Senator ROBERTS (Queensland) (14:28): My question is to the Minister representing the Minister for Health and Aged Care, Senator Gallagher. It has been four weeks since the Australian Bureau of Statistics published data showing a 67 per cent reduction in Australia's monthly birthrate between July and December 2021 as compared to the long-term average—a startling decrease. I drew attention to this data during Senate estimates, hoping for some reassurance. None was forthcoming. Let me ask again: Minister, why has Australia's birthrate declined from 30 June 2021 to 31 December 2021, revealing a 70 per cent reduction?
