So I say to the Minister, why did he go from five days to 10 days? Where was the maths or the science or the evidence behind that, other than it was a good election slogan? Why did he decide to impose only $1 billion of extra cost? And, actually, where will the productivity gains be for the economy that pay that back? Because he's quick off the tongue, but slow off the hip. He hasn't been able to demonstrate that.
