I think when Larkham and Gits were around they had options who always hit the line running coming from depth. You don't see that at all now, the backline (or forward runners) are stationary as the 10 gets the ball then they're undeicded or confused as to which line option they should take.
All good teams from the ABs down to some well drilled 15As schoolboy team generally have a number of backline patterns they can run off any phase, say 4 for arguments sake. Then within those patterns they have up to 4 options which the 10 or first receiver can exploit as he chooses.
It looks to me as if the Wallabies have zero patterns and its up to the 10, who ever it may be, to decide on what to do for that phase, then for a runner to see what he is doing and interpret that. to execute like that at test rugby is going to take players with telepathy, to be honest.
