Park had been a Melbourne University medical student and a stylish batsman for Victoria before the war. He enlisted in the AAMC, qualified as a doctor on active service, and served at field hospitals in France through 1916-1918. Returning to Melbourne in late 1919, he resumed club cricket for University and quickly returned to form. The following Australian summer (1920-21) he was selected for the second Test against Warwick Armstrong's England side at the MCG. He came in at the fall of the first wicket, played at and missed the first ball he received from Howard Sussex, and was bowled. Australian folklore — repeated in Wisden, Bill Frindall and Bill O'Reilly's columns — holds that his wife, in the crowd, missed the dismissal because she had bent down to pick up her knitting. He was not picked again. His career Test record reads: one match, one innings, no not-outs, 0 runs, average 0, one ball faced. His daughter married Ian Johnson, who later captained Australia.
