OK "No Watheroo, but there is Waneroo, and the Waneroo National Park"
Brain Fart! With better vision (no, I hadn't been drinking!) - without my contact lenses - for which I need reading glasses, but with naked eyes which allows me to see much better closer up!
Watheroo (and the National Park!) is between Perth & Geraldton
Wannewroo is near Mariginiup (largest local town)
Maybe I can send my eyes back instead! .. or my brain...
