Spark's streaming sport service started operation on Thursday, just in time for this weekend’s Australian Grand Prix.
The service is still in beta mode. In practice this means while most aspects are now working, the company will make improvements and add features in coming weeks.
For now Spark Sport is on the web and Apple and Android devices. Sports are shown in real time, viewers can rewind up to four hours. Once an event finishes it will be available on demand.
Early viewers will be able to see Formula One racing, the World Rally Championships, Professional Hockey and NBA TV.
Spark Sport has added the One Championship, which features martial arts such as Muay Thai, Kickboxing, Mixed Martial Arts (MMA) and Karate. The first event, One Hero, starts on March 25.
Also new is Edge Sport, a round the clock action sport channel which includes skiing, snowboarding, biking, surfing, skating and motorsports.
Spark says more sports will be added in coming weeks. The service will show sports in HD resolution where possible and adjust to lower video quality as necessary.
