The hard wood and rich texture makes sheoak wood popular among wood-turners. Sheoak wood is also regarded as an excellent firewood as it burns with very little ash.Because of its ability to grow and develop extensive root systems in very poor or sandy soils, and to completely cover the ground with its "needles", it is often used to stabilise soils in erosion prone areas, or on sand dunes. Sheoak is also used as an ornamental shrub, although for this purpose the mat of "needles" may become a nuisance and must be carefully considered.

Allocasuarina huegeliana, commonly known as rock sheoak or sighing sheoak, is a tree in the family Casuarinaceae. Endemic to Western Australia, it occurs throughout the Wheatbelt. It is now especially common on road verges, where it sometimes forms thickets.

Rock Sheoak was first collected on Mount Brown near York in 1840 by Johann Priess. The specific name huegeliana honours the Austrian naturalist Baron von Huegel. The common name "rock sheoak" refers to its habitat, which often contains granite rocks. The alternative common name "sighing sheoak" alludes to the sound of the wind in the foliage.
