Corella Management Program

Introduced Corellas are becoming an increasing problem on the lower Swan Coastal Plain, including the Bunbury area. Little Corellas (Cacatua sanguinea sanguinea) and Eastern Long-billed Corellas (Cacatua tenuirostris) are both invasive species known to be destructive, noisy, and they out-compete local native species for food and roosting habitat e.g. Western Ringtail Possum and Black Cockatoo.

The damage caused by the corellas is seasonal and tends to occur from late October through to July depending on the season. It is not uncommon to find flocks of between 200 to 500 birds within the city during this time, impacting infrastructure, the environment and community.

Little Corellas are a Category 3 Declared Pest under the WA Biosecurity and Agriculture Management Act 2007 and land holders (City of Bunbury) are required to undertake measures to reduce their impact.

Get involved to support Little Corella Management

The City is seeking your observations of corella flock movements to identify where and how the community is impacted by the declared pest in Bunbury. We’re also interested in your views on Little Corella management.

Please take a few minutes to let us know more about your experience with Little Corellas via the sentiment poll below or use the interactive map to register flock sightings and if applicable, please leave a comment describing any associated impacts.

Your feedback will be used to:

  • Better understand impacts and problem areas.
  • Identify roosting locations and potential future control sites to support management actions.
  • Support the City’s approach to management and provision of community advice on deterrence of corellas on private property.

Pin your observations on the Interactive Map

  • Within the City of Bunbury (Bunbury, East Bunbury, Vittoria, Pelican Point, South Bunbury, Carey Park, Glen Iris, Picton, Withers, Usher, College Grove, Davenport)

    Let us know where you have seen flocks of Little Corellas gathering to feed, roost, or play. Please let us know more about your observations or nuisance impacts you may be experiencing.

Large flocks of corellas and other cockatoos can be a nuisance due to the large amount of noise when congregated at feed and roost sites. People living nearby experience significant noise disturbance with impacts to their sleep and wellbeing. Corellas also cause damage to local sports fields and parks when digging for bulbsand roots, and damage infrastructure e.g.chewing through cables, and trees by branch trimming and biting behaviours when roosting.

The City’s Little Corella management strategy employs a combination of existing methods and investigates new techniques that have not yet been trialledwithin the city. Using a variety of techniques is necessary to address the adaptability of corellas to control mechanisms.
