Thank you all, that's brilliant!
Yes, I did think the term 'squatter' a very odd one for Eric to use, given his family background -- actually owning the land sounds much more plausible. He clearly did acquire some farming skills, though, as on one occasion when his plane had made a forced landing in France during the war he milked a cow in order to have milk for his tea ...
If Eric is actually mentioned from about 1896 he would only be 9, which suggests that his father Harry made the original purchase,
I've been through Trove looking up 'Eric' references (and his father and other relatives too) which is where I got the Point Pure/Gatton references from.
As I commented on a previous RootsChat thread about Eric, I'm astonished how frequently the Conrans travelled between England and Australia -- sometimes three times in a year. Although Eric became a British army officer in 1909, he continued to visit Gatton right up until 1914.
