Hon DAVID PARKER (Minister of Revenue): Dealing with Nicola Willis' question—and I apologise again for forgetting your surname. I sometimes, I think, do it with my own children, just about. I'm terrible with names. The revenue varies from year to year, in part because of provisional terminal tax payments. I think it peaks at about $800 million, is the prediction, but the average over the longer term is expected to be $550 million per annum, which is why that number's been used by other members.
