Posthumous conception, the ability to conceive a child after the death of one partner, is increasingly prevalent due to advances in Artificial Reproduction Technology (ART). This paper considers the complexities surrounding the practice in Australia, focusing primarily on the ethical and legal dimensions. It observes that state-based regulations in Australia create disparities in accessibility: some states prohibit the procedure without the deceased’s written consent, while others permit it based on guidelines or lack explicit prohibitions. Addressing the juxtaposition of Will Theory and Interest Theory, it emphasises the ongoing debate on whether rights, particularly reproductive autonomy, outlive a person’s demise. Finally, the paper highlights an evident inconsistency in Australian legislation and promotes a uniform approach across states.
