Two naturalised populations are known outside of its native range: a population successfully established on Guam around 1968, and breeding populations have established in multiple suburbs of Melbourne, Victoria.

GBIF citizen-science records
It is estimated from how often the Eastern Dwarf Treefrog is recorded against all the amphibians logged in Blue Mountains National Park (10 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.
