When Lismore was invaded by the pesky Yellow Crazy Ants (YCA) last year, experimental water crystal baits and a retrained koala odour detection dog were two of the innovative techniques used to eradicate them.

The successful experimental techniques have brought recognition to the North Coast Local Land Services in partnership with the Department of Primary Industries at this year’s Australian Biosecurity Awards.

The Yellow Crazy Ant response was the recipient in the Government Category which recognises individuals, groups or organisations within the government that have demonstrated a significant contribution to maintaining Australia’s biosecurity integrity.

North Coast Local Land Service general manager Louise Orr said the award was a credit to everyone involved, including many dedicated and determined community members. 

“This award recognises the enormous effort made by our community, including staff. Together, we all play a vital role in helping to protect against pests, and support biosecurity in our community,” she said. 

“YCA are highly destructive environmental pests that can impact on human amenity, agricultural production and the horticultural industry."

When YCA were detected on the NSW north coast, a well-executed and coordinated response plan helped control and eradicate this significant invasive pest.

Following a report from a member of the public, established infestations were identified at Lismore and Terania Creek. 

The detection was especially significant, given Terania Creek is the location of a rainforest protection campaign that helped shape the modern Australian environmental movement. 

Various innovative approaches were used, including experimental water crystal baits the use of a retrained koala odour detection dog to detect YCA. 

“The response plan was a success, with proof of freedom confirmed at both sites and statistical modelling indicating that it is highly unlikely that other infestations remain undetected nearby,” Louise said.

“The response plan was widely promoted, with significant local engagement undertaken by Local Land Services. 

“As a result, the aim to eradicate Yellow Crazy Ants gained excellent and broad support from the people of Lismore and Terania Creek.”

North Coast Local Land Services and NSW DPI were nominated by Invasive Species Council chief executive, Andrew Cox.
