The Bali nine prisoners Andrew Chan and Myuran Sukumaran have begun their journey from Kerobokan prison to Nusakambangan island where they are set to be executed by firing squad.
Where are Chan and Sukumaran being taken?
Known as the Alcatraz of Indonesia, Nusakambangan island in Central Java contains maximum-security prisons holding convicted terrorists, murderers, drug dealers and political dissidents.
About 2000 criminals - many wearing prison garbs in shades of blue - are believed to be held in the network of seven high-walled prisons, first built by Dutch colonists in 1908.
When will the execution date be announced?
The prisoners will be given 72 hours' notice of their execution time. Indonesia's attorney-general HM Prasetyo said it would take place "ASAP".
The killing of a previous group of prisoners was delayed by weather problems, journalists masquerading as fishermen to try and access the island and confusion over the religion of those condemned.
What does the execution involve?
Death row inmates are blindfolded, asked to stand, sit or kneel, and simultaneously fired upon by 12 executioners aiming for their chests. Chan and Sukumaran are set to be killed alongside another eight drug felons, which means a total firing squad of 120, drawn from Indonesia's paramilitary forces.
If the prisoner is still breathing, the commander will shoot him or her point-blank in the head.
Channel Nine has released pictures of what it claims to be the wall victims will be lined up against.
Can the prisoners see their families while on the island?
Chan and Sukumaran will be allowed to meet their families and lawyers and receive comfort from religious figures.
Chan's brother Michael and Sukumaran's mother Raji visited the pair on Tuesday but left the penitentiary before news emerged of the timing of their transfer. Other family members are expected to come over from Australia soon.
On Wednesday morning, Andrew Chan's brother Michael was frantically arranging a flight to Cilacap, the port town near Nusakambangan.
Are there any legal options left?
Todung Mulya Lubis, the lawyer representing Chan and Sukumaran, has pleaded with Indonesian authorities to "please wait" before executing the pair until all of their legal avenues have been exhausted.
In a statement on Tuesday, lawyers said the men had challenged the dismissal to their appeal in the Jakarta State Administrative Court on Monday.
Secondly, they had submitted a report to the Judicial Commission on February 13 alleging violations of judicial conduct and ethics.
Indonesia's attorney-general Prasetyo said on Monday that legal appeals pending for Chan and Sukumaran would not have any impact on the executions.
What is the government doing?
Communication between Indonesia and Australia over details of the men's execution seems to have broken down, with no official confirmation of the transfer.
Foreign Minister Julie Bishop said she was "utterly dismayed" to learn the Australians were being moved without all of their legal avenues having been exhausted. Prime Minister Tony Abbott said he still held out hope for a reprieve, and continued to make representations to the Indonesian government.
Who are the other prisoners set to be killed alongside the Bali nine members?
They are Mary Jane Fiesta Veloso (Philippines), Serge Areski Atlaoui (France), Martin Anderson alias Belo (Ghana), Raheem Agbaje Salami (Nigeria), Rodrigo Gularte (Brazil), Zainal Abidin (Indonesia), Silvester Obiekwe (Nigeria) and Okwudili Ayotanze (Nigeria). Read more about their stories here.
