The ombudsman’s report examined the July episodes “Cocaine Nation” and “Meth Highway,” both fronted by former Four Corners reporter Mahmood Fazal, and found they fell short on accuracy, fair dealing and independence, citing a “culture that favoured limiting knowledge about sources” and inadequate fact‑checking.

Key failures included the program’s reliance on an anonymous source identified only as “Jason” without reasonable verification of his claims, and the use of former biker Benjamin Aitken – first portrayed as a recovering drug dealer and later as a meth cook named Brendan – without independent confirmation of his identity.

The report also highlighted that a security sweeper shown on‑screen, later linked to Aitken, was presented in disguise without proper approval, breaching standards for fair and honest dealing, and that Fazal did not disclose his personal relationship with Aitken, misleading the audience.

Fazal has rejected the findings, saying on social media that his stories passed the program’s standard editorial checks and that he feels “attacked” by the investigation, while Aitken has not commented on the allegations.

Following the ombudsman’s findings, the ABC removed both episodes in July and later pulled a third Fazal‑led Four Corners story along with several pieces from the investigative audio program Background Briefing. The broadcaster accepted all recommendations, including stricter rules on anonymous sources, enhanced fact‑checking procedures and clearer approval pathways for high‑risk stories.

The scandal has coincided with a broader shake‑up at Four Corners: senior staff including executive producer Matthew Carney, head of investigations Jo Puccini, news director Justin Stevens and managing director David Anderson have all departed, and new boss Joel Tozer has already overhauled the program’s standards.

The ombudsman called for a further investigation into the use of anonymous sources across Four Corners and for training staff on balancing legal and editorial risk, underscoring the potential damage to public trust when editorial safeguards break down.
