The Australian Water Dragon (Intellagama lesueurii), which includes the Eastern Water Dragon (Intellagama lesueurii lesueurii) and the Gippsland Water Dragon (Intellagama lesueurii howittii) subspecies, is an arboreal agamid species native to eastern Australia from Victoria northwards to Queensland.
The two subspecies are generally easy to distinguish.
Adults Intellagama lesueurii lesueurii have a prominent dark stripe behind the eye and typically have a pale, unmarked throat that is sometimes immaculate white in mature males.
Intellagama lesueurii howitti lacks the dark stripe behind the eyes and instead has an orange-yellow streaked throat with darker striping.
Young Intellagama lesueurii lesueurii don't yet have a developed dark stripe behind the eyes (as on the photos).
In addition, Intellagama lesueurii lesueurii occurs along the east coast of Australia from Cooktown in the north down to the New South Wales and Intellagama lesueurii howitti occurs more south in New South Wales down to Victoria.
