Charles George Macartney, born in Maitland, NSW, in 1886, made his Test debut at the Sydney Cricket Ground on 13 December 1907 against Plum Warner's England side captained on the field by F.L. Fane. He was picked primarily as a left-arm spinner with handy lower-order batting; he had played seven first-class matches and was 21 years old.
In the first innings he batted at nine, scoring 35 in just under an hour. The story, told by Macartney himself in later years, was that as he came in he adopted a bristly, confident posture at the wicket and immediately began to look for runs. The Kent and England batsman KL Hutchings, fielding at slip, called out something to the effect of 'Here comes the Governor-General' — the joke being that the young debutant from rural NSW was strutting around as if he owned the place.
The nickname stuck. Macartney would carry it through his career, and it was eventually adopted without irony as he became one of Australia's great attacking batsmen of the 1920s. He scored 99 before lunch on the first day at Headingley in 1926 — equalling Trumper's 1902 feat at Old Trafford — and made a Test triple-hundred against Otago in 1924-25. His final Test record was 2,131 runs at 41.78 and 45 wickets at 27.55 over 35 matches between 1907 and 1926.
