Sea Acres National Park

Native animals

The park provides valuable habitat for a diversity of wildlife. Several fauna surveys of limited scope have been done but no full survey of the native fauna has been undertaken.

Species recorded to date are 21 mammal species, over 100 bird species, 17 reptile species, 6 frog species and numerous invertebrates, including a rare freshwater snail known only at this location.

Thirteen fauna species observed in the reserve are listed as vulnerable under the Threatened Species Conservation Act 1995: osprey, barred cuckoo-shrike, wompoo fruit-dove, rose-crowned fruit-dove, sooty oystercatcher, scarlet robin, spotted tail quoll, yellow bellied sheathtail bat, koala, grey headed flying fox, little bentwing bat, eastern bentwing bat, and the greater broad-nosed bat.

Other rare species include the brahminy kite, frequently found on the headlands, the white bellied sea eagle and the emerald dove that lives on the forest floor. The toe nipper, a small yabby found only here and in the drains of the lower Macleay River. The papuexul snail, once found around Brisbane was thought to be extinct until found here in 1995.

There is an unknown number of insect species. The rare regent skipper butterfly has been found within the park.

Reptiles that are periodically seen from the rainforest boardwalk include the lace monitor or goanna, the land mullet and the diamond python.

Fauna plays an important role in rainforest ecology, by assisting with pollination of flowers, spreading seeds to enable forest regeneration and by aiding the decomposition of organic matter to release trapped energy and nutrients. Many species are active at night and are rarely seen during the day.


Mammals found in the reserve include the koala, red-necked wallaby, swamp wallaby, grey-headed flying fox, three species of microbats, brown antechinus or marsupial mouse, bush rat, brushtail possum and ringtail possum. Koalas occasionally enter the reserve to feed on the eucalypts along the western boundary and can sometimes be seen in the subtropical rainforest.

Grey-headed flying fox sometimes visit, helping the rich ecosystem by pollinating the many rainforest fruiting trees and dispersing rainforest seed to other areas up to 40 km away.


The rainforest provides significant seasonal food supply for migratory and sedentary fruit-eating birds. The rose-crowned fruit-dove has been recorded breeding in the reserve, and a number of favoured food tree species of the topknot pigeon are found here.

The distinctive call of the green catbird may be heard or a yellow robin, the Eastern whipbird or the spectacled monarch may be glimpsed through the dense foliage. Brush turkey are some of the most visible birds in the reserve and can often be seen foraging on the forest floor searching for organisms in the rich layer of leaf litter. With their strong legs and claws they move wood and rocks to catch the small animals hiding underneath. The males build large mounds of leaf litter for egg incubation.
