Asian House Gecko
Asian House Geckoes first appeared in Australia in 1983 near Brisbane and has since spread to much of Queensland. They can be heard at night giving their chuckling call and are commonly found on the outside of houses. It's not entirely clear that they are displacing native species, such as the Eastern Dtella, but they occur in the same habitat and eat the same insects. The Asian House Gecko is smaller than the Dtella with a body length of ~7.5. As with several other gecko species, they are paler at night.
