Supporters of the Australian national soccer team, the Socceroos, audibly booed the United States national anthem before their FIFA World Cup match at Federation Square in Melbourne. The incident occurred as both teams prepared to compete in the international tournament. The booing was sustained and clearly audible, demonstrating a level of animosity from the Australian crowd towards the visiting team. Authorities have not commented on the incident, and it remains unclear if any repercussions will follow. The protest highlights the passionate, and sometimes contentious, atmosphere surrounding international sporting events. The match itself proceeded despite the pre-game demonstration of disapproval. This is not the first instance of anthem protests at sporting events, but it is notable given the high profile of the World Cup.
