Myuran Sukumaran and Andrew Chan will face the firing squad on Tuesday unless Indonesia’s president has a last-minute change of heart.

The Bali Nine pair was given notice on Saturday of Indonesia’s intention to execute them in a minimum of 72 hours, during a meeting on Nusakambangan Island.

Lawyer Julian McMahon returned from the island with three self-portraits by Sukumaran – one of them dated April 25 and signed “72 hours just started”.

The Chan and Sukumaran families are making their way to Indonesia and it’s understood they will be allowed to visit the men on Sunday.

Foreign Minister Julie Bishop said the thoughts and prayers of many Australians were with them.

“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,” she said in a statement.

“I again respectfully call on the President of Indonesia to reconsider his refusal to grant clemency,” she said.

“It is not too late for a change of heart.”

A lawyer for Nigerian Raheem Salami, who is set to face the firing squad alongside Chan, Sukumaran and up to seven others, says the prisoners were told their executions would be on Tuesday.

Utomo Karim watched as they were told individually.

“Myuran, I didn’t see much,” he told reporters.

“Andrew, he’s OK. Basically, they looked tough.”

Mr Utomo believes only seven prisoners were given the news, and there may be outstanding legal issues with others who had been named among the ten to be executed.

They included Frenchman Serge Atlaoui, who has reportedly been granted a reprieve after lawyers challenged an administrative matter in his case.

Jakarta had promised to respect the prisoners’ legal challenges before setting an execution date.

However, Filipina Mary Jane Veloso has a second appeal application before the courts and Indonesian Zainal Abidin is still awaiting a decision on his.

Chan and Sukumaran have challenges before the Constitutional Court and Judicial Commission that raise questions about the sentencing and the clemency process.

Prime Minister Tony Abbott is set to discuss the executions with French leader Francois Hollande on Monday.

Mr Abbott has called Chan, 31, and Sukumaran, 34, “well and truly reformed characters” after their decade in prison for the foiled heroin smuggling plot.

‘My Brother Myu’

Myuran Sukumaran’s sister Brintha has posted online an emotional plea for the life of her brother to be saved.

“My brother is now a good man and after 10 years in prison, he has taught so many Indonesian prisoners about art and about how to live outside in the world and have a good and productive life,” she says.
