An inquiry into the convictions of Kathleen Folbigg over the deaths of her four children will resume to examine scientific evidence and the diaries that played a role in her initial conviction.
Folbigg was convicted in 2003 for the manslaughter of her son Caleb, and the murder of her other son Patrick and two daughters Sarah and Laura.
The children died separately over the course of a decade, aged between 19 days and 18 months old.
