Bali Nine duo's final wish honoured

Myuran Sukumaran and Andrew Chan are spending some of their final hours with family as the clock ticks down to their executions.

The Bali Nine pair was told on Saturday they will be executed on Tuesday, a moment preserved by Sukumaran who signed one of three self-portraits "72 hours just started".

His mother Raji and siblings Brintha and Chunthu were among those to visit him on Sunday, making the sad journey with Chan's mother Helen, brother Michael and fiance Feby, among other friends.

It's 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.

Sukumaran and Chan were also asked on Saturday for their last wishes, and have been granted more time with family in their final days.

Lawyers are pleading with Jakarta to respect legal proceedings that several are still pursuing, while international pressure for mercy also grows.

France has pledged to work with Australia to halt the executions, with Prime Minister Tony Abbott set to meet Francois Hollande on Monday.

Foreign Minister Julie Bishop said the government will continue to seek clemency from Indonesian President Widodo for both men.

She said the thoughts and prayers of many Australians were with the condemned pair and their families.

"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."

Chan and Sukumaran's lawyers have lodged a challenge with the constitutional court but the attorney-general doesn't acknowledge it, arguing the pair have exhausted their appeals.

But his office is yet to respond to moves by lawyers for Filipina Mary Jane Veloso, who filed a second request for a judicial review late on Friday.

Indonesian Zainal Abidin has an appeal before the courts due to be decided on Monday but has been moved in preparation for execution, as if the result was pre-determined.

Atlaoui apparently won a reprieve based on an administrative matter.

UN Secretary General Ban Ki-Moon has added his voice to global calls for Indonesia to halt its execution plans.

"The Secretary General urges President Joko Widodo to urgently consider declaring a moratorium on capital punishment in Indonesia, with a view toward abolition," a spokesman for Ban said.

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."

Prime Minister Tony Abbott, who is set to discuss the executions with French leader Francois Hollande on Monday, called Chan, 31, and Sukumaran, 34, "well and truly reformed characters" after their decade in prison for the foiled heroin smuggling plot.

'My brother made a mistake'

The sister of Australian drug trafficker Myuran Sukumaran issued an emotional plea for his life to be spared, appearing in a YouTube video clutching a photograph of her brother as a young boy wearing a school uniform.

"My brother made a mistake 10 years ago and he's paid for this mistake every single day since then," Brintha Sukumaran said.

"From the bottom of my heart, please President Widodo have mercy on my brother... change punishment for humanity."

The family members of Sukumaran and Andrew Chan, the other Australian facing imminent execution, were also en route to Cilacap. The pair, sentenced to death in 2006, are the ringleaders of the so-called "Bali Nine" heroin-smuggling gang.
