Gilchrist and Australia started their 2007 World Cup campaign by winning all three of their matches in Group A, against Scotland, the Netherlands and South Africa. Australia won all six of their matches in the Super8 stage with little difficulty—the margins of victory were exceeded 80 runs or six wickets in every instance. They topped the table and thus qualifying for a semi-final rematch against fourth-placed South Africa. Gilchrist opened the Australian batting in each match, taking a pinch-hitting role in the opening powerplays. Initially successful in the group matches, scoring 46, 57 and 42, he failed in the first Super8 match against West Indies (7), but bounced back to score a second half-century (59 not out) in a ten-wicket victory against Bangladesh in a match drastically shortened due to rain. After a run of middling scores, he failed again in the final Super8 match against New Zealand.
