Red imported fire ants

​​​Current situ​​ation

Red imported fire ants (RIFA) (Solenopsis invicta) are one of the worst invasive species to reach Australia's shores, and continue to be the target of a national cost-shared eradication program.  


Fire ants were first detected in February 2001 at the Port of Brisbane and in the south western suburbs of Brisbane, South-east Queensland. Spread from the initial Brisbane infestations led to infestations around the greater Brisbane area including Ipswich, Logan and Redlands. Isolated infestations have also been found in the Scenic Rim, Gold Coast and Lockyer Valley areas. Subsequent incursions were detected at Yarwun (2006 and 2013), Brisbane Airport (September 2015) and the Port of Brisbane (May 2016).

The incursions in Queensland are subject to nationally cost-shared eradication programs, while the eradication program for Port of Brisbane (2016) is funded by the Commonwealth and implemented by Queensland.

Fire ants were detected at Port Botany, Sydney in November 2014 and has been subject to a successful nationally cost-shared eradication response.

The NMG has agreed that the Port Botany incursion has been successfully eradicated, with official declaration of eradication expected shortly.

The latest information on the fire ant eradication response at Port Botany can be found on the NSW Department of Primary Industries website.

Reporting detections

Fire ants are a notifiable pest in most Australian states and territories, which means there is a legal obligation to report suspected detections.

Anyone who suspects that they have seen fire ants or any other type of exotic invasive ants should report sightings to the Exotic Plant Pest Hotline on 1800 084 881. This number will put you in contact with your local department of primary industries or agriculture.
