This is an old photo that I had in my camera role that I thought nothing of at the time as I assumed it was Pseudonaja textilis (Common Brown). However, on revisiting it I think there's a solid chance it could be Demansia psammophis (Yellow-faced Whipsnake) based on the strong dorsal scale pattern and smooth grey-to-brown transition down the body. A Yellow-ish head is also visible. Appreciate the herpy expert thoughts!
