'Taboo fiction' author can't hide in child abuse case

The author of a "taboo fiction" novel allegedly containing child abuse material has been unable to hide her identity despite receiving death threats online.

Lauren Tesolin-Mastrosa, 33, wrote the book Daddy's Little Toy under her pen name Tori Woods.

The Christian charity marketing executive issued a pre-release of the novel to around 20 advanced readers in March.

Police were notified about its contents and the woman from Quakers Hill, in Sydney's northwest, was arrested on March 21.

At a hearing on Monday, her lawyer Mickaela Mate said the allegedly offensive content was between fictional characters who were two consenting adults.

"(It) is a fantasy within a fiction and hence there are no victims," the solicitor said.

On Wednesday, Tesolin-Mastrosa lost her bid at Blacktown Local Court to shield her identity from the public.

Earlier in the week, as the author's husband Adam Mastrosa watched on, Ms Mate argued that the order barring publication of her client's details or even the case was necessary.

Online threats made against the woman and her husband, including from a TikToker who referred to the electric chair, were high enough that her safety was at risk, the court was told.

Tesolin-Mastrosa had experienced distress due to these comments against her because child abuse material was seen as heinous.

"Being called a pedophile online is something that sticks in the community," Ms Mate said.

She also argued that any magistrate who heard the matter in future could be influenced because they had read about the widely reported "memorable" case.

The case stuck out because her client worked for a Christian charity while writing about allegedly taboo material, the court was told.

"It is so memorable because my client is otherwise ... so ordinary," Ms Mate said.

Barrister Matthew Lewis SC, representing News Corp, opposed any suppression.

He said details about the case had already gone viral worldwide.

"It's almost akin to trying to stop the tide - it's gone," he said.

Magistrate Rami Attia declined to make the orders saying there was no expert evidence that Tesolin-Mastrosa was at risk of harm or self-harm from further reporting of the case.

This was despite the author's "deep-seated fear" of attending court and her solicitor's genuine concerns for her wellbeing, the magistrate noted.

Furthermore none of the online threats were elevated enough to warrant the court shielding her identity, he said.

Any suggestion a magistrate could be influenced by media reports of the matter was also rejected.

Tesolin-Mastrosa did not appear in court for the hearings.

She has pleaded not guilty to possessing, disseminating, and producing child abuse material.

Her matter will return to court on June 5.
