Bali Nine member Renae Lawrence is set to be released on November 21, media reports say.
Ms Lawrence was sentenced to 20 years in jail for her role in the notorious 2005 drug smuggling operation, however her sentence was reduced last year.
Network Ten reported on Monday an Indonesian official confirmed plans were under way to release Ms Lawrence, but logistics were still being worked out with Australian diplomats.
Australia's Foreign Affairs department would not confirm whether the reports were accurate.
"The Department of Foreign Affairs and Trade continues to provide consular assistance to an Australian woman detained in Bali, in accordance with the consular services charter," the department said in a statement.
"Due to our privacy obligations we will not provide further details."
In August 2017 Lawrence had six months taken off her sentence, paving the way for her to be potentially released in 2018.
Speaking through an interpreter, Bali's head of Board Corrections, I Made Badra, told Ten News his team had been working with the Australian consulate on the logistics of Lawrence's release.
"On the day of her release, we'll take her to Denpasar Immigration for her passport and plane ticket with her status of deportation," he told Ten News.
Lawrence was sentenced to 20 years in jail after she was caught in 2005 with 2.6kg of heroin on her body.
The Bali Nine ringleaders, Andrew Chan and Myuran Sukumaran, were executed by firing squad in 2015.
