannot be removed without Council approval under the Tree Preservation Code. Council will not allow the removal of native trees unless they pose a significant risk to people or infrastructure (such as falling limbs). Contact Council on 4474 1000 for further information.
- For more information on these services, phone our Natural Resource Officer - flying-foxes, Natalie Foster on 4474 7329.

Grey-headed flying-foxes, also called fruit bats, have always had camps in Eurobodalla Shire. Population numbers vary with seasonal migration. Any flying-foxes in the region are likely to forage around residential areas at night wherever there are food sources, regardless of where they have day-time camps.
The CSIRO has developed a methodology to measure national flying-fox populations:
The NSW Office of Environment and Heritage regularly monitored the camp areas at Batemans Bay after the massive influx of flying-foxes in 2016, up until dispersal activities finished at the end of July 2016. See Batemans Bay camps for more information and history. Council now performs this task while flying-foxes are present in the five known camps.
During the monitoring, Council officers assess the population, camp footprint, distance to nearby residents, presence of dependent young and overall health of the flying-foxes. In addition, we monitor the community's concerns and offer advice and assistance where we can.
Regular reports are sent to the Office of Environment and Heritage where they add to the growing body of information which will help us to understand the behaviour and movements of the grey-headed flying-foxes.
Eurobodalla Shire flying-fox camps
There are currently five known camps in Eurobodalla Shire that have been occupied by flying-foxes consistently. These have been monitored regularly since 2016 by Council officers. See the graph below for a summary of all camp populations between July 2018 and July 2019.
Each camp is summarised separately in terms of their context, history, population, ecological values and latest information. Click on the camp (below) that you are interested in for more information. For a full assessment of all camps known in the Eurobodalla Shire, go to Section 6 of:
The proximity of the camps to residences, towns and sensitive receptors (hospitals, schools, etc.) increases the likelihood for conflict. Council acknowledges there may be other unknown camps in the Eurobodalla Shire area at any time but while they remain unknown and trigger no cause for conflict, they do not require active management by council.
Management options for each camp, are outlined in the Eurobodalla Flying-fox Management Plan, Section 7 in accordance with the legislative framework (Section 2) and Council’s management framework (Section 5). From north to south these camps are:
Batemans Bay Water Gardens and Catalina camps
There are two flying-fox camps in Batemans Bay at:
- the Water Gardens near Batemans Bay township
- northern Catalina on the Club Catalina golf course.
Water Gardens camp
The Water Gardens is a six-hectare wetland park close to the Batemans Bay town centre. The Gardens is Council managed land, with the area occupied by flying-foxes also extending onto private land.
Site characteristics and history
The Water Gardens site is a natural drainage area that was once used for stock grazing. The site vegetation is Swamp Oak Floodplain Forest, which is listed in NSW as an Endangered Ecological Community (EEC). The land is zoned for Environmental Conservation.
In 1989, the Batemans Bay Historical Society requested Council redevelop the site into a town park.
The Water Gardens opened in 1999, managed by a community-driven committee.
By 2012, Council had resumed management of the site. The regrowing vegetation was bordering many residential properties surrounding the park.
Flying foxes at the Water Gardens
Grey-headed flying-foxes have been officially recorded at the Water Gardens since 2012. Though there are some reports of them occupying the site in small numbers before 2012.
In 2013 the camp comprised more than 10,000 individuals and a bit over 20,000 in 2014.
In 2015, in response to this increase, Council developed the Water Gardens Grey-headed Flying-fox Management Plan 2015. This plan prioritised management options to reduce impacts on residents and businesses. Options included removing the overgrown vegetation to re-instate buffers between residences.
In mid-2016, a mass-flowering of spotted gum and red bloodwood occurred in the region’s forests. This flowering attracted hundreds of thousands of flying-foxes to Batemans Bay.
In response, Council extended the buffer zones to residences. The buffer zones are now regularly maintained by Council and Batemans Bay Local Aboriginal Land Council.
Other maintenance work included:
- weed control
- rubbish removal
- infrastructure maintenance
- planting and mulching native shrubs and grasses.
The Green Army installed wildlife cameras to monitor native and feral animals and nest boxes in the tree canopy for birds and gliders.
Council installed a water pump and canopy sprinklers to discourage flying-foxes from roosting in the vegetation nearest to houses.
Unfortunately, some people use the Water Gardens to dispose of rubbish or dump shopping trolleys. Council rangers issue fines for littering, so if you see somebody doing the wrong thing, please report it to Council on 4474 1000.

