The macadamia nut is the most famous bush tucker. This fruit of a Queensland walnut tree has been harvested for over 5000 years by the Aborigines but was rebaptised "macadamia" by two English botanists in the middle of the nineteenth century. Since then, this species has been exported to many countries - in particular, South Africa, Costa Rica and Brazil - but Australia still maintains 45% of world production. The kernel is enclosed in a smooth, brown, very hard shell, which is itself protected by a fleshy envelope, the husk. If you'd like to visit a plantation, go for preference between April and September (harvesting season) .
