I've been browsing the Official Record of the Tasmanian International Exhibition book that Professor Castaneda has posted.

That's the entirety of it, or at least it should bring you to the entirety of it.
If you look at the index it shows how much of the book/ exhibition was dedicated to the nature of Tasmania.
There is a portion that talks about how Tasmania was one of the healthiest colonies and how it had a much lower death rate than that of the European colonies. (I would post the actual portion, but I'm not sure how to get the picture of it.  It is on page 14).
There is also another section that talks about the large display made by the agriculturalists and horticulturalists of the colony on page 17
I also think that a portion of the Inaugural Cantata should be incorporated somehow. (page 39)
"But yesterday we had no place
On history's board and varied page;
But yesterday a savage race
Dominion owned where now we wage
The arts that from a grateful soil
Abundance bring, or proudly rear
The shrines wherein the priests of toil
Hold worship through the changing year;
The arts unknown to people rude
Yet can the poorest nation bless,
And make the wildest solitude"
