Millie lies between Little Bumble Creek and Millie Creek on the crossroads to Bellata, Rowena, Collarenebri, Burren Junction, Gurley and Moree. The beautiful Millie Monument is a landmark built to commemorate the memory of late Trooper James Daniel Duff killed in the Boer War. Millie was once home to the Millie Hotel and Millie Post Office.
