Australia had been expected to struggle against spin on day four, but the collapse that panned out on Tuesday morning was perhaps swifter than they too could have envisioned.
Ishant Sharma set the tone with his best spell of the series, but it was the spinners Ravindra Jadeja and R Ashwin who ran through the line-up to inflict an innings-and-135-run win on the hapless tourists.
India's second-biggest win over Australia was MS Dhoni's 22nd, making him the country's most successful Test captain ever.
