 The task of the Australian selectors was easier as they kept the same XI from Brisbane, but exchanged the twelfth man Kerry O'Keeffe for the off-spinner Ashley Mallett.Like Titmus Mallett was able to flight the ball, so Terry Jenner was made twelfth man and Mallett played.Ian Chappell won the toss and took the extraordinary decision to field, believing that the England batsmen were still demoralised from their experience at Brisbane and that a dose of fast bowling on the quickest pitch in Australia might break them.
