On Saturday, the Bali Nine duo and other death row inmates were given 72 hours notice ahead of their deaths, when prosecutors were called to Nusakambangan to finalise the execution papers.
When asked to sign his papers, Sukumaran refused and told officials he believed he had been rehabilitated and that he had been doing positive work in prison.
'When he received the 72 hours notice he remained dignified and peaceful. He spoke with courtesy and clarity to a hushed room explaining why he felt to proceed to execution was unjust,' the pair's lawyer Julian McMahon told News Corp.
Mr McMahon said Chan also refused to sign the papers, explaining that he had been rehabilitated in the 10 years he had spent in prison.
'I have helped other inmates as much as I can and I still do and that's not me talking, you will hear that from a lot of people, the ones I have helped,' Chan said.
The pair were also asked to outline their last requests, with Chan asking for extra time in church to pray with his family and Sukumaran asking to be able to paint as much as possible before his death.
Sukumaran's mother Raji and sister Brintha visited him on Sunday, making the sad journey with Chan's mother Helen, brother Michael and fiancee Feby Herewila and other friends.
Funeral director Suhendra Putro, on Sunday was busily stencilling crosses and putting finishing touches to writing the names of the Christian victims and the dates of their deaths, reports The Herald Sun.
As well as the names of the two Australians, the names of Brazilian national Rodrigo Gularte, Nigerian, Okwudili Ayotanze, and Mary Jane Fiesta Veloso of the Philippines, were also written in white on the wooden crosses. The date '29.04.15' was also written in white ink and the letters 'RIP'.
The condemned inmates will be killed after the stroke of midnight on Tuesday night-Wednesday morning.
This was further confirmed by Utomo Karim, the lawyer for a Nigerian prisoner facing the firing squad, and also in a letter sent to Filipina maid Veloso.
'Each convict on death row was called in one by one, for between 30 minutes to one hour, it varied,' Mr Karim said.
'My client (Nigerian Raheem Agbaje Salami) was notified of the day of the execution, it will be (just after midnight on) Tuesday night.'
Mr Karim added that the six others were also told the countdown to their execution had started.
My client has received a notification letter that in 72 hours there will be an execution,' said Mr Karim.
'Families will have time to visit Nusakambangan until Tuesday 2pm ... it will be carried out on later on Tuesday after midnight.'
This comes amid reports the judges who sentenced Chan and Sukumaran to death were allegedly willing to give them a more lenient sentence in return for bribes of more than $130,000, but later changed their minds and demanded more money after senior government figures ordered them to impose the death penalty.
Bali-based lawyer Muhammad Rifan said he had meetings with judges, who allegedly started demanding more money to deliver a prison sentence of 20 years or less saying it was 'risky', Fairfax reported.
Mr Rifan said he believed the judges were bluffing, a mistake he now fears will turn out to be fatal after the death penalty was handed down.
Foreign Minister Julie Bishop on Monday said a judicial commission should be allowed to complete its investigation ahead of Chan and Sukumaran's executions, following the new allegations of corruption.
Ms Bishop say Sukumaran and Chan should also be able to complete action they are taking in the constitutional court.
'I've asked Foreign Minister (Retno) Marsudi that no action be taken in relation to those executions until these legal processes have been determined,' she told ABC radio on Monday.
Her parliamentary secretary Steve Ciobo said Australians wanted to know the whole process had been free from the taint of corruption.
Prime Minister Tony Abbott also has made a last-minute plea by writing to Indonesian president Joko Widodo asking him to spare the lives of Sukumaran and Chan.
'This is not in the best interests of Indonesia, let alone the best interests of the young Australians concerned,' he told reporters in France.
Chinthu Sukumaran said his brother had made peace with the situation, 'but he and we all feel that this is a grave injustice and it did not have to be this way and it still doesn't have to be this way', he told reporters.
'We ask the president to please use his powers to intervene and save their lives.'
Michael Chan said mercy must be part of Indonesia's legal system and implored the president for his mercy.
'He's the only one that can stop it and it's not too late to do so,' he said.
Prime Minister Tony Abbott is due to meet French leader Francios Hollande on Monday, having pledged to work together to stop the executions, while UN Secretary General Ban Ki-Moon has added his voice to global calls to halt the execution plans.
But Indonesia's President Joko Widodo appears to have closed his ears to calls for mercy from the families and the world.
Before leaving for a summit in Malaysia on Sunday, the president known as Jokowi told reporters: 'I've already talked several times about it, I don't want to talk about it again,' news website Rappler reported.
The men were issued with a 72-hour deadline on Saturday to face a 12-man firing squad, and both the Australian government and their families have pleaded with Indonesia to spare the convicted drug smugglers.
