A variety of interesting vegetation community types is present on the park. Fertile basalt-derived soils support complex notophyll vineforest. Lowland rainforest of this type has been extensively cleared with less than 10% remaining. It has been thus classified as an endangered ecosystem.

The rainforest also supports threatened plant species listed under the Nature Conservation (Wildlife) Regulation 1994 including the following 7 featured in these paintings.

The vulnerable Cryptocarya foetida, Stinking Cryptocarya The species is named from the offensive odour of the small creamy flowers, which are borne in small clusters. The purplish to black, fleshy, globular fruits are about 1 cm in diameter and enclose a single round seed.

The endangered Randia moorei, Spiny Gardenia Flowers are small and white, with a strong sweet smell, and develop into round yellow to orange berries which eventually turn black.

Pararistolochia praevenosa, host vine for the endangered Richmond Birdwing butterfly Ornithoptera richmondia occurs in the rainforest and this beautiful butterfly is on the park.

Endiandra hayesii; Rusty Rose Walnut, Velvet Laurel The dull, hairy leaves have a closely-veined appearance. Flowers are small, white to pale green, and are held in small clusters. The fleshy fruits are egg-shaped, and are shiny purplish-black when ripe.

Macadamia integrifolia, Macadamia Nut, Queensland Nut Tree, Smooth-shelled Macadamia, Bush Nut, Nut Oak This species produces cream or creamy-white flowers that have been recorded in January, March and June to November. Flowers occur on the end of 30 cm long racemes. Fruit is a hard brown spherical nut encased in a green leathery outer shell.
Arrow-head Vine is a tall woody climber. The triangular leaves with broadly notched bases give the plant its common name, though leaf-shape varies through to oval. The leaves are thick, stiff, glossy, Male and female flowers are borne on separate plants, and are small and inconspicuous in long branched clusters.

A pandanus grove of Pandanus tectorius var. pedunculatus is present on the coastline. These trees with their distinctive appearance are a familiar aspect of Queensland’s coastal landscape. Over the last two to three years these communities have become vulnerable due to attack by the insect Jamella australiae. Native to north Queensland, the insect may have been introduced in nursery grown pandanus from that part of the state.
