I found this result on the internet:
According to White people: To wander is to walk. To wonder is to think. The two ideas are mutually exclusive. They are separate. Hence they do âunsympathetic wanderingsâ; because they donât think while they walk. According to Indigenous people: the ideas are entangled together. The land and culture gives rise to a âpeople travellingâ.
However, there are multiple interpretations.
Some can say that they are both the same; you think when you walk. Thus the Indigenous people are 10000IQ.
A different one(mine, the one I recommend):
"Watching unsympathetic wanderings" - the wanderings of the colonists. They are unsympathetic and don't care about what they are doing. If the British are "wandering", then they are not thinking; they are just walking all over the Indigenous culture and "landscape of things sacred" without thinking how their actions will affect others.
