Condemned Bali Nine drug smuggler Myuran Sukumaran has pledged to stare down the Indonesian firing squad who will drag him to a jungle clearing and kill him shortly after midnight Wednesday. That's according close supporter and artist Ben Quilty, who has taken to the airwaves in a desperate final bid to stop Sukumaran and fellow Australian inmate Andrew Chan's execution. 'Myuran always said to me he would never take this lying down,' Mr Quilty told Radio 2GB. 'That he would stare them down, that no-one would cover his eyes, that he would face it with dignity.' As a 'realistic' Mr Quilty pledged to fight the death penalty 'with everything I have for the rest of my life', the Australian duo selected the spiritual advisers who will accompany them to their execution.

The Chan and Sukumaran families took a boat from Cilacap to the island of Nusakambangan on Monday morning for some of their last hours with their loved ones. They initially left the Cilicap port followed by Australia's consul-general to Bali, Majell Hind, and lawyer Julian McMahon after it was believed they were told the visitation rules had changed. The families have now received notice they will be required to make their final goodbyes on Tuesday afternoon, around 2pm local time. The Australians will be executed just after the stroke of midnight local time on Wednesday (3am AEST). Chan and Sukumaran both refused to sign their execution warrants when they were given 72 hours notice of their deaths during official proceedings on Saturday. The pair said they believed it would be unjust to kill them. Lawyer Julian McMahon carries a self-portrait painted by Australian death row prisoner Myuran Sukumaran .

As for Sukumaran, he has asked for as much time to paint as possible. Mr Quilty said he was confident 'Myu' will face death with 'strength and dignity'. 'He always said to me he's made terrible mistakes. I think he's forgiven himself for the horror of what he did, the crime of what he did.

The families have now received notice they will be required to make their final goodbyes to Chan and Sukumaran on Tuesday afternoon, around 2pm local time . Chan and Sukumaran both refused to sign their execution warrants when they were given 72 hours notice of their deaths during official proceedings on Saturday . 'But he has never been able to forgive himself for what he put his mum through, and his little sister, and his little brother. 'He will face it with strength and dignity. I know that about him. Because he won't want his mother to think he's a weeping mess at the end. 'He'll want his mum to think he's brave and strong and dignified. 'And she should be proud of the man he has become.' Bribery claims around the death sentences of Myuran Sukumaran and Andrew Chan must be investigated urgently as the pair await their execution within days, their lawyer is arguing. Muhammad Rifan, the lawyer who represented the Bali Nine pair when they were sentenced to death in 2006, has told Fairfax Media judges asked for more than $130,000 for a lighter sentence. Mr Rifan raised the claims months ago - without putting a sum on the bribe - and the men's current lawyer, Todung Mulya Lubis, has already lodged a complaint with the judicial commission, which appears to have stalled. Mr Lubis says the commission has an obligation to finish its probe and it's not too late to stop the firing squad, which is set for Tuesday. 'We appeal to the attorney-general, we appeal to the president in the name of due process of law, in the name of fairness and justice, not to do the executions,' he said. 'This is not an act of (a) desperado, this is a demand for justice.' Mr Lubis says claims the men face execution because of a corrupt system must be urgently investigated. 'I know that we are counting the hours,' Mr Lubis told reporters at Cilacap before visiting the Australians. 'I know that we've done everything possible under our legal systems. 'But Sukumaran and Chan still feel there's something wrong with all these legal proceedings, especially at the district court in Bali.'
