All the World Rugby ranking permutations for this weekend's Test matches.
There will be more than just bragging rights at stake when England host the Wallabies at Twickenham on Saturday. Separated by 0.62 of a rating point, either side could regain third place in the rankings, ahead of Ireland, if they win by more than 15 points.
Any sort of win for the Wallabies will ensure they rise to fourth, with the hosts slipping to fifth. An English victory by any margin will see the top five go unchanged, as Australia cannot slip lower.
Regardless of the result in Cardiff, the Springboks are assured of second place behind New Zealand on the rankings, while sixth-ranked Wales will climb to fifth if they beat the Boks by more than 15 and England lose to Australia by the same margin. The Red Roses will then drop to sixth.
The Dragons could, however, slide to seventh in the event of another defeat against one of the southern hemisphere big three, with France moving into sixth spot by default.
