The brother of Bali Nine member Andrew Chan says the family still holds hope his life will be spared despite assurances from the Indonesian government that he will be executed within weeks.
Speaking from Indonesia on Wednesday morning, Michael Chan admitted a planned challenge in the State Administrative Court of the presidential decree that denied his brother and Myuran Sukumaran clemency was "clutching at straws".
"I think anything at this stage that we think is going to help, we'll go ahead and do what we think is best," he told Fairfax Radio.
"There's no right or wrong at the moment - we're just clutching at straws at the moment.
"We're at the brink of there's nothing else to do for the boys."
Indonesia's attorney-general HM Prasetyo has indicated he will not wait for Chan and Sukumaran's lawyers to launch the new challenge of their death penalties before setting a date for their executions for drug offences.
Mr Chan said the family never knew whether their last visit to the prison would be the last, but they were not losing hope.
"Every time you leave there ... you think is it the last visit you're going to get before it happens, and you live with that going through your mind every second of the day," he said.
"It's tough but I think there is a glimmer of hope.
"It's very, very bleak, don't get me wrong, but we've just got to carry on the day-to-day fighting for the two boys and we will do that until the very end."
He said hearing members of the public say his brother was getting what he deserved was "heartbreaking".
"At the end of the day human nature is you're going to have two sides to everything," he said.
"Before people make that blanket decision about the boys I encourage them to go out there and look at what those boys have done in the last 10 years to reform themselves and say they're sorry."
