While we are on the subject of discrimination I suggest you google 'Len Waters aboriginal RAAF pilot.
It was disgraceful the way he was treated after WW2.
Briefly, he flew 95 missions on Kittyhawks with 78 Sqn. After the war he applied for a CPL as he wanted a career in aviation. DCA refused to grant him a licence.
Seems the RSL weren't interested in helping him out either.
