In recent months, Giuffre had become estranged from her husband, Robert Giuffre, who had custody of their children.
She had been due to appear before a Perth magistrate for the alleged breach of a domestic violence restraining order in June.
Ms Louden said she would have ensured Giuffre had received more help had she thought she was a suicide risk.
Her death has been referred to the Perth coroner to be investigated. Toxicology tests are expected to be carried out in the coming days.
‘Brave survivor’
Meanwhile, UK charity Rape Crisis said it would honour Giuffre as the “remarkable woman, brave survivor, and fierce advocate that she was”.
It added: “Virginia showed immense courage in speaking out about her experiences of abuse, sending a message to all survivors that neither money nor power should protect anyone from the consequences of their actions.
“No survivor of sexual violence or abuse should ever face stigma or shame in speaking out about what has happened to them, but far too many still do.
“Despite being subjected to appalling hostility and victim-blame, Virginia was steadfast in her pursuit of justice. Her voice and courage provided inspiration and hope to, no doubt, countless other survivors.”
