A reader sent me mail asking whether I had "permission" to use the names of the people from the MCA. I hadn't. I assume that it is like referring to Mrs. Merkel or John Wayne. The officers/staff of the MCA are listed online. I haven't placed real folks in situations that might be libelous.
And no one seems to think that mentioning Heysen or Dupain or Fred Williams was offending to real entities.
Perhaps I should note that names of real people at U. of Sydney and UNSW have been used, too.
