Field hockey is like playing soccer with a small ball and sticks that have a flat bottom. In Australia, it's a popular game that people play both in school and outside of school. You try to hit the ball into the other team's goal while also trying to stop them from hitting the ball into your goal.
Players wear special shoes with small spikes on the bottom to help them not slip on the field, which is like a big grassy area. They also wear special clothing to protect them from getting hurt by the stick or ball.
There are rules that players have to follow, like not hitting the ball too high or hitting other players with their stick. They also have to work together as a team and communicate with each other to win the game.
Some people in Australia are really good at field hockey and play it professionally. They practice a lot and travel around to different places to compete against other teams. But even if you just play for fun with your friends, it's a great way to get exercise and have fun outside!
