In Australia, the annual precipitation is 700 2 000 mm; In the area where casuarina is cultivated, the annual precipitation is 1 200 1 600 mm, and the high temperature coincides with the rainfall, which is conducive to the high yield of casuarinas.

Red soil and brick red soil developed from basalt on terraces or hilly areas far from the coast can grow even if the soil is not too clayey.
