India's T20I series against Australia serves as a platform for fine-tuning strategies and addressing key player roles for the upcoming challenge against South Africa. The fifth T20I, set to take place at the Chinnaswamy Stadium, is a crucial workshop for the Indian team to evaluate resources and test combinations before the series against the Proteas starting on December 10. Shreyas Iyer and Deepak Chahar, both returning to the shortest format after a hiatus, are in focus for the workshop.
