Group 1
Australia's high NRR effectively means they are through to the semi-finals of the Women's T20 World Cup, leaving three teams to fight for the other spot in Group 1.
Australia
Played: 4, Points: 8, NRR: 4.724
Remaining match: vs India
With eight points in their kitty and a stunning net run rate of 4.724 - their run rate with the bat (9.61) is almost twice their economy rate (4.89) - Australia are pretty much through to the semi-finals. Even if they lose to India by 100 runs, South Africa will have to win their last two matches by a combined margin of around 290 runs to go past Australia's NRR. They're so far ahead on run rate that they will almost certainly top the group even if they lose to India: if they lose to India by 60 runs, India will still need to beat Bangladesh by 100 runs to push Australia to second place.
India
Played: 3, Points: 4, NRR: 2.511
Remaining matches: vs Ban, Aus
The defeat to South Africa has put India's qualification chances in jeopardy. If they lose either of their two remaining matches, and if South Africa beat Netherlands and Bangladesh in their two remaining games, India will be knocked out. However, if India win their last two matches, they will almost certainly finish ahead of South Africa on NRR, thanks to the huge margins of their two wins. Even if India win each of their last two matches by just one run apiece, South Africa will have to win their two games by a combined margin of around 182 runs to finish above India (assuming totals of 180 by the team batting first).
South Africa
Played: 3, Points: 4, NRR: -0.546
Remaining matches: vs Neth, Ban
As explained above, South Africa's chances of making the semi-finals hinge of their winning their two remaining matches, and India not doing the same. If it comes down to NRR, India will almost certainly finish ahead. If India lose both matches, South Africa can qualify with six points as long as they stay ahead of Bangladesh.
Bangladesh
Played: 3, Points: 4, NRR: -0.641
Remaining matches: vs Ind, SA
Bangladesh have two tough matches coming up, against India and South Africa. Their poor net run rate means they can't compete with India on that parameter; hence they'll need to finish ahead of India on points, for which they'll need to beat them. If they lose on Thursday, their campaign will effectively be over, but wins in both matches will ensure qualification.
Group 2
With England already having qualified, only one place is up for grabs in Group 2, with three teams in contention.
West Indies
Played: 4, Points: 6, NRR: 0.008
Remaining match: vs Ireland
West Indies will qualify for sure if they beat Ireland on Saturday. If they lose, New Zealand or Sri Lanka could finish ahead of them with a win. Since New Zealand already have a higher NRR, a win by any margin will keep their NRR higher than West Indies'; if West Indies lose by 20 runs, Sri Lanka will need to win by 56 or more runs to finish with a better run rate (assuming totals of 180 by the team batting first). West Indies can avoid all these complications by beating Ireland and finishing on eight points.
New Zealand
Played: 4, Points: 4, NRR: 0.122
Remaining match: vs England
If New Zealand beat England and West Indies lose to Ireland, New Zealand will have an excellent chance to qualify thanks to their NRR. Even if they win by just one run, Sri Lanka's win margin against Scotland needs to be 85 or more runs for them to finish ahead on NRR.
Sri Lanka
Played: 4, Points: 4, NRR: -0.973
Remaining match: vs Scotland
As explained above, Sri Lanka's only hope is to beat Scotland by as big a margin as possible on Friday, and then hope for the following on Saturday: England beat New Zealand, and Ireland beat West Indies by a big enough margin so that Sri Lanka finish ahead of West Indies on NRR.
