This photo has generally become known as 'the Ozenkadnook tiger photo'; in fact, the term 'Ozenkadnook tiger' was and is used for a supposed mystery beast (suspected by witnesses and locals to be a mainland Thylacine Thylacinus cynocephalus) seen since the 1880s across southwestern Victoria and southeastern South Australia (Healy & Cropper 1994). The specific photo is, therefore, better known as 'the Rilla Martin photo'.
Martin reported that, while on holiday one day in 1964, she was driving along between Goroke and Apsley. With time to spare, she chose to drive along the dirt track near Ozenkadnook. She'd been photographing relatives while at Goroke (where her cousin lived) and had the camera next to her, on the front seat. In the woods close to the road, she caught sight of an unusual animal, standing at the edge of the scrub. She stopped the car and snapped one photo, just as the animal began to run away [a close-up of its head is shown below].
