The Bali duo are being transferred to Nusakambangan island, ahead of their execution.

Update:

Bali Nine inmates Andrew Chan and Myuran Sukumaran are en route to Nusakambangan island, where they will be executed.

Two armoured vehicles have now left the Kerobokan prison with Andrew Chan and Myuran Sukumaran, ABC News reports.

The ABC understands the Bali Nine duo are to be moved from their prison to the Indonesian island of Nusakambangan this morning, but the date of their executions is yet to be decided.

Senior security and Indonesian justice sources have told the ABC it is due to happen this morning, with two saying that it will be around 6:00am (local time).

If this latest plan runs to schedule, security personnel will arrive at Kerobokan prison to take custody of Andrew Chan and Myuran Sukumaran.

Under heavy guard they will then be transferred to Nusakambangan island prison, off the coast of Java, where their executions are to take place.

Prison officials have been told to get ready to discharge the two Australians.

“We have prepared the administrative part of it. We keep checking and rechecking, so there won’t be any mistakes in the dots and commas,” prison governor Sujonggo said.

“Our job is just that, to prepare the people, papers, and that’s it. And they all have to match.”

The rest will be up to prosecutors acting under the authority of attorney-general Muhammad Prasteyo and the police and military personnel involved in the transfer.

Bali’s chief prosecutor, Momock Bambang Samiarso, told reporters on Tuesday that within two days he planned to send the pair to the island where they were due to be executed.

Mr Prasetyo, who is in charge of the executions, said on Tuesday afternoon that he was still waiting for a report on preparations at the island prison in the next couple of days.

He said preparations were 95 per cent complete.

Mr Prasteyo has to give Chan and Sukumaran 72 hours’ notice before the men can face a firing squad.

So far, all plans Indonesian officials have announced for the executions have been delayed.

The two Bali Nine members were due to be taken away to the island last month before the move was postponed.

Federal politicians voice dismay at transfer announcement

Foreign Minister Julie Bishop said the news that Chan and Sukumaran would be transferred so soon was devastating.

“I am dismayed by reports that Andrew and Myuran are to be transferred by Indonesian authorities for their execution,” she said in a statement.

“Give their rehabilitation, it is callous for these executions to proceed.”

Former attorney-general Philip Ruddock said Australia would continue to seek a stay of execution for Chan and Sukumaran.

“It would appear to suggest that the Indonesians are progressing to a situation where they will be executed, I think that is clear, but that doesn’t mean we should stop putting our representations [forward] and I know the Foreign Minister’s been very active in relation to the matter,” Mr Ruddock said.

Federal politicians have reformed the Parliamentarians Against the Death Penalty Group, which was disbanded at the last election, in a show of support for the Bali Nine pair.

“I don’t think it would, in that sense, have made an immediate difference in relation to the convictions that they suffered, the death penalty that was imposed, but I’ve wanted to ensure that we have a continuing role in these matters,” Mr Ruddock said.

Lawyers for Chan and Sukumaran are still attempting a legal appeal but the government is effectively ignoring that, saying nothing could stop the executions.

Indonesian president Joko Widodo reiterated he had to take a hard line on drugs, saying up to 50 people a day die from drug-related deaths.

“About drugs, please be careful. Now there are more or less 50 people from our generation who die because of drugs, 50 per day,” he warned a room full of high school students.

Those figures are disputed, but the coordinating political, legal and security affairs minister, Tedjo Edhy Purdijatno, has been with the president at a ceremony and said he was sure of the figures.