In previously unreleased interviews, Chan has told of the anguish he feels for his family, saying that it is not right that his mother will have to bury him.
Despite his impending execution, Sukumaran has not stopped painting, with the pair's Australian lawyer Julian McMahon coming off a boat from the island clutching a small collection of eerie new self-portraits.
In a brief interview on arriving at Wijaya Pura port in Cilacap, Chan's brother, Michael, and Sukumaran's brother, Chintu, made more pleas to authorities to spare their brothers' lives.
'The two boys are holding up pretty well. Somewhere in the legal system there's got to be mercy. Please ask the (Indonesian) Prime Minister to show mercy,' Michael Chan said.
In interviews that have surfaced for the first time, the Australians spoke about facing the death penalty, but also of hope and their genuine efforts at rehabilitation in 2011.
The emergence of the interviews comes as their families have been seen making the journey over to Nusakambangan, Indonesia's 'Death Island', to spend their final hours with the pair.
Sukuraman's mother Raji and siblings Brintha and Chunthu were among those to visit him on Sunday.
Joining them were Chan's mother Helen, brother Michael and fiance Feby, among other friends.
It is unclear how many of the 10 prisoners Indonesia's has readied for execution will face the firing squad, with reports Frenchman Serge Atlaoui has been granted a reprieve.
Chan's comments from four years ago reflected the grief seen on his loved ones' faces as they made one of their final journeys to see the convicted drug smugglers.
Chan told AAP their imprisonment had 'obviously affected our families the most'.
'Imagine your mother, or you know, your father picking up that telephone call,' he said.
'It's heartbreaking. It's obviously harder on them than it is on yourself.
'You obviously look at yourself and you say to yourself, "I've really screwed up big time".
'It's not right you know. A mother's not supposed to bury their kid. Obviously a kid is supposed to bury their mother.'
At the time, Chan and Sukumaran were about to lodge their bids for clemency.
They spoke about making mistakes and paying for them.
'Everyone makes mistakes in life,' Chan said.
'No one's perfect. Yeah, we screwed up big time, and you know, we're obviously paying the price for it right now.
'The death penalty. You can think about it, you can let it lay within your mind but we choose to continue doing what we're doing.'
Sukumaran said in prison 'you have a lot of time to reflect on all the stupid things you've done'.
'You don't see what you're doing is really that bad,' he said.
'Working with all these people, like inside here teaching ... you get something out of it. I think that makes you a stronger person as well.'
Despite testimonials to their rehabilitation behind bars from prison governors to politicians, academics and Australian artist Ben Quilty, repeated legal appeals and calls for a reprieve have failed.
Chan and Sukumaran, convicted in 2005 for their role in a plot to smuggle 8.3kg of heroin from Bali to Australia, were given the official 72 hours notice on Saturday that means they could face the firing squad on Tuesday.
Although the date has not been set, Indonesian authorities said the pair will be among a group of death-row prisoners executed this week.
Another two paintings were signed: 'Our new prison. A Bad Sleep Last Night' and 'A strange day'. They were dated April 25 and April 24 respectively.
It has also been revealed the undertaker in the port of Cilacap has been asked by the police chief to prepare the coffins for transport to the island, which will happen 'soon'.
Foreign Affairs Minister Julie Bishop confirmed the executions will be scheduled imminently on Saturday, but called on the Indonesian government to show mercy to the pair.
'The thoughts and prayers of many Australians would be with Mr Chan and Mr Sukumaran,' a statement from Ms Bishop read.
'I spoke to Mr Sukumaran's mother Raji yesterday and assured her the government would continue to seek clemency from Indonesian President Widodo for both men.
'Nothing can be gained and much will be lost if these two young Australians are executed. I again respectfully call on the President of Indonesia to reconsider his refusal to grant clemency.
'It is not too late for a change of heart.
'Australia asks no more of Indonesia than it has asked of other nations where Indonesian citizens on death row have been granted clemency including for serious drug offences.'
Last ditch efforts to save the pair have also been launched by not-for-profit organisations, such as Amnesty International.
Thousands of flowers will be used to spell out the words KeepHopeAlive at a reserve overlooking Sydney Harbour in an appeal for Chan and Sukuraman.
Amnesty International says the floral message will be displayed from Monday at Blues Point Reserve.
'Today in Indonesia, up to nine people - including Australians Andrew Chan and Myuran Sukumaran - face imminent execution in as little as 72 hours,' Amnesty said in a statement.
'More than 140 countries around the world have now abolished the death penalty for good. It's not too late for Indonesia to join them.'
Members of the public are encouraged to contribute to the appeal by purchasing flowers from Amnesty's website.
