It is too early to say but I have a feeling that anything above 400 runs would make it hard for Indian batters. Australia has lost 7 wickets but the they have already scored 422 runs. If the tail enders are able to add an extra 50 runs to the scoreboard then Australia would have a psychological advantage. Smith and Head batted like they won't be a next day. Just look at their SR, head has 93 and Smith has 45. That is very agressive batting by both of them. Expecting Australia's first innings to end today and India to start batting.
Indian ballers should stop Australia from making any more runs and take 3 wickets as quickly as possible because 430 is already a huge trail to follow, India should start batting today so that can come back stronger in giving lead and have time margin in hand .
Australia literally surprised everyone with their batting , India definitely didn't have this in mind before choosing to field first.
