I feel like it boils down to options a bit.

If I don't take the opportunity to work in Australian mines, will I have a reasonable opportunity to find work and provide a comfortable living for my family?

If that answer would change whether or not I'd work in a mine, I'd consider that the work may be exploitative of a regional work shortage. At that point someone might feel as though sacrificing their health is their only option, and an informed decision is much harder to make.

Like many ethical questions, it warrants discussion even though there may not be a "right" answer either way.