Earlier, Australian embassy officials were called to Cilacap, the port town closest to Nusakambangan where the Bali Nine pair are now jailed, for a meeting about Indonesia's execution plans.
'I fear the worst,' Ms Bishop told reporters in Brussels. 'I fear that Indonesia will seek to proceed with the execution of the two Australian citizens.
'I am deeply and profoundly concerned by this.'
Chan and Sukumaran, who were arrested over a heroin smuggling plot in 2005, can be executed 72 hours after being given notice, according to Indonesian law.
A former inmate of Kerobokan prison has told of how he was baptised by Bali Nine drug smuggler Andrew Chan who helped him kick his 20-year drug addiction, told Daily Mail Australia he is heartbroken and struggling to cope with the news.
'I am really disappointed with the government and how they deal with this issue,' Matius Arif Mirdjaja said.
'It would be better to make sure justice rather than execute, better to secure rights rather than take them.
'It's definitely really hard for me to cope with this. I have to keep my faith.'
Mirdjaja also accused the Indonesian government of using the executions the two Australians as a distraction.
'This is not about law enforcement - it is a tragedy presented for public consumption,' he said.
'Government have lost their mind to gain popularity by execution; they use the drugs war to hide other issues that are more serious.' Mirdjaja said he spoke with Chan and Sukumaran two weeks ago, and the two were 'good'.
'Andrew is OK, Myu starting making a sketch. But they were attacked by mosquitoes.'
The 40-year-old started a bible group with Chan inside Kerobokan prison.
Since he was released in 2013, Mirdjaja has preached at churches in south-east Asia, while trying to roll out rehabilitation programs started by the Australians to help others at 17 different prisons around Indonesia.
Filipina Mary Jane Veloso's transfer from Yogyakarta prison is considered an ominous sign for the other prisoners, after Indonesian Attorney-General H.M. Prasetyo said the 10 death-row inmates would be executed together for the sake of 'efficiency.'
News website Rappler reports the executions will take place on Tuesday.
Veloso's sister Marites told Rappler her sister called her with the news.
She had been told the date in the presence of embassy officials, hours after her family had visited, according to the website.
The embassy of the Philippines was called to the same Saturday meeting, along with France, Brazil and Nigeria, who all have citizens listed to face the firing squad.
While admitting the summons has her worried, Ms Bishop said there was still time for President Joko Widodo to show mercy towards the two rehabilitated Australian men.
'He is the leader of a great nation, a dear and close friend of Australia,' she told reporters. 'We ask that he take into account our considerations.'
Ms Bishop's office says the Foreign Minister is seeking a phone call with her Indonesian counterpart, Retno Marsudi, who was unavailable on Friday with Indonesia hosting the Asian African Conference.
Indonesian officials say the Cilicap meeting signals the beginning of the 'execution process'.
On Thursday, Indonesia's head of General Crimes sent letters to the prosecutors of all 10 prisoners and ordered preparations be made for their executions.
The lawyer for Nigerian man Raheem Salamim, who is sharing a cell block with Chan and Sukumaran on Nusakambangan, confirmed Thursday the Nigerian Embassy had also received a letter summoning officials to Cilacap.
'Based on experience from the previous execution, they're going to tell them the date for the execution,' lawyer Utomo Karim said.
Indonesian President Joko Widodo earlier confirmed the executions were 'only a matter of time'.
President Widodo told Indonesian news agency Antara while he would not interfere with the inmates' outstanding legal appeals, the executions would take place upon their conclusion.
'When it will be done is no longer a question,' he said. 'It is only awaiting the conclusion of all procedures and the legal process, which I will not interfere in. It is only a matter of time.'
In Gallipoli, Prime Minister Tony Abbott said efforts to save Chan, 31, and Sukumaran, 34, would continue.
'I guess there's always hope while there's life but obviously these are late days.'
Chan and Sukumaran's families will fly to Indonesia on Saturday and their lawyers, who have lodged a challenge with the constitutional court, are also on the way.
The Attorney-General has already suggested that a Constitutional Court challenge will not be taken into account, believing the pair have exhausted their appeals options.
Sukumaran's sister, Brintha, has pleaded for her older brother's life in a short YouTube video.
'My brother made a mistake 10 years ago and he's paid for that mistake every single day since then' she says, clutching a photo of Sukumaran as a boy.
'My family and I have also paid for this mistake as well.'
But he's become a good man after 10 years in jail, she says.
'He has taught so many Indonesian prisoners about art and how to live outside in the world and have a good and productive life,' she said.
'From the bottom of my heart, please President Widodo, have mercy on my brother.'
