Australia's domination of the cricket World Cup is like Roger Federer's domination at the tennis majors from Wimbledon 2004 to Australian Open 2010. Either Federer or the players who defeated Federer (Marat Safin, Rafael Nadal, Novak Djokovic and Juan Martin Del Potro) won the 23 Grand Slams held in that phase.
West Indies (1979) was the last team to win the World Cup without beating Australia. That was the lone exception. Otherwise, either Australia have won the World Cup or the teams which defeated them.
