Bali Nine inmates to be transferred to execution island within 48 hours

Bali Nine death row inmates Andrew Chan and Myuran Sukumaran are set to be transferred to an island prison within the next 48 hours.

Chief prosecutor Momock Bambang Samiarso said the transfer of the pair from Kerobokan prison to the island where they will be executed by firing squad will happen today or tomorrow.

Once on the island, it is understood the pair will be given 72 hours notice prior to the executions taking place.

The timeframe for moving the men has shifted several times, as Indonesia prepares to execute 10 drug offenders - the most it has ever executed at one time.

President Joko Widodo has been contacted by leaders of various nations, including Australia, France, the Netherlands and Brazil, but has not been swayed.

Lawyers for Chan and Sukumaran were on Monday lodging an appeal against their latest court loss in the administrative court.

Some of the other eight to be executed also have future court dates.

Chan and Sukumaran's barrister Julian McMahon warned that sending them for execution before the appeals could jeopardise Indonesia's reputation as a law-respecting democracy.

"It's unthinkable that people who are having their right to life litigated in a court could at the same time be taken away from that court by powerful people, but the executive, and simply executed," he said.

But Mr Joko believes executing drug offenders is important for national sovereignty.

"Don't let anyone try to intervene in our sovereign law," he said before an audience of school students at the presidential palace on Monday.

"About the executions of drug offenders, this is our sovereign law."
