Prominent Sydney Barrister Dies Amid Child Abuse Material Scandal

A prominent barrister from Sydney, Mark Dennis, SC, tragically took his own life amid a scandal involving child abuse material. His death occurred just weeks after the Australian Federal Police (AFP) reportedly discovered disturbing content on his phone during his return from a charity trip to South-East Asia.

Background on Mark Dennis

Mark Dennis was an established figure in the legal community. Renowned for his extensive contributions as a writer and mentor, he played a significant role in guiding young barristers. In 2020, he co-founded a charity called Reasonable Cause, aimed at providing scholarships and promoting literacy for disadvantaged youths in Cambodia.

He frequently visited Cambodia to oversee the charity’s activities, attending events with notable speakers from the legal profession.

Details of the Incident

On January 28, 2026, Dennis returned to Sydney on a flight from Cambodia. Following his arrival, officers from the Australian Federal Police and the Australian Border Force conducted a search of his luggage. During this examination, they allegedly discovered child abuse material on his mobile phone and linked devices.

As a result, Dennis faced serious charges, including possession, distribution, and importation of child abuse material. Two weeks prior to his death, he had made an appearance in court from police custody.

Death and Investigation

Mark Dennis, aged 56, was found deceased at his residence in Leichhardt by New South Wales Police. His suicide has raised concerns about the ongoing AFP investigation, which has not yet concluded. Authorities are expected to examine his overseas activities to determine if any children were ever at risk through his charity work.
