Melbourne
Melbourne Cricket Ground (MCG) is the centerpiece of the city's thriving sports culture. You don't have to know the rules to enjoy yourself—locals are more than happy to help newbies understand Aussie Rules Football ("footy") or cricket. This venue hosts some of the country's most important sports matches, including the annual Boxing Day Test, an international cricket match that plays to crowds upwards of 100,000, as well as the Australian Open, where the world's best tennis players converge each January. Sport is so important in Melbourne that even if you don't visit the MCG, you'll still encounter athletes—whether it's rowers on the Yarra or runners waking up early to crisscross the city grid.
