Lesueur's frog is associated with rocky streams and creeks in coastal heath forests, montane areas, and rainforests. Males make a soft, purring call from beside creeks or from pools on the edges of streams during spring, summer, and autumn. Breeding occurs mostly after rain. An average of about 1630 eggs are laid in single clump loosely attached to bedrock in streams. The eggs are normally laid in still pools of streams. Hatching occurs up to a week after laying. Tadpoles reach about 4.5 cm (1.8 in), and are golden brown.
Metamorphosis occurs during summer and autumn, about 50–60 days after laying. Metamorph frogs are small, about 1.4 cm (0.6 in) and resemble the adult, but the dark stripe on the head is not very prominent. In 2004, this species was divided into three separate species, with the stony creek frog north of Sydney and
Rhyaconastes jungguy in northern
Queensland. ==References==
