Yes, most definitely. For some reason, this seems to be a question frequently searched in Australia despite the general consensus being the risk is nominal. Go-karting is definitely "safe," and very rarely do any of Sydney's go-karting tracks run into safety issues. While it's a fast-paced activity, qualified racing tracks like Hyper Karting and Extreme Indoor Karting adhere to strict regulations and practices to ensure the safety of all go-kart racers. Between officials whose job it is to observe drivers at all times, safety features like seatbelts and roll bars that balance practicality with performance, and the required protective gear (i.e. helmets, gloves, closed shoes, etc.), you almost have nothing to worry about.