Regular monitoring began after June 2016 dispersal.
Northern Catalina camp
The camp on the Club Catalina golf course is on land zoned as Environmental Conservation, along Hanging Rock Creek in Batemans Bay. The vegetation is Swamp Sclerophyll Forest on Coastal Floodplain or Coastal Swamp Oak Forest which is listed as an endangered ecological community by the Australian Government under the Environment Protection and Conservation Act 1999.
Flying foxes at Catalina
Council has monitored the camp since November 2012. Flying-foxes irregularly occupy this camp and were known to be present in 2013, 2016, 2017, 2018 and 2019.
The population at this camp has always been less than 5000 except in May 2016 when more than 120,000 flying-foxes used the existing camp and spilled over into the surrounding residential and forest areas.
At its largest, the Catalina camp covered 18.74 hectare. The persistent flying-fox camp is concentrated on the central area of vegetation near the waterways.

What happened in 2016?
In 2016 more than 270,000 Grey-headed flying-foxes congregated within Batemans Bay. This was approximately 40% of the entire species population counted in May 2016.
The flying-foxes were attracted by a mass flowering event of spotted gum (Corymbia maculata) and red bloodwood (Corymbia gummifera).
Spotted gums and red bloodwoods tend to have flowering events every four to seven years. Spotted gums tend to flower from late autumn through winter and red bloodwoods flower summer through autumn. We don’t know why the conditions in 2016 resulted in simultaneous flowering of the two species.
During this time, flying-foxes occupied the Water Gardens and Catalina camps, and extended into vegetation in residential areas surrounding the camps. This caused significant conflict with residents, many of whom had not been impacted by flying-foxes before.

Dispersal and camp-management actions
Council requested approval to carry out dispersal activities and the Minister for the Environment granted a National Interest Exemption under s158 of the Environment Protection and Biodiversity Conservation Act 1999 to allow dispersal of the flying-foxes and more severe vegetation management at the camps. This exemption was conditional on the development of a Conservation Agreement, which led to development of the Eurobodalla Flying-fox Management Plan.
The Batemans Bay Flying-fox Camp Dispersal Plan 2016-2019 was developed in 2016. In June and July 2016 Council carried out approved flying-fox dispersal activities in accordance with conditions set by the Commonwealth Environment Minister’s National Interest Exemption and the NSW Flying-fox Camp Management Policy.
Flying fox numbers had already begun to decrease naturally by the time dispersal activities began, so the dispersal was successful in reducing the remaining populations from undesirable locations.
- removed 5.3 hectares of vegetation from the Water Gardens and Catalina areas to provide buffers for residents.
- removed Cocos palms to reduce disturbance from night time foraging and mess from faecal drop.
- carried out weed removal, mulching and planted native shrubs and grasses to restore the appearance and condition of the Water Gardens.
In accordance with the EPBC Act Referral Guideline, no additional vegetation removal is possible at the Water Gardens without referral to the Australian Environment Minister.
Council now has a five-year Threatened Species Licence to manage for flying-fox camp dispersal in Batemans Bay. The decision to disperse will be made in line with the management framework in the current Eurobodalla Flying-fox Management Plan.

Moruya Heads camp
The Moruya Heads camp is located on private land zoned as Environmental Conservation. The vegetation at this camp is mapped as Swamp oak floodplain forest, an Ecologically Endangered Community (EEC).
Flying-foxes occasionally occupy the camp at Moruya Heads. The residences are not as many or as close as some of the other Eurobodalla Shire camps.
In 2013, the National Flying-fox Monitoring Program recorded that 10,000 flying-foxes stayed briefly in February, and 2000 camped there in 2015 at the same time of year.
Council has monitored this camp since 2016 with little no or activity recorded until 2019, when an influx of around 13,000 grey-headed flying-foxes camped there briefly in the early part of the year.

Tuross Heads camp
The Tuross Head camp is located on a parcel of vacant privately-owned land zoned as Environmental Living and Low Density Residential. The vacant land is on Hector McWilliam Drive, with residences lining the other side of the road.
The average known camp extent is approximately 1,500 m2. The vegetation at this camp is mapped as Yellow stringybark – coast grey box shrubby open forest on coastal ranges, south east corner.
Flying-foxes have occupied this camp annually since it was identified in 2017. This camp was monitored as part of the National Flying-fox Monitoring Program with only 100 flying-foxes counted in 2017.
Council has monitored this camp regularly since 2017, with maximum numbers of 500 in 2018 and creeping up to 3,000 during April and May 2019.
Population at Tuross Head camp 2016 to 2019
The Narooma camp is on public land zoned as Environmental Conservation, and the average known camp extent covers around 2.8 hectares. Camp vegetation is mapped as Lilly pilly – sassafras, warm temperate rainforest in moist sheltered gullies, Sydney basin and south east corner, which is an Ecologically Endangered Community.
The camp is located away from urban areas and has not been of concern to close residents.
This irregularly occupied camp was monitored as part of the National Flying-fox Monitoring Program in February and May 2013, and December 2017 with no records of flying-foxes recorded. Council has monitored this camp since 2016 with flying-fox numbers equal to or below 400 in the autumn of 2017 and 2018, and creeping up to 3,000 during the autumn months of 2019.
