History and use
The prickly pear was introduced into Australian gardens from South America in the 1830s. It grew quickly and farmers used it as an effective hedge to fence in farmland. The plant's tolerance to drought and the lack of any predators allowed it to spread rapidly. By 1900 it covered over 4 million hectares in Queensland and New South Wales and by 1925, over 24 million hectares were affected. This resulted in the land being useless for agricultural purposes and led to the eventual abandonment of the farms.

Various methods were used in an attempt to control the plant, including the injecting of poisons such as arsenic, common salt and caustic soda. This container is a form of ‘pressure tank’ to hold such poisons. It would have been attached to a poison injecting device. In 1925 the Cactoblastis cactorum insect was introduced into a property at Chinchilla, Qld., and by 1932 the Prickly Pear Land Commission reported that the prickly pear problem had been solved.
