Bali Nine member Renae Lawrence could have her sentence cut by nine months for good behaviour, as part of Indonesia's Independence Day celebrations.
This year, well-behaved prisoners have also been recommended for a further reduction to mark another decade of independence. This year is Indonesia's 70th anniversary.
Lawrence, 37, was sentenced to 20 years' jail for her part in the 2004 Bali Nine heroin smuggling plot, and is the only member of the group eligible to receive time off her sentence.
The two men deemed "ringleaders" of the group - Myuran Sukumaran and Andrew Chan - were executed in April, and the other members are serving life in other Bali and Java jails.
Kerobokan Prison governor Sudjonggo says Kiwi Antony de Malmanche, who was jailed in June for 15 years for a drug smuggling crime, has also been recommended for a sentence reduction.
"While he's not eligible for the decade remission, he's suggested for three months off," he said.
Also recommended for a three-month reduction was Australian Edward Norman Myatt, who was jailed for eight years in 2012 for smuggling capsules of hashish and methamphetamine into Bali.
