The nut which is also sometimes under its original name, Queensland nut, was discovered five thousand years ago by the aborigines. It has been a rediscovery in 1858 by two British botanists who call it Macadamia, in tribute to Dr. John Macadam, a chemist and physician Australian. At the end of the 19th century, some of Queensland nuts were imported to Hawaii in order to cultivate ans sell them .

The Macadamia has now grown in Australia and New Zealand but also in South Africa, Costa Rica, Brazil and California (including San Francisco). There is an small production in Spain and North Africa.

Australia is still the leader with 45% of world production. Australia exported 10 000 tons in 27 countries.
