Going to church does not only mean you must be holy to visit them, sometimes it can also mean understanding and learning about both the culture and history of a certain place/country through the most historical buildings it has; in some cases, happen to be the church.
Schoolies is the most awaited time for high schoolers in Australia. Once they are done with the studies, they head on to their dream destinations to have the time of their lives. After high school, you may move to a new city to get admission at a university, so you may not be able to hang out with your friends for a long time. Schoolies week provides graduates with a great opportunity to spend some time with their friends.
