Chatswood Youth Centre is, as it says, located in Chatswood just next to the carpark near Westfield Shopping Centre.
On a clear day the the outdoor courts on the roof are used by many people from 2.00-6.00 every day just to play some basketball and have fun. This area has around 6 hoops at a time around the court, leaving enough room for some friendly 3v3 or more games with friends and with random people you meet. Also on the roof is a few punching bags, weights and a table tennis set up.
When raining, the courts upstairs are closed and the area underneath becomes the main place to be. Inside the Youth Centre you can play table tennis, use the pool tables, play chess or be a gamer with either the Xbox 360's, PlayStations or computers.
On top of this, bus and train stations are just 1 minute walk from the Youth centre, with a carpark underneath and next to it, making it easy to get to no matter what transport you use.
