This week, the robodebt royal commissioner, Catherine Holmes, summed up the tenor of the evidence so far: “Everybody says it was really somebody else’s doing, and it’s a bit hard to get to the bottom of whose doing it was.”

The hearings this fortnight focused primarily on the key period in late 2016 and early 2017 when the robodebt scheme exploded into public controversy.
