Maddinson, Harper released, Smith set for fitness test

Australia will introduce a new opening combination for the deciding Test against South Africa in Cape Town after releasing Nic Maddinson and back-up wicketkeeper Sam Harper from the squad. Maddinson was omitted after passing double figures just once across four innings since his surprise recall, opening the door for Matthew Renshaw to potentially return to the top order. Harper departs as Josh Inglis returns from a broken finger.

Selectors are also assessing the top order as Steve Smith undergoes a fitness test on a neck issue ahead of the match. Cameron Green is pushing to reclaim his spot at No. 5, placing pressure on Marnus Labuschagne, who has struggled to convert starts into big scores. Meanwhile, spinner Nathan Lyon is in contention to rejoin the bowling attack after sitting out the previous match.
