Finally!
This is the alpha male kangaroo who guards the path to my letterbox. I have photos of his harem and they are all sweet and gentle looking - but this bastard sits back and props as I go outside down the path to the gate. Every move I make seems to be a challenge to him. Last time -  he sat back so far and raised up his body by using his tail as a third leg o front paws and claws raised  - as I drove in my big white van down to the gate (too bloody scared to walk) he did not move a muscle except to make himself look bigger - and he was bigger about a foot taller than me and with claws to die for - somehow this was not the Skippy I remember from my early days...
