The striped marsh frog or brown-striped frog (Limnodynastes peronii) is a predominantly aquatic frog native to coastal Eastern Australia. It is a common species in urban habitats. The striped marsh frog was described by French naturalists André Marie Constant Duméril and Gabriel Bibron in 1841.
Females may reach a length of 75 millimetres (3.0 in) and males 70 millimetres (2.8 in). They are a shade of brown on the dorsal surface. This colour can be light or dark; they can also be a red-brown on the dorsal surface. There are distinct darker stripes running down the frogs back (giving this species its name), there is normally a paler mid-dorsal stripe running down the back. There is a black "mask" that runs from the nostril, through the eye and down to the shoulder. This "mask" is followed by a thick light golden line that runs underneath the "mask" and terminates at the end of the mouth. Breeding males develop thick arms, these are used in "wrestling" matches with other frogs, the throat of males is yellow in colour. The belly is white.
It is distributed from the southern parts of the Cape York Peninsula in North Queensland... Wikipedia →

Possible
About 30% of wildlife watchers report a Striped Marsh Frog sighting in Blue Mountains National Park on a given day, based on 106 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 12 amphibians 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.
January and February
In those months about 40% of wildlife watchers report a Striped Marsh Frog in Blue Mountains National Park on a given day, against under 5% in August, the lowest month. Those are among Blue Mountains National Park's wettest months, with about 130 mm of rain a month against 40 mm in May.
Between 5 and 8 pm
Across all the parks we cover, that three-hour window holds the most Striped Marsh Frog sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 7 parks where we can rate Striped Marsh Frog sightings, Blue Mountains National Park ranks 2nd at about 30%, level with the leaders once rounded. The best odds are in Booderee National Park (Australia, about 30%).
GBIF citizen-science records
It is estimated from how often the Striped Marsh Frog is recorded against all the amphibians logged in Blue Mountains National Park (106 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.
