This week, testimony has focused on the staff from a private mental health clinic in regional Queensland — two nurses and his former psychiatrist, known as Dr A — who were involved in Cauchi’s care between 2012 and 2020.

On Tuesday, Dr A gave her opinion about the motive behind his attack.

Sue Chrysanthou SC, representing the families of three of Cauchi’s victims — Ashlee Good, Jade Young, and Dawn Singleton — expressed that the statement “was contrary to the expert evidence” and “caused great distress” and “was shocking evidence to me and my clients”.

The records also indicate she said her son “isn’t doing very well” after stopping medication and “judging from notes on paper he has left around the place in the past week I have a feeling he is now hearing voices”.

Chrysanthou also raised the presence of “satanic material” in Cauchi’s handwritten notes found in his house, to which Dr A responded that the content stemmed from Cauchi’s “tormented mental state about sex and pornography”.

On Monday, both registered nurses who treated Cauchi said they were shocked to learn what he had done, and on Tuesday, Dr A said: “I offer my sincere apologies that this tragedy has happened”.
