Allocasuarina thalassoscopica is a shrub growing to about 1 m high, rarely to 2.5 m, similar to A. emuina (Wilson & Johnson 1989).

The species is restricted to Mt Coolum on the Sunshine Coast in south-eastern Qld and known from only a single site that covers about 8.2 ha. It is a common species at the site with an estimated population of around 21 000 plants. There is no evidence to suggest that this species has had a wider distribution historically than it has currently (Halford 1993c).

In the late spring of 1994, a hot wildfire swept over Mt Coolum burning the whole population. Regeneration from perennial rootstocks and seedlings was observed in 1995. However, to what degree the population recovered is unknown (Halford, D. 2000a, pers. comm.).

Difficulty has been encountered in distinguishing between A. thalassoscopica and the closely related species A. emuina. Characters used for distinguishing these species, such as the distance between branchlet joints and anther length, were found to overlap. More investigations are required to clarify the status of these species (Halford 1993b). Until then, A. thalassoscopica remains the accepted name for this taxon (Australian National Botanic Gardens 2004a).

Mt Coolum is an isolated tertiary trachyte intrusion rising to 207 m asl. The species is restricted to the low closed heathland community that occurs on the upper slopes at an altitude of 150-200 m. The slopes are gently to moderately inclined with an easterly, southerly to south-westerly aspect and are exposed to the prevailing winds.

The heathland varies considerably in density and is particularly floristically diverse. Common species recorded at the sites include Acacia hubbardiana, Banksia oblongifolia, Hakea actites, Leptospermum microcarpum, Melaleuca nodosa and Xanthorrhoea latifolia ssp. latifolia. Soils are shallow with a high percentage of substrate outcropping, greyish brown in colour, heavy textured and have a neutral to weak acidic reaction (Halford 1993c). For a more detailed description of habitat, see Batianoff et al. (1985).

Flowering recorded from late May to mid to late July. Plants are unisexual, although some male plants can occasionally produce a small number of female flowers and set small quantities of viable seed (Halford 1993c).

Seeds are released from cones only with the death of the parent plant or of the branch supporting the fruit. Seeds have flat papery wings that would assist dispersal by wind and show no form of germination dormancy once released from the protective fruits (Halford 1993c).

Capable of regenerating from rootstock (Halford, D. 2000a, pers. comm.).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
