Cassinia thinicola commonly known as sand everlasting,[2] is a species of flowering plant in the family Asteraceae and is endemic to coastal New South Wales.

It is a compact shrub with hairy young stems, needle-shaped to slightly flattened leaves, and corymbs of up to 150 flower heads.

The flower heads are about 4 mm (0.16 in) long with five to seven cream-coloured florets surrounded by papery involucral bracts in four or five whorls.

[3] Cassinia thinicola was first formally described in 2004 by Anthony Edward Orchard in Australian Systematic Botany from specimens collected at Caves Beach in 2004.

[5] Cassinia thinicola grows on old sand dunes and cliffs near the coast between Berowra and Forster in New South Wales.
