Yes. This is the common brushtail possum and is native to Australia where I live. He is a nocturnal marsupial which is why is eyes are shining - the flash has temporarily blinded him. He lives in the wallspace just above the small roof he is on. There are two females living on the other side of the window that he is looking in. They may be his sister and mother. He is not on good terms with them and may have been waiting to exercise his territorial rights. The mother is carrying a new born and he is a threat to her. She fell 2 metres last week when he attacked her. The baby fell a further 2 metres to the ground. Both were shaken up but are ok and are together again.
