[1][2] Gerry Austin was born in Dunedin and educated at Otago Boys' High School.
[5] Austin top-scored in each innings with 35 and 52 in Otago's match against the Melbourne Cricket Club in March 1900.
[7] In the 1910-11 senior club cricket season in Dunedin, Austin scored four of the 21 centuries, but he was unavailable to play for Otago owing to work commitments.
[8] He made his highest first-class score of 64 against Canterbury in the Plunket Shield in 1911–12, adding 170 for the second wicket with Cyril Hopkins.
He added, however, that Austin's results were disappointing for so capable a player, and suggested that perhaps nerves got the better of him in big cricket.
