"Litoria peronii" - also called the laughing tree frog or maniacal cackle frog (see source if you're curious why, though I'm sure you can guess) Quite uncommonly for frogs, they have cross-shaped irises (though they are not cross-eyed) and they don't enjoy being in water. However, they don't mind urban areas and they can climb on almost anything except metal. (Special thanks to @mialinay for the vid that let me know these guys exist)
Their eyes also...caught my eye haha
