Four Australian inmates at Bali's Kerobokan prison, including convicted drug smuggler Lamar Aaron Ahchee and the individuals known as the 'Bali Three,' have been denied sentence reductions and placed in isolation after prison officers discovered them in possession of mobile phones. The discovery led to the inmates being added to a "Register F list," which records rule violations.

Approximately 1,041 inmates at the Kerobokan prison, which has a capacity of 300, had their sentences reduced for good behavior on Indonesia's Independence Day. However, Ahchee, Mevlut Coskun, Paea I Middlemore Tupou, and Darcy Jenson were excluded from this clemency.

According to Kerobokan Prison Governor Tunggul Buwono, the 'Bali Three' were found with a phone between May and June, while Ahchee's mobile was discovered on August 9. All four men have been subjected to a 12-day isolation period, during which they will not receive visits or mail. "They could not get remission (for their sentences) as they violated the rules," Buwono stated.

Their status will be re-evaluated every six months, and they may be eligible for sentence reductions in the future if no further violations occur.

The 'Bali Three' – Coskun, Tupou, and Jenson – were convicted of the 2025 fatal shooting of Melbourne man Zivan Radmanovic, 32, at a villa in Munggu. They testified that they were hired to collect a debt from another man staying at the villa who allegedly had ties to Melbourne's underworld. Jenson was sentenced to 18 years, Tupou to 17 years, and Coskun to 16 years, all avoiding the death penalty.

Ahchee was sentenced to 12 years for drug trafficking after being arrested last year with packages containing cocaine hidden in Lindt chocolates. His sentence was previously reduced to nine years in January by the Bali High Court, though he must still pay a fine of two billion Indonesian Rupiah or face an additional six months in prison.
