Brisbane: Australia's thrilling Twenty20 win at the Gabba on Tuesday ended in a cloud of drama with suggestions of a laser light being flashed at South African fielders.
Television coverage picked up a green light that flashed across rookie Proteas fast bowler Wayne Parnell as he attempted a difficult catch in the outfield.
Parnell's failed diving attempt off a Mike Hussey skier at long-off came as Australia neared victory in a tense finish.
Hussey went on to score an unbeaten 53 to lead the home side to a six-wicket win with Cameron White, who belted 40 off 18 balls.
The Sydney Morning Herald quoted Proteas skipper Johan Botha as denying that Parnell had made a complaint after the miss, but said he would investigate the matter.
