Marnus Labuschagne has been dismissed for a duck in a damaging blow to Australia's top order on day two of the third Test against South Africa.

The middle-order batter lasted just five balls before being sent back to the pavilion, leaving Australia in a precarious position as their top order crumbled under pressure from the South African attack.

Labuschagne's failure to trouble the scorers will be a significant concern for the Australian side, with the team relying heavily on their experienced batters to build a competitive total in the match.
