I'd replied to your post in the other thread:
Not a TA here. I first got Sabre access through a subscription-based agency in the US, got the link off Flyertalk. That wasn't super useful as a lot of bookings these days are SITI (Sold Inside Ticketed Inside - so you'd need to be associated with an Australia-based agency to sell ex-Australia fares for instance). But it was useful for constructing RTWs before handing the PNR to AA for ticketing (so no unreasonable airline-imposed ticketing deadline to put up with) as well as checking up on good deal published premium fares out of Whateverstan. Currently I get access to Sabre through my employer's corporate TA which makes it easier to do ex-Australia bookings.

Does this mean that you are allowed to make your own bookings? Does the TA take care of the ticketing?
SITI can cause some trouble. What I have noticed with QF though is that they restrict the cheap booking classes for the European markets. When I get my TA here to book and ticket the flights for my European friends they save 100's of Euros.
*Bump*
Is there any update to this, how would a member of the public or a business wanting to arrange it's own travel gain access to a GDS? Is there some sort of process?
I know in the US you can sign up to Sabre for about $45/month, but you need to be affiliated with a travel agency to ticket anything.
No idea about here.
