Saltwater paperbark is found near saline or brackish water, with the Swan estuary its most northern occurrence. It has a gnarled appearance, growing up to 7 m tall but often smaller. Its bark is whiter than other Perth paperbarks. It’s small dull green leaves form in two opposite pairs, and the small woody fruits look star-shaped from above. Flowers are produced in spring.
