At the highest level, even extreme pace is cannon-fodder unless you can move the ball. Milne and Ferguson don't, they would be one-dimensional in test cricket. This is what made Bond a freak.

Starc swings the ball. Hazelwood and Cummins hit the seam. Hazelwood is metronomic and relentless, Cummins bowls a heavy ball. Ferguson can't replicate what they offer.
The most "Australian" type bowler we have is Jamieson, who is just quick enough.
