Australian batters have looked far from being comfortable against the Indian spinners in the first two Border-Gavaskar Trophy Tests.

India’s seasoned spin duo of Ravindra Jadeja and R Ashwin have taken 31 of Australia’s 40 wickets as the visitors’ four innings have folded for 177, 91, 263 and 113 in Nagpur and Delhi.

Amidst Australia’s struggles in the Indian conditions, former India head coach Ravi Shastri has advised the touring batters to go back to basics and play with more patience.

"I think application (has let them down) more than anything else. The lack of belief in their own defence,” Shastri said on the latest episode of The ICC Review.

"The lack of application and the lack of discipline was unreal and Australia paid for it big time.”

Shastri believes aggressive approach has led to the downfall of Australian batters in Nagpur and Delhi as they lost both Tests inside three days.

"It's very important to go back to the basics, go back to the drawing board,” he said.

“If you don't trust your defence, you have no chance because that's when you entertain thoughts of breaking free, much quicker than you normally should.

"Sometimes you've got to spend some time at the crease, but how are you going to spend some time at the crease if you don't trust your defence?

“But I didn't see one Australian batsman (do that). What surprised me was some of their most senior players also came out there and looked to do things out of the ordinary, something they're not used to far quicker than later. And especially in conditions that suit the Indians.

"So I think it's patience, it's application, it's discipline and trusting your defence."

Australia need to avoid a 4-0 series sweep to secure their place in the ICC World Test Championship final, scheduled to be played at The Oval from June 7 to 11. There's every chance that India and Australia could meet again in the WTC final.

"A 4-0 win here psychologically does send a strong signal to the opposition," Shastri stated.

"There will be an impact, but conditions are different as Australia will have their fast bowlers back as a lot of them are injured. But that psychological dent will make India believe that, even in those conditions, they're good enough to upstage Australia," he further remarked.
