The Big Macadamia in Knockrow celebrates Australia's gift to the world of gourmet nuts - the macadamia. This massive sculpture captures the smooth, round perfection of the macadamia nut, which originated in the rainforests of Queensland and NSW before being cultivated commercially and spreading across the globe. The Big Macadamia sits at Macadamia Castle, an attraction that combines nut farming education with a wildlife park. The macadamia is the only Australian native plant to become a significant food crop, now grown commercially in Hawaii, South Africa, and beyond, though the Northern Rivers region of NSW remains one of the world's premier growing areas.

History
The Big Macadamia was erected around 2000 as part of Macadamia Castle, which combines macadamia farming heritage with wildlife tourism. Macadamias are native to the rainforests of the Northern Rivers and Southeast Queensland, first cultivated commercially in the 1880s. Hawaii actually developed the commercial macadamia industry using Australian nuts, but today Australia is once again the world's largest producer.
