If you want to become the next Australian Roger Federer you might want to start practising as soon as possible. The perfect place for you, if you live in Surry Hills or any other neighbourhood around, is the Surry Hills Tennis Courts, in Prince Alfred Park.
There are five courts that anyone can hire. The rates depend if it's either weekdays or weekends but they will go from $18 to $26. For only $5 you can also hire racquets and balls, which is really convenient and allows you not to worry about carrying your own equipment.
If you are a beginner is not a problem, since classes can also be booked so that you can learn the basic rules and techniques of this sport.
