Yes, many, many, many Italians have made a HUGE contribution to the development post WW2 of Queensland, like they have all, over the Country. But.......stone walls were Kanaka stuff.A lot of Italians were up there working with the Kanakas sugar cane cutters they were.
I know this because my grandfather worked in Innisfail for 8 years in the 1930’s.
Four years ago I went up to Cairns and drove to Innisfail and saw a monument on behalf of the Italian sugar cane cutters in the area.
It was really lovely to see this... I do my own “who do I think I am” stuff
