A meeting to confirm the date Andrew Chan and Myuran Sukumaran will be transferred to Nusakambangan island will not be held on Friday.
The official responsible has been called to Jakarta on an unrelated matter, a spokesman for the Bali prosecutor's office says.
The Australian pair are to be transferred from Kerobokan jail in Bali to the other island for their execution.
Foreign Minister Julie Bishop has described the situation as 'tense' as the execution of two drug smugglers looms in Indonesia.
Authorities in Indonesia are finalising plans to move Australian men Andrew Chan and Myuran Sukumaran from Bali to their execution place on a prison island off Java, and a date for the transfer will be determined on Friday.
Ms Bishop says Australians might be moved to boycott Indonesia if the executions go ahead.
'I think the Australian people will demonstrate their deep disapproval of this action, including by making decisions about where they wish to holiday,' she said.
She says the government will leave no stone unturned in its bid to secure a stay on the Bali Nine members' executions.
'Executing these two young men will not solve the drug scourge in Indonesia,' she told Fairfax radio on Friday.
'It's a very tense situation.'
Ms Bishop said she hoped Indonesia didn't underestimate the Australian public's opinion on the situation.
'I've been overwhelmed with emails and text messages, I know that people have been staging vigils and rallies,' she said.
'We're asking for clemency, we're asking for mercy for two Australian citizens who have been rehabilitated.'
Meanwhile, Archibald Prize-winning artist Ben Quilty and friend of Myuran Sukumaran says the Bali Nine pair seem to have lost hope.
Quilty arrived back in Australia after visiting the pair in Kerobokan prison.
Mr Quilty, who came to know the pair while holding art classes at the jail, says Sukumaran seemed 'broken' on Thursday.
'I think hope has gone from them now and they're just trying to work out how to cope with what's coming,' he told Fairfax radio on Friday.
Sukumaran told Quilty his room had been raided for the first time, and a lock removed from the inside of the door.
'I assume so they can come and take him when they're ready to take him,' Mr Quilty said.
'To torture him this way, emotionally torture him, and drag this process out is the most barbaric thing I've ever, ever witnessed in my life.'
Mr Quilty said Chan and Sukumaran were now focused on their families' grief.
The families of Andrew Chan and Myuran Sukumaran are visiting the men in Kerobokan jail on what may be one of their last days there.
Sukumaran's mother, Raji, has make another desperate plea for help and says she doesn't want her son murdered.
The men's Australian barrister, Julian McMahon, is also visiting the jail, along with pastor Matius Arif and other local friends of Chan.
Meanwhile, Indonesia this week announced it's stepping up efforts to save its own citizens on death row overseas.
Most are convicted drug traffickers and murderers in Saudi Arabia and Malaysia.
