State government officers from the Department of Agriculture and Fisheries will begin an on-the-ground assessment of the growing threat of Australian plague locusts in the Goondiwindi region tomorrow.

Swarms of the agricultural pest have been spotted in the region for the first time in years, with La Nina's wet conditions inviting them into properties.

Goondiwindi Mayor Lawrence Springborg said the council is urging locals to be aware of the outbreak and report any sightings so biosecurity teams can provide more accurate mapping.

"We're encouraging people to report sightings online, so we can hand that information over," Cr Springborg said.

"We (council) know there is an issue, we are just not sure at this stage the extent of the problem."

Cr Springborg said that because locusts are rare in the region, there has been a breakdown in communications between council and the government about how to respond to the crop-eating pest.

"Council's role is limited, we can only encourage people to spray and report," he said.

"We need the involvement of DAF and Biosecurity Queensland to understand what's going on and then be able to manage it.

"The response probably needed to be better than what it has been, but we have not dealt with a situation like this in the area for a very long time. Now we need to learn from it."

Cr Springborg said there was a growing concern that the locusts' breeding cycle will begin to align with winter weather.

"We've possibly got another two breeding cycles before we get the cooler weather. The locusts could lay again and bring even more damage into spring when winter crops begin to go through a significant growth spurt."

Australian Plague Locust Commission director Chris Adriaansen said the situation in Goondiwindi is still in patches and there has not been widespread coverage of the area.

"With the patchiness, landholders should implement whatever control they believe is appropriate," he said.

Mr Adriaansen said that wet weather and strong winds created the population.

"This is not a common occurrence in the Goondiwindi area, what preceded it was a scattered population of locusts across southern Queensland," he said.

"Storms in late November and December aggregated those locusts into the Goondiwindi area.

"Those relocated grasshoppers laid eggs and it's those eggs that we're starting to see at the moment."
