AAWT Canberra to Walhalla duration?

Hi,
I've always wanted to walk the entire AAWT in one go, but I've always thought I needed a couple of months to do it , and therefore needed to be retired etc.
Just wondering about the feasibility of doing it in say 4 weeks? I'm curious about the day lengths, experiences, etc of those who have done it all in less than a month .
John Chapman has a 35 day itineray for fast walkers, with no rest days . To get that down to 28 days means shaving a day off each section and an average of mainly 28km/day.
Interested in any thoughts.
