The Smooth Newt is also introduced in Australia, most possibly via escapes or illegal release of pets. In 2015 the successfully established population was reported from southeastern Australia. Currently the species is listed as a controlled pest animal, and an invasive species potential cannot be overlooked.
The Smooth Newt is common over much of its native range. The numbers are currently stable.
There are no major threats to the species. Still, some local populations are in decline due to anthropogenic factors that affect the natural feeding an breeding habitats of the species.
