Wanungara Falls is in Lamington National Park.  It is at the headwaters of East Canungra Creek.    Therefore it starts near the border of Qld and NSW close to the Border Track.   It is approximately half way  between Binna Burra and O'Reilly's.  Many years ago there was a huge land slip which took away what would have been a NP track to the bottom of very long falls.
