Listener, thx for the post and link.
I remember SBF saying a few years back that the org seems to be concentrating on making a few Bethels in the world key ones (like the one in Selters). So the Aussie branch is clearly one of them if it rates its own media production center. The "replica of an historical Biblical site" is an interesting twist. As some have commented here and on the reddit post, perhaps they are indeed launching into tourism of a sort. I suspect too that they may feel a bit intimidated by Hobby Lobby's Steve Geen and his massive Museum of the Bible in Washington DC, so they want to imitate that in very minor ways like Mark Sanderson's "museum" in Warwick and now this "replica" in Sydney.
Maybe they view this as a way to keep the money flowing in from faithful Witnesses who will visit and contribute. Finally, do we see the heavy hand of Geoffrey Jackson here?
