Geoffrey Dymock (born 21 July 1945) is a former Australian international cricketer. He played in 21 Test matches and 15 One Day Internationals between 1974 and 1980. On his debut, he took five wickets in the second innings against New Zealand in Adelaide in 1974. He was the third bowler to dismiss all eleven opposition players in a Test match, and remains one of only six bowlers to have achieved this. Dymock captained the Queensland cricket team for 9 matches between 1980 and 1982. In the words of Gideon Haigh Geoff Dymock would have played more Tests for Australia in an era less blessed with fast-bowling talent. As it was, he probably exceeded his own expectations when, sporting a bushranger's beard at the age of 34 in 1979-80, he wheeled down his left-arm seamers manfully in India, and against England and West Indies at home. No bowler, too, was so tireless a trier in the years when Queensland seemed likelier to win the FA Cup than the Sheffield Shield. Career Dymock made his first class debut in 1971–72. A highlight was 4–34 against South Australia. The following season he took 24 wickets at 26.08. 1973–74: International debut He had a very strong domestic season in 1973–74 with 51 wickets at 19.88. He made his test debut that summer against New Zealand, in the third test in Adelaide, replacing Tony Dell. Australia's selectors were trialling many new players and Dymock debuted alongside Alan Hurst and Ashley Woodcock; he took 2-44 and 5-58 and Australia won by an innings and 57 runs. 1974 Tour of New Zealand Dymock was picked on the 1974 tour of New Zealand. In the first test he took 3-77. Things were harder in the second test, Dymock going for 3-59 and 0-84; his second innings effort was considered particularly disappointing as New Zealand won their first test against Australia. Dymock was dropped for the third test. 1974–75 season Dymock began the 1974–75 season as a front-runner for test selection. He took 20 wickets at 16.8 early in the summer including five wickets against the touring English side. However the selectors preferred Lillee, Jeff Thomson and Max Walker. Dymock took 46 first class wickets at 23.95 that summer. He was picked for the 6th test, when Jeff Thomson was injured. Dymock went for 1-130 as Australia lost by an innings. 1975–76 and 1976–77 Dymock had a slower season
