Experts will continue to monitor the current locust populations across NSW.

Small increases in numbers were noted in a December survey, with some localised high-density movement around Girilambone and Nyngan.

High rainfall in some areas before Christmas meant that the ability to survey the inland regions were limited, though the Australian Plague Locust Commission found a small low-density swarm in the Girilambone-Nyngan areas with some numerous-density adults detected in other parts of the Central West district.

The Collie-Quambone-Coonamble areas were also noted to have activity present (as pictured below).

Most habitats remained unfavourable for locust breeding during December, with expected growth in populations in March 2025.

A spokesperson for NSW Farmers has urged regional communities to be vigilant in monitoring the sightings of locusts over the coming months. 

“Locusts can cause extensive damage to crops and pastures, so it’s important we all monitor for these pests on a regular basis,” they said.

“Farmers need to keep a close eye out for signs of locusts in crops and pastures, and any suspected locust activity can be reported to your Local Land Services Biosecurity Officer.

“Vigilance is key when it comes to protecting our regions and businesses against locusts this year.”
