How is alcohol regulated and consumed in Australia?

In Australia, alcohol is often portrayed as part of social life—especially at BBQs, sporting events, and public holidays. Customs like BYO, where you bring your own drinks to gatherings, and 'shouting' rounds at the pub are part of the culture. However, because of the health risks associated with alcohol, there are regulations in place. It’s also important to understand the laws around the legal drinking age, where you can buy or consume alcohol, and how these rules vary across states and territories.
