Australia operates an automated system that supposes welfare recipients owe the state money, unless they can prove to the robot that they don't.

At the moral level, whether this system is illegal under Australian law is a side issue. That many of the "debts" it collects are bogus is evil, but not the system's principal evil. The principal evil is that it squeezes poor people harder, when they are already squeezed to the crushing point.

Australia should tax the rich and businesses more, so as to give the poor a life that is not quite so hard.
