Debutant Joe Mennie falls in the same over, lbw to a low full toss for a second ball duck. Even a DRS referral can't save him, with 'umpire's call' verdict coming up for a ball which was clipping leg stump. 7-150.

Debutant Callum Ferguson follows in similar fashion to Voges, having attempted to sway out of the way of the ball only for the delivery to jag in and catch his glove on the way through to the slips. Australia 5-140.

Under-pressure veteran Adam Voges adds two runs before embarrassingly directing a short ball he attempted to leave straight to gully. Australia 4-135.
