There has been a six‐fold increase in the percentage of non‐Aboriginal births with a maternal alcohol diagnosis recorded during pregnancy and a 100‐fold increase for Aboriginal births. Around 70% of the mothers of children diagnosed with FAS did not have an alcohol diagnosis recorded during pregnancy and 18% of the mothers had no record of an alcohol diagnosis.</p> </sec> <sec id="bjo12167-sec-0008" sec-type="section"> <title>Conclusions</title> <p>Maternal alcohol exposure during pregnancy is significantly under‐ascertained.
