Convicted Australian drug smugglers Shapelle Corby and Renae Lawrence have not been granted a Christmas reduction in their jail sentence in Bali.

Corby, who is from the Gold Coast, is serving a 20-year jail term at Bali's Kerobokan Prison.

She was jailed after Indonesian authorities found more than four kilograms of marijuana in her luggage at a Bali airport in 2004.

Lawrence is serving a 20-year jail sentence for her role in the failed Bali Nine plot.

The prison governor recommended cutting their sentences by six weeks for Christmas.

But their names are not among the 36 prisoners whose remissions have been announced today.

Their remissions are expected to be announced in the coming weeks.

Both Corby and Lawrence have received sentence cuts in the past, including in August as part of Indonesia's Independence Day celebrations.
