Gaff,

I believe Cogger uses a mean length excluding juveniles. FWIW I've see and collected EBS over 6 feet and supposing that if they were not resisting then that may have gone quite a bit longer. "Observer" estimation of lengths can be guesstimated but are in part a function of body mass and condition. BTW there is a zoological rule of thumb that states that "in extremis" size is contingent upon extremes of climate. See Chappel Island tiger snakes and the papuensis species for a lead.

Of Hoser I have no knowledge. The issue of aggression is relative to species, most especially circumstance; and season.
