Birth anomalies remain a significant public health problem in Australia. Despite this, we do not have quality national data on birth anomalies in Australia. In response to the AIHW's continuing commitment to birth anomalies as a core data collection, a review was conducted over the last year which was aimed at assessing the utility and scope of the National Congenital Malformations and Birth Defects Data Collection and making recommendations for its future. This report sets initial parameters for a new Australian Birth Anomalies System.
