Grant was at one time a saw miller, losing the tips of three fingers in industrial accidents. Grant is one of the few people still living to have heard native speakers of his tribe's Wiradjuri language, having been brought up as a child around native speakers of his grandfather's generation, notably his grandfather, Wilfred Johnson. Johnson was arrested in the late 1940s after a policeman overheard him calling to his son in Wiradjuri - it was forbidden to use Aboriginal languages in public - and he was detained overnight in a cell. From that day on, his grandfather refrained from speaking his native language in public. He has been crucial to the reconstruction of the Wiradjuri language along with Dr John Rudder, with whom he travels among the Wiradjuri people, teaching their language. From a small base of anthropological records, they have rebuilt the spoken and sung language among both urban and rural tribal members. In 2005 they published "A New Wiradjuri Dictionary”, running to some 600 pages. In 2006 this work was recognised with the Deadly Award of Outstanding Achievement in Aboriginal and Torres Strait Islander Education.
Personal
Grant is the father of Australian and international television personality and journalist, Stan Grant. In May 2017, the son interviewed his father to commemorate the 50th anniversary of the 1967 referendum to alter the Constitution of Australia to recognise Aboriginal people. The father discussed how he experienced overt racism as a young man. "Racism was in your face. I was called nigger, boong, coon, abbo, blackie, you name it, I copped it all the time. You couldn't own a block of land, you couldn't own a house, you had to rent one. You couldn't be out late at night, you had to gone by sundown from the street. There were many, many, things we couldn't do." Yet, he later noted differences in how people treated him. "In 69-70 there I noticed there were some changes being made. The racism that was in our face, wasn't there, it was behind us a bit, it was more of an undercurrent. It gave us the right to be citizens, in our country that was ours in the first place."
