This could have been a pic of a lifetime, except as is often happening, the dial on the camera had been knocked from auto to portrait and I did not notice. I took a better pic ten minutes later but the joey's rear legs were sticking out of the wallaby's pouch, instead of it's head. It is at a bird viewing area off the Arnhem Highway, NT.
Note in the pic the disturbed grass, especially to the left of the wallaby. A wild pig had been having a nice time there. They need to be eradicated now.
