The common ringtail possum (Pseudocheirus peregrinus, Greek for "false hand" and Latin for "pilgrim" or "alien") is an Australian marsupial. The possum lives in a variety of habitats and eats a variety of leaves of both native and introduced plants, as well as flowers, fruits and sap. It also consumes caecotropes, which are material fermented in the caecum and expelled during the daytime when it is resting in a nest. This behaviour is called caecotrophy and is similar to that seen in rabbits.
The possum carries its young in a pouch, where it develops for 120–130 days before leaving. They are affected by land clearing, which destroys their habitat. The red fox is an introduced invasive species and predator that negatively impacts the possum.
The common ringtail possum is currently classified as one of the two living species in the genus Pseudocheirus; the species of Pseudochirulus and other ringtail genera were formerly also classified in Pseudocheirus. Several subspecies have been described:
Pseudocheirus peregrinus pereginus, the type subspecies based on a collection made at Endeavour River Pseudocheirus peregrinus convolutor, (Eastern ringtail possum or Southeastern... Wikipedia →

Possible
About 20% of wildlife watchers report a Common Ringtail Possum sighting in Cradle Mountain-Lake St Clair National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 9 mammals we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Common Ringtail Possum in Cradle Mountain-Lake St Clair National Park on a given day, against under 5% in May–June, August and October–November, the lowest months. That is one of Cradle Mountain-Lake St Clair National Park's wettest months, with about 230 mm of rain against 95 mm in February.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Common Ringtail Possum sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
7th of 9
Of the 9 parks where we can rate Common Ringtail Possum sightings, Cradle Mountain-Lake St Clair National Park ranks 7th at about 20%. The best odds are in Lamington National Park (Australia, about 40%), Noosa National Park (Australia, about 30%) and Royal National Park (Australia, about 30%). All parks ranked.
Same order: Diprotodontia
The closest relatives of the Common Ringtail Possum that you can see in Cradle Mountain-Lake St Clair National Park (order Diprotodontia, Kangaroos, Possums, Wombats, and Allies) are Common Wombat (over 90%), Red-bellied Pademelon (about 90%) and Red-necked Wallaby (about 80%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Ringtail Possum is recorded against all the mammals logged in Cradle Mountain-Lake St Clair National Park (14 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
