How do Cubans obtain an Australian Visa

Hi everyone,
I have a close friend who is wanting to come and visit me with his wife and 2 children.  Apparently there is no Australian embassy in Cuba.  Does anyone know the procedure he and his family need to take to obtain an Australian Visa?

hope this will help.

Thankyou I will forward this on.  From what I know there is no Australian Embassy in Cuba.  And the Canadian Embassy is for Australians in Cuba.
Thanks again
