Cotter, born in Sydney in 1883, was one of the few genuinely fast bowlers of the Edwardian era. Where men like Bill Lockwood and Tom Richardson had been called 'fast' in the 1890s, the prevailing theme of the 1900s was variation, swerve and spin. Cotter ran in hard, bowled short with intent, and did not pretend the bouncer was anything other than a weapon. The reaction in England in 1905 was outrage — Wisden noted that 'his methods aroused some controversy' — but he was effective.
On the 1905 tour Cotter took 124 first-class wickets, including 7 for 148 in the second innings of the fifth Test at The Oval. By the 1907-08 Ashes at home he was Australia's leading strike bowler. He toured England again in 1909 (taking 6 for 95 in the Oval Test) and played his last Test in 1912. His Test career ended with 89 wickets at 28.64 — modest figures by modern standards but impressive given the prevailing reluctance of contemporaries to bowl the short ball.
When the Great War began Cotter enlisted in the Australian Imperial Force, served at Gallipoli as a stretcher-bearer, and died on 31 October 1917 during the Light Horse mounted charge at Beersheba. He was 33. He remains the only Australian Test cricketer killed in the First World War.
