The Australians, inexperienced at one-day cricket, adopted a casual yet aggressive approach, often employing a full slips cordon for their opening bowlers. Gilmour was twelfth man in the early stages of the tournament, but selected for the semi-final against England at Headingley. On a day tailor-made for his style of bowling, he finished with 12 overs, 6 for 14, thus bowling out the opposition for 93. This was the first time that a bowler had taken 6 wickets in an ODI, and remained the best ODI bowling performance until Winston Davis claimed 7–51 in the 1983 competition.
