Our Ozzy Goanna was wrongly named after Iguanas, a Spanish word which might have been adapted from and Indian term for this group of distinctive lizards. - I don't know on that score. Our goanna is a monitor (it has a forked tongue - so is more closely related to snakes actually) Iganuas have a fleshy tongue of 'true' lizards. Though we have a number of lizards that look like them, like the Beaded Dragon and particularly the Forest Dragon from up north, these are a totally different family of lizards.
