Hi confused, these geckos are two separate species. The Thick-tailed Gecko (Underwoodisaurus milii) is found across southern Australia, including Victoria. The Knob-tailed Gecko (Nephrurus amyae) lives in central Australia and doesn't venture into Victoria.

Thick-tailed Geckos were previously classified as Nephrurus milii, showing their close relationship to Knob-tailed Geckos, but their classification was reviewed and they have since been found to be taxonomically more distinct.
