Kangaroo Island feral cat eradication initiative

Initiative aims

The goal of the Kangaroo Island feral cat eradication initiative is to eradicate feral cats from Kangaroo Island (KI) by 2030.  The initiative is being led by the Department of Environment, Water and Natural Resources (DEWNR) and KI Natural Resources Management Board (the Board), collectively known as Natural Resources Kangaroo Island (NRKI) and the Kangaroo Island Council (Council) and is supported by all levels of government.

The Board formally launched the Kangaroo Island feral cat eradication 2015 -2030 prospectus at the Threatened Species Summit in Melbourne in July 2015.

Nationally important

Kangaroo Island is nationally important for biodiversity conservation, primary production and tourism, with nearly 50% of the native vegetation remaining.  Kangaroo Island is already free from foxes and rabbits.

Kangaroo Island is set to become one of the world's largest inhabited islands free of feral cats under a community-driven, NRKI supported, Australian Government plan to make the island a safe haven for wildlife. Kangaroo Island joins Bruny Island, French Island, Christmas Island and Dirk Hartog Island on the Australian Government's list of five priority islands (announced June 2016) aiming to become feral cat free. 

Feral cat impacts

Feral cats spread livestock diseases (sarcocystis and toxoplasmosis) that impact production and profitability, causing substantial economic cost to the Kangaroo Island sheep industry (approximately $2 million annually).

Feral cat predation is a major threat to the island's valuable and endemic fauna, with up to 50 native animal species at risk including the:

  • endangered southern brown bandicoot (Isoodon obesulus ssp. obesulus)
  • endangered Kangaroo Island dunnart (Sminthopsis aitkeni)
  • endangered Kangaroo Island echidna (Tachyglossus aculeates multiaculeatus)
  • endangered southern emu wren (Stipiturus malachurus).

Three stage initiative

Stage 1. 2015-2018

Trial feral cat control techniques, establish baseline monitoring programs and establish a process for gradual phasing out of all cats.

Stage 2. 2018 - 2021

Eradicate feral cats from the Dudley Peninsula, monitor success of control actions and initiate a gradual phasing out of all cat ownership.

Stage 3. 2021 - 2030

Eradicate feral cats from Kangaroo Island, monitor success of control and continue with the phasing out of all cat ownership.

We invite you to sponsor

Your sponsorship of this ground breaking feral cat eradication initiative, will ensure the protection of our threatened native species and the valuable sheep industry of Kangaroo Island.

Becoming a sponsor in the feral cat eradication initiative offers you the unique opportunity to show your support for the islands threatened fauna and agricultural industry.

Unique opportunity

Kangaroo Island provides a unique opportunity to control and eradicate feral cats across an entire environmental region given its:

  • border security (being an island)
  • supportive local government on domestic cat management
  • community support for both domestic cat management and feral cat eradication
  • long history of feral cat management and research on the island to inform control techniques
  • absence of foxes, wild dogs and rabbits from the island
  • support from key stakeholders who are collaborating with the project to ensure Kangaroo Island is feral cat free by 2030.

Your contribution and the benefits it will bring:

Have you seen a feral cat recently?

A new Kangaroo Island feral cat website and App called ‘Feral Cat Scan’ has just been created to help our community record sightings of feral cats anywhere on the Island. Information you record will help to identify hot-spots for feral cats and identify solutions to the feral cat problem across the Island. Please register your details and login to record feral cat activity in your local area. You can record sightings, impacts (such as predation on native animals) or control activities in Feral Cat Scan. Please visit the website or download the FeralCatScan App.

A feral cat survey has been developed by NRKI and Kangaroo Island Council, to capture the communities views on the project and its aims. If you have not already completed the cat survey, please do so here KI community cat survey.

Joint initiative

This project is a joint initiative of Natural Resources Kangaroo Island (DEWNR and the KI NRM Board) and Kangaroo Island Council in collaboration with Primary Industries and Regions South Australia and partnering with Invasive Animal Cooperative Research Centre and Ecological Horizons.

A workshop, for the five Australian islands prioritised for feral cat eradication under the Australian Government Threatened Species Strategy was conducted on Kangaroo Island in June 2017 to share learnings from current eradication programs. This included successes and challenges, and helped build a network of practitioners for future collaboration and sharing of research. Delegates from an additional six islands (West Island, Tiwi Islands, Phillip Island, Lorde Howe Island, Rakiura/Stewart Island (NZ) and Groote Eylandt) currently undertaking feral animal control and/or research were also invited to attend. Several guest experts delivered presentations about animal welfare, island eradication concepts, the use of toxins and community engagement. Natural Resources Kangaroo Island hosted the workshop, which was supported by the Office of the Threatened Species Commissioner through funding from the Australian Government’s National Landcare Program. Download the workshop report here.

This project is funded by the Australian Government with in-kind support from DEWNR.
