There is no scientific evidence to suggest that Australians are the most virulent swearers in the world. However, a 2015 study by the University of Melbourne found that Australian adults use swear words an average of 14.5 times per day, which is significantly higher than the global average of 3.5 times per day. The study also found that Australian men swear more often than women, and that younger people are more likely to swear than older people.

Despite these findings, it is important to note that swearing is not necessarily a sign of aggression or hostility. In fact, some studies have shown that swearing can actually be a positive thing, as it can help people to express their emotions, relieve stress, and bond with others.

Ultimately, the frequency with which people swear is a personal choice. There is no right or wrong answer, and what is considered acceptable in one culture may not be acceptable in another.
