A strangler Fig at Border Ranges National Park, NSW.
These trees find a host tree and can literally squeeze the life out of them by growing downward and upward.They are the enormous giants of the forest. This one is hollow, as the host tree died. Sometimes you can climb up the inside. This one just got a big hug from my friend Anthony.
(btw, I am standing up when I took this, just to give some scale)
Great photo
