It is found from central Queensland south to southern New South Wales. It has become naturalised in the Everglades in Florida where it is considered a weed. |

Wood - tough. Used for axe handles etc, it is said to be better than hickory (Carya spp) for this purpose; The brownish timber is nicely marked and is used for fencing rails, shingles, salt water pilings, poles, charcoal and fuel; Casuarina spp. have very dense wood, with a specific gravity of 0.8 - 1.2, and a calorific value of ca 5,000 kcal/kg; The wood splits easily, and burns slowly with little smoke or ash; It also can be burned when green, an important advantage in fuel short areas; From their fourth year, trees shed about 4 tons cones/year. These, too, make good pellet-sized fuel (NAS, 1983e); | | Vegetative Spread Rate [2] | Rapid | | | Flower Color [2] | Red | | Foliage Color [2] | Green | | Fruit Color [2] | Brown | | | Height [3] | 59 feet (18 m) | | Width [1] | 41 feet (12.6 m) | | | Hardiness Zone Minimum [1] | USDA Zone: 9 Low Temperature: 20 F° (-6.7 C°) → 30 F° (-1.1 C°) | | Hardiness Zone Maximum [1] | USDA Zone: 11 Low Temperature: 40 F° (4.4 C°) → 50 F° (10 C°) | | Light Preference [2] | Full Sun | | Soil Acidity [2] | Neutral | | Soil Fertility [2] | Infertile | | Water Use [1] | Moderate to Low |
