Australia follow-on at home for first time in 31 years

1988 - The last time Australia were asked to follow-on at home, before India's enforcing it in the fourth Test in Sydney. England were the last team to do so, also at SCG, in 1988. Australia had played 172 consecutive home Tests without following-on before this SCG Test.

4 - Times India have asked Australia to follow-on. However, this was the first time since the 1986 New Year's Test in Sydney. The other two instances of India asking Australia to bat again are from the 1979-80 home series, in Delhi and Mumbai.

2005 - The last time Australia followed-on anywhere in Tests. England had enforced it at Trent Bridge. It is the only other instance in last 30 years that Australia have followed-on in Tests.

322 - India's first-innings lead in this Test, their second-biggest against Australia and the biggest in Australia. They took a 400-run lead at Eden Gardens in 1998 which remains their largest. The 292-run lead in the last Test at MCG is the fourth-highest lead for India versus Australia. Thus, India's top-two leads in Australia have come in this series.

5/99 - Kuldeep Yadav's figures - the second-best by a visiting left-arm wristspinner in Australia. Johnny Wardle had picked up 5 for 79 at SCG in 1955. That's also the only other five-for by an overseas wristspinner in Australia. It was Kuldeep's second five-wicket haul in six Tests.
