Copland's rock frog or the saxicoline tree frog (Litoria coplandi) is a species of frog in the subfamily Pelodryadinae. It is endemic to Australia, in a range extending from the Kimberley region of Western Australia to Arnhem Land and a record in the north of Queensland.
Its natural habitats are subtropical or tropical dry shrubland, subtropical or tropical dry lowland grassland, intermittent rivers, and rocky areas. The IUCN Red list gives the conservation status of least concern, and notes the population trend as stable.
The publication of the species, by Tyler in 1968, was based on his study of a type collection by Copland. The collection, 29 specimens at the Western Australian Museum, was reassigned as three syntypes; for this species, Litoria watjulumensis, and Litoria peronii. The holotype for L. coplandi was collected at Inverway Station in the Northern Territory. Wikipedia →

Possible
About 20% of wildlife watchers report a Copland's Rock Frog sighting in Kakadu National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 12 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
November
In that month about 40% of wildlife watchers report a Copland's Rock Frog in Kakadu National Park on a given day, against under 5% in August, October and December–April, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Copland's Rock Frog sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
2nd of 2
Of the 2 parks where we can rate Copland's Rock Frog sightings, Kakadu National Park ranks 2nd at about 20%. The best odds are in Litchfield National Park (Australia, about 30%).
Same genus: Litoria
The closest relatives of the Copland's Rock Frog that you can see in Kakadu National Park (genus Litoria) are Watjulum Frog (about 30%), Australian Rocket Frog (about 20%) and Desert Tree Frog (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Copland's Rock Frog is recorded against all the amphibians logged in Kakadu National Park (11 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.
