Indonesia's national human rights institution will stand with the families of Australians Andrew Chan and Myuran Sukumaran to demand a stay of execution for the condemned drug smugglers.
Raji Sukumaran, mother of Myuran, and other family members of the pair will travel to Jakarta on Monday to meet the National Commission on Human Rights (Komnas HAM).
Commissioner Natalius Pigai says the organisation has been pushing for the executions of six drug offenders last month to be Indonesia's last.
But with the executions of Chan, Sukumaran and others planned for this month, they continue to lobby President Joko Widodo to change his stance on the death penalty.
"We will support Myuran's mother in her aim to reject this death penalty," Mr Natalius said.
"We should work together, there's still time to annul this execution.
"Up to today, we're still working so that there's no more death penalty for such law violation."
The Australian and Indonesian lawyers of Chan, 31, and Sukumaran, 33, will announce their latest legal efforts to stay the executions at a media conference in Jakarta on Monday.
A former lawyer for the Sydney pair, Muhammad Rifan, has hinted at revelations that could aid a new appeal after meeting the men on Saturday.
He alleged there had been political and legal interference in their first trial for the 2005 heroin smuggling bid.
But Indonesia's ambassador has played down hopes of a new appeal.
Nadjib Riphat Kesoema said the pair's legal fight had reached "the highest level".
"Indonesia has notified the government of Australia that we will execute these two gentleman," he told reporters in Canberra on Sunday.
