First of all, well done to Bangladesh on winning the Test Match.
Secondly, looking at the ICC Test rankings and using the predictor (
https://www.icc-cricket.com/rankings/mens/rankings-predictor/test), if results go as they should in the current series' being played plus the SA v. Bangladesh series in late September, we will slip to number 5 in the world behind India, England, SA and NZ;
Series / Predicted results
Ban V Aus - 1 all
Eng V WI - 2-1
SA v Ban - 2 nil
IF Australia lose 2-0 and the other two series go the way I have predicted we drop to 6th with Pakistan moving in to the 5th spot. Furthermore, a loss to the poms of 3-1 or worse would mean we drop to 7th.
Now some may say so what, but if the ICC test tiers proposal ever comes to fruition this could have major implications on which tier the Australian side enter especially if the ICC go black and white, top 6 and bottom 6 (not that I think it would happen that we enter tier 2 though you never know what is going to eventuate).
