India vs Australia: All you need to know

Agencies: The first of the remaining two Group 1 fixtures – India-Australia – will take place today in St. Lucia.

All four teams in Group 1 are still a mathematical chance to progress to the semi-finals heading into the final two matches.

Afghanistan and Bangladesh have an advantage by having the later of the two matches, meaning they'll know the exact situation they need to progress.

HIGHLIGHTS

*India lead Australia 19-11 in head-to-head records in T20Is. Of the 31 meetings between the two sides, one encounter ended in a no-result.

*India also edge the Aussies in T20 World Cups as the Men in Blue have three wins to their name against the Aussies' two.

*The Darren Sammy Stadium in St.Lucia, the venue for the high-voltage contest, have aided run-scoring in the ongoing edition of the tournament as evidenced by its average first innings total of 188 after five matches. The highest total of the tournament, 218-5 posted by the West Indies against Afghanistan, also came at this venue.

*India won two of their three previous matches at the venue and lost the other one while Australia, who played 10 so far, won six and lost four.

Every possible scenario in Australia's Super Eight group:

If Australia win and Afghanistan win

It would all come down to net run rate. Three teams – Australia, India and Afghanistan – would finish on two wins.

If both results are close victories, Australia would go through.

However, if Australia narrowly win and Afghanistan win big, it could be enough for the Afghans to leapfrog the Aussies on net run rate.

For example, if Australia win by 10 runs, Afghanistan would need to win by 46 runs to go past Australia's net run rate. If the Aussies win by one, Afghanistan would need a margin of 34 runs or greater.

If Australia win and Bangladesh win

This is the best situation for Australia and would guarantee their path to the next round, as both India and Australia would finish with two wins, while Bangladesh and Afghanistan finish with one.

Net run-rate (NRR) would then decide which of Australia and India would finish top, to determine not where they would play – India will play the Guyana semi-final – but who they would face.

England have already qualified from Group 2 after their huge win over the United States, with the winner of South Africa-West Indies (10.30am Monday AEST) to also progress.

If India win and Bangladesh win

Surprisingly, Australia would still be alive even if they lost to India. But, it would require an upset victory by Bangladesh over Afghanistan.

The NRR would come into account if Australia were smashed and Afghanistan only narrowly beaten. For example, if Australia lost by 31 runs and Afghanistan lost by just one run, Afghanistan would go through with the superior NRR.

But if the losing margins were the same or close enough, Australia would go through.

For Bangladesh to go through, they'd need to win by a minimum of 55 runs (depending on the India-Australia result).

If India win and Afghanistan win

Goodnight for Australia in this scenario, Australia would be stuck on one win while India and Afghanistan would go through on three and two wins respectively.

What happens if there's a washout?

A washout in the Australia-India match and a win to Afghanistan would send them through, while Australia would need to beat India if the Afghanistan-Bangladesh match is washed out and points shared. A washout in both matches would be enough for India and Australia to progress.
