A boast by Australia’s youngest convicted murderer that police would never find what was on his phone led to his re-arrest for downloading sexually violent images and child abuse material.

The man, known for legal reasons as SLD, spent almost two-thirds of his life in jail after, at age 13, he abducted and fatally stabbed his three-year-old neighbour Courtney Morley-Clarke on the NSW Central Coast in 2001.

Upon his release in 2023, he was subject to a range of strict conditions enforced by community corrections officers tasked with supervising the institutionalised man and protecting the community.

On March 20, 2025, he told supervising officers he had been breaching these conditions.

‘Good luck finding anything I do on the phone,’ he said during a supervised visit to an Optus shop.

On two occasions about a week later, he bragged about being able to delete his internet activity via the dark web, and wanting to access dating sites so he could lose his virginity.

These details come from court documents seen by AAP on Tuesday after the now 39-year-old pleaded guilty to five counts of breaching his supervisory orders and two charges relating to child abuse material.

While free in the community, he had been barred from using social networking services or dating sites without prior approval.

He was also only permitted to view sexually explicit material on a single pornographic website but was told not to watch anything involving sexual violence or cruelty towards women or children.

During a subsequent review of his phone, NSW Police found he had breached these conditions.

He was then arrested in April 2025.

Examining his phone, officers found one image of a five-year-old girl naked from the waist down.

They also located 43 images downloaded onto his device showing women in sexually violent situations, including being tied up, looking scared or in pain, and having hands placed over their mouths.

One image was titled ‘the raped virgin’, court documents reveal.

The killer also searched for sexually violent material online, including viewing one video claiming to be of a drugged woman raped in a hotel.

He tried to look for child abuse material by searching for terms like ‘real child rape’ on explicit websites.

He further breached his supervisory conditions by using a fake name to create a Facebook profile and chat with members of the public.

The 39-year-old will be sentenced at Campbelltown District Court in June.

He has already been convicted of a separate breach of his conditions when he approached a mother and her partially undressed child at a beach in Wollongong in October 2023.

He was handed an 18-month jail term and was released in March 2025, weeks before his latest arrest.

The killer has tried to overturn his conviction for that matter in the NSW Court of Criminal Appeal with a judgment due on Wednesday.

He only recently offered a motive for murdering Courtney: to exact revenge for purported bullying by her brother.
