Hon DAVID PARKER: What I can assure the House is that the data checks that are carried out by Inland Revenue will be carried out again before every subsequent payment. The quality of the data will continue to improve. I would observe that the Inland Revenue Department is increasingly relying on automated datasets. This has enabled them to vastly reduce the cost of administration of tax services. Staffing numbers are down by close to 2,000 people as a consequence of those automated services. It not only saves Government administration and therefore taxpayers many, many hundreds of millions of dollars; it also rewards taxpayers by enabling them to get automated payments and refunds, and the datasets that are relied upon in these automated processes are constantly being improved.
