The spotted grass frog or spotted marsh frog (Limnodynastes tasmaniensis) is a terrestrial frog native to Australia. It is distributed throughout all of New South Wales and Victoria, eastern South Australia, the majority of Queensland, and eastern Tasmania. It is also naturalised in Western Australia, having been unintentionally introduced at Kununurra in the 1970s, apparently during the relocation of several hundred transportable homes from Adelaide.
The spotted grass frog was also formerly known as the "Marbled frog" in South Australia, although this common name is also used for Limnodynastes convexiusculus, a species of ground-dwelling frog native to northern and north-eastern Australia, and southern New Guinea.
This frog reaches 45 mm (1.8 in) in length. Its colour ranges from light brown to olive-green, with large, irregular shaped, green or brown spots on its back. Occasionally it will have a thin, pale cream, yellow or bright orange stripe running from snout to vent. There is a raised pale stripe running from below the eye to the base of the arm. The arms and legs are spotted like the back, and the belly is white.

GBIF citizen-science records
It is estimated from how often the Spotted Grass Frog is recorded against all the amphibians logged in Kosciuszko National Park (5 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.
