Electronic Review

Tournament info

The Australian Open uses Hawk-Eye technology to conduct electronic reviews of disputed line calls. All Hawk-Eye systems use high-speed cameras to generate visual images that enable the tracking of the flight path of a struck tennis ball, determining whether the tennis ball landed in or out of bounds.

Hawk-Eye technology is used on all match courts for the following events:  

  • Men’s Singles
  • Women’s Singles
  • Men’s Doubles
  • Women’s Doubles
  • Mixed Doubles

The Australian Open adopts the ‘three-plus-one’ electronic review system. Players will receive three incorrect challenges during each set and a fourth challenge if a set goes to a tiebreaker.
