About the plan

Invasive alien tramp ants are a diverse group of species originating from many regions of the globe which arrive at Australia's doorstep through a variety of transport pathways. They share genetic, behavioural, and ecological attributes that influence their probability of entry, establishment and spread, ecological dominance, and high impact.

While their impacts on biodiversity in Australia are not well quantified, many tramp ants have the ability to affect Australia's native biodiversity. Their impacts may be felt directly through predation upon or competition with native animals, or indirectly by modifying habitat structure and altering ecosystem processes. Most tramp ants have multi-sectoral impacts, and can affect plant and animal health, social and cultural values, and human health.

The effective and appropriate management of threats from tramp ants poses a formidable challenge to Australia, testing the continuum of biosecurity, from pre-border surveillance through to pest management. Individual tramp ant species are at varying stages in the invasion process, so the nature and scale of management responses will vary accordingly.

The tramp ant threat abatement plan establishes a national framework to guide and coordinate Australia's response to tramp ants, identifying the research, management, and other actions necessary to ensure the long-term survival of native species and ecological communities affected by tramp ants.

The goal of the plan is to minimise the impact of invasive tramp ants on biodiversity in Australia and its territories by protecting threatened native species and ecological communities, and preventing further species and ecological communities from becoming threatened.

The Department of the Environment and Heritage will convene a national implementation team to assist and advise on the implementation of the plan. The team will include people with expertise in the research and management of tramp ants. It will also include stakeholders such as state and territory agencies.
