The Australian Plague Locust Commission (APLC)controls locust migrating long distances across STATE BORDERS of NSW, Victoria, SA and Queensland; it is not responsible for the control of locusts in Western Australia. It was established in 1974 to overcome the difficulties encountered when controlling insects that migrate long distances across state borders. It is responsible for control of the Australian plague locust, the spur-throated locust and the migratory locust in those situations where they have the potential to inflict significant damage to agricultural industries in more than one member state. The APLC engages in operations designed to combat outbreaks or potential outbreaks of locusts which in the opinion of the Commission are likely to result in damage to rural industries in another State. Protection of crops is not the responsibility of the Commission although on occasion that may occur as a consequence of controlling a significant band or swarm target. Its objective is to conduct preventative control. Regular field surveys are conducted to assess the current size of locust populations. While locusts may be present over a considerable area during an outbreak, the major part of the population will be concentrated in bands of nymphs (hopper bands) and adult swarms which the APLC must find and control. The APLC is responsible to the Commonwealth Minister for Agriculture, Fisheries and Forestry and to the relevant State Premiers. The APLC is jointly funded by the Commonwealth (50%), New South Wales (32.5%), Victorian (10%), South Australian (5.0%) and Queensland (2.5%) governments.
