The Australian Plague Locust Commission (APLC) produces a monthly Locust Bulletin during the seasons of locust activity (spring, summer and autumn). The Bulletin gives regional summaries of the locust situation and weather events of potential significance for locust development. It also provides a forecast of likely developments for the next three months (or from autumn to spring) for the Australian Plague Locust Chortoicetes terminifera, Spur-throated Locust Austracris guttulosa, and Migratory Locust Locusta migratoria.
The spur-throated locust, Austracris guttulosa, is mainly a tropical species and swarms of immature adults form in savannah areas of the Central Highlands and northwest Queensland, in the Northern Territory and northern Western Australia in late autumn and winter. Spur-throated locusts also breed in southern Queensland and the northwest plains and central west of NSW.
The migratory locust, Locusta migratoria, is mainly a pest in the Central Highlands of Queensland where small outbreaks are frequent. Outbreaks also occur in the western Darling Downs and Roma and St George areas in southern Queensland.
The Australian Government is a signatory to arrangements that will provide support from other participating countries during an emergency animal disease outbreak.
Australia's biosecurity system is recognised worldwide as strong, bringing benefits to our economy, our unique environment and our way of life.
Australia remains free of many significant pests and diseases enabling globally competitive and sustainable industries.
