Australia's Marnus Labuschagne in this file picture, celebrates after winning the third cricket Test match against India in Indore in March 2023. Labuschagne is most likely to be dropped ahead of the Australia tour of SA in October.

Former Australia captain Ricky Ponting believes Marnus Labuschagne’s position in the Test side has become ‘almost untenable’ following a prolonged period of poor form.

He also urged the selectors to make decisive changes ahead of October's three-match Test tour to South Africa. Labuschagne, 32, managed scores of just one, 31, and four during Australia's recent 1-1 series draw against Bangladesh at home.

The number three batter has now gone 43 Test innings without registering a century, with his last triple-figure score coming against England in the Ashes at Manchester in July 2023.

"This has been a very dominant side for a long period of time, but I think they have been carrying a few guys through the last couple of years. I think it is inevitable that change is made going to South Africa — Labuschagne's spot in the side is almost untenable, so they have to look at someone at No 3," Ponting told Sky Sports News on Monday.
