Great photo pappy ,people also lived in similar "shacks" in Broken Hill ...NSW ( Aust) where I lived as a child / young adult.
In the early years in B.H . people were considered "well off" if they had used hession sugar bags sewn together as internal walls, which were painted with a white wash ,there's still homes standing in BH with hession bag walls .
The external walls were made from wood and iron ,in a town where summer temps are known to reach high 40c
