Help For American Tourist Attacked in Australia

This is my cousin being beaten up by a man in Australia for no reason My cousin is a great human being.  He travels the world teaching music, sharing love.  And this happened to him.  He is in a foreign country with no family.  we found out about the attack through a great soul that took the time to find us and call.
He is staying in the hospital from 2 to 3 weeks. Then he'll be able to fly home.   His dad is trying to make it there, be with him.   I ask anyone whom could help and whom could put themselves in his parents situation. Your child in a far away country and you trying to make it there to be with him.

Anything is greatly appreciated!

In advance thank you everyone and may your loving deed be returned.
