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.

Occasionally it will have a thin, pale cream, yellow or bright orange stripe running from snout to vent.

This is used to froth the water during amplexus to create the floating foamy nest that it lays eggs in, which is roughly the size of a human palm.

The two frogs can be distinguished by a disproportionately long second digit of the inner front toes in the case of L. fletcheri.

The long-thumbed frog also has larger irregular shaped spots on the back and a red/purple eyelid, which is uncommon in L. tasmaniensis.
