A swarm of locusts covering 1 kilometre of land can contain anywhere from 4 million to 50 million individuals. Locust plagues can occur anywhere in mainland Australia but outbreaks are frequently seen in inland areas of Queensland, New South Wales and South Australia.

Australian Locusts

Australian Locusts
Major outbreaks of locusts occur when a significant amount of rain has fallen and there is a substantial amount of wind. The ability of the locusts to form large communities to eat, make them a fearsome foes for producers. As they are highly mobile creatures, locusts pose a serious risk to all agricultural areas.

Australian locusts feed on grasses and cereal crops although they can also feed on a wide variety of plants including grapevines and trees. The young hoppers can do extensive damage to pastures but as they cannot fly they are limited to the surrounding area. When locusts reach full maturity, they are highly mobile, and can swarm; this is where the most severe damage occurs.

When a locust outbreak occurs the population needs to be controlled as quickly as possible and in the most cost-effective way. The Australian Plague Locust Commission (APLC) manages outbreaks of locust populations. The APLC uses an integrated management process; their main aim is to limit the population of locusts, before they reach a huge numbers.

It is important to report any sightings of locusts, so that the proper management and care of locusts can be taken. You can do this by contacting your local Rural Lands Protection Board, Department of Primary Industries (Agriculture) or the APLC. The APLC can be contacted on 1800 635 962.
