The Wotjulum frog (Litoria watjulumensis) is a species of frog in the subfamily Pelodryadinae. Its habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, subtropical or tropical swamps, rivers, intermittent rivers, swamps, freshwater lakes, freshwater marshes, intermittent freshwater marshes, and rocky areas.
Litoria watjulumensis was named for Watjulum Mission in the north of Western Australia, sometimes spelled 'wotjulum'. This has led to variants in the common names and the specific epithet, repeating the spelling of Tyler's publication as Hyla wotjulumensis. The common names include Watjulum or Wotjulum frog, Watjulum Mission tree frog, and giant or large rocket frog.
The publication of the species was based on a type collection by Copland. The collection, of 29 specimens at the Western Australian Museum, was reassigned as three syntypes; for this species, Litoria coplandi, and Litoria peronii. The type for Litoria watjulumensis was collected near Watjulum mission "close to Yampi Sound, north of King Sound". Wikipedia →

Likely
About 40% of wildlife watchers report a Watjulum Frog sighting in Nitmiluk National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
April and May
In those months about 60% of wildlife watchers report a Watjulum Frog in Nitmiluk National Park on a given day, against under 5% in August, the lowest month. Those are among Nitmiluk National Park's driest months, with about 25 mm of rain a month against 270 mm in January.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Watjulum Frog sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 3 parks where we can rate Watjulum Frog sightings, Nitmiluk National Park has the highest daily chance: about 40%. Next come Litchfield National Park (Australia, about 30%) and Kakadu National Park (Australia, about 30%).
GBIF citizen-science records
It is estimated from how often the Watjulum Frog is recorded against all the amphibians logged in Nitmiluk National Park (15 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.
