Camphor Laurel (Cinnamomum camphora) is a large evergreen tree that grows up to 20-30 metres tall. The leaves have a glossy, waxy appearance and smell of camphor when crushed by hand. In spring it produces bright green foliage with masses of small white flowers. It produces clusters of black berry-like fruit around one centimetre in diameter.

Camphor Laurel is native to Taiwan, southern Japan, southeast China and Indochina, where it is also cultivated for camphor and timber production. The production and shipment of camphor, in a solid, waxy form, was a major industry in Taiwan prior to and during the Japanese colonial era (1895-1945). It was used medicinally and was also an important ingredient in the production of smokeless gunpowder and celluloid. Primitive stills were set up in the mountainous areas in which the tree is usually found. The wood was chipped; these chips were steamed in a retort, allowing the camphor to crystallize on the inside of a crystallization box, after the vapour had passed through a cooling chamber. It was then scraped off and packed out to government-run factories for processing and sale. Camphor was one of the most lucrative of several important government monopolies under the Japanese.

It has been declared a noxious weed for the entire states of Queensland and New South Wales. Its massive and spreading root systems disrupt urban drainage and sewerage systems and degrade river banks. Its leaves have a very high carbon content, which damages water quality and freshwater fish habitats when they fall into streams and rivers. The camphor content of the leaf litter helps prevent other plants from germinating successfully, helping to ensure the camphor's success against any potentially competing vegetation, and the seeds are attractive to birds and pass intact through the digestive system, ensuring rapid distribution. Camphor laurel invades pastures, and also competes against eucalyptus trees which are the sole food source of koalas, which are endangered in many parts of eastern Australia.
