Allocasuarina thalassoscopica was first described in 1989 by Lawrie Johnson in the Flora of Australia.{{cite web|title=Allocasuarina thalassoscopica|url= https://id.biodiversity.org.au/instance/apni/744529|publisher=APNI|access-date=15 August 2023}} The specific epithet, (thalassoscopica) means "sea-watcher", referring to its situation on a mountain slope, facing the sea.

This she-oak forms a dense, low, closed heath on the windswept south-facing upper slopes of Mount Coolum and along the coast from Noosa Heads in south-east Queensland to Diamond Beach in northern New South Wales.

Allocasuarina thalassoscopica is listed as "endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999,{{cite web |title=Approved Conservation Advice for Allocasuarina thalassoscopica |url=https://www.environment.gov.au/biodiversity/threatened/species/pubs/21927-conservation-advice.pdf |publisher=Australian Government Department of Climate Change, Energy, the Environment and Water |access-date=15 August 2023}} and the Queensland Government Nature Conservation Act 1992.{{cite web |title=Species profile—Allocasuarina thalassoscopica (Mt.
