David Wilson (68)
The penalty, which led to the PT was for a "whip wheel" from when Skelton stopped pushing and the Oz TH disappears backwards on rollerskates a couple of seconds after this screen shot.
Also Law 20.3 (g)A flanker may bind onto the scrum at any angle, provided the flanker is properly bound.
But I take your point, it would be nice if the commentators had explained (or even knew?) that.
Not to mention the fact that the half put the ball in at 45% - so really should have been a Wallabies FK before most of the other stuff happened.
