My great gran swears she saw one. she got up early morning to make a coffee and she was looking out the window and there it was staring back at her she said she dropped the coffee and yelled for her husband. by the time he got there and she looked away it was gone. she always said it was about 20m away and she will never forget it. from what i herd was it was the us military that came over here along time ago, and the panther where there mascot. Aus gov caught wind of it told them they had to depose of them, but the didnt they let them go. but thats what i have been told
