While the Wallabies try to fix their porous defence, their Scottish hosts are trying to shore up their own rearguard as Murrayfield prepares for a battle royal between two "wounded" sides in urgent need of a boost.
The problems faced by Les Kiss's leaky outfit were highlighted in the 45-22 thrashing at Twickenham by England, which meant they have now conceded 176 points in their last four Tests, the most ever over any equivalent quartet of matches in the Wallabies' annals.
Yet while Kiss and defence coach Scott McLeod continued to try to find solutions to their increasingly apparent defensive weaknesses, the same urgent exercise is being undertaken in the Scottish camp after Gregor Townsend's side shipped 43 points to the All Blacks at their Edinburgh fortress last weekend.
