according to my source I am using which makes this game very easy, the only 2 species found in WA and NT are Diporiphora bennettii and Diporiphora albilabris though I think it is very outdated, need to get one of my field guides. obviously its not either as they were already guessed and where wrong.
edit: geckoman I see your also using what I am lol, makes it easy hey.
