1. The two farmers:
Seem quite blissful although they are isolated in the Australian outback
The fences:
Associated to their cheerfulness
Must have been extremely hard-working
The Aboriginal hunter:
Seems to blend in his surroundings
His position symbolically links him to his native land
His weapon: he succeeds in on what nature has to offer

2. Although the two picture seem to be in sharp contrast at first:
modern-day sedentary farmers who have claimed ownership of the land (fences)
A nomadic native Australian (who blends into the bush)
* The people seem to enjoy a harmonious relationship with the land
* Given the representation of such an arid landscape, Australia must have been quite a challenging land to settle in
