To which taxonomic order do both Australian and Asian Water Dragons belong?

Squamata

Both the Australian Water Dragon (genus *Intellagama*) and the Asian Water Dragon (genus *Physignathus*) are classified under the Order Squamata. This order is a massive grouping within the Class Reptilia, encompassing all known lizards and snakes worldwide. While they share this high-level grouping, indicating fundamental similarities as scaled vertebrates, their subsequent placement within the Suborder Iguania and their differing genera (*Intellagama* vs. *Physignathus*) reflect significant evolutionary divergence since their split. Being in the same order signifies shared ancestry tracing back to the common ancestors of scaled reptiles, confirming their fundamental relationship as squamates before the finer branches of classification separate them.
