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 20% of wildlife watchers report a Striped Marsh Frog sighting in Sydney on a given day, based on 579 verified sightings from GBIF citizen-science data. It is the 2nd most-seen of the 8 amphibians we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
January–February and April
In those months about 30% of wildlife watchers report a Striped Marsh Frog in Sydney on a given day, against about 10% in June and July, the lowest months.
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.
Yes
Of the 3 cities where we can rate Striped Marsh Frog sightings, Sydney has the highest daily chance: about 20%. Next come Brisbane (Australia, about 20%) and Melbourne (Australia, about 20%).
Same order: Anura
The closest relatives of the Striped Marsh Frog that you can see in Sydney (order Anura, Frogs and Toads) are Peron's Tree Frog (about 30%), Eastern Dwarf Treefrog (about 20%) and Common Eastern Froglet (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Striped Marsh Frog is recorded against all the amphibians logged in Sydney (579 verified sightings), 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.
