Prime Minister Tony Abbott has so far been rebuffed by Indonesian President Joko Widodo in his request for a "final call" to plead for the lives of Andrew Chan and Myuran Sukumaran.
It is now more than 24 hours since Mr Abbott revealed he had requested a phone call with the Indonesian leader in response to the Bali nine pair having been moved to so-called "death island" Nusakambangan.
Mr Abbott's office said that as of just after 11am on Friday there had been no response from the presidential palace in Jakarta.
The lack of response came amid signs of deteriorating relations over the impending executions.
Foreign Minister Julie Bishop will haul in the Indonesian ambassador to explain the "degrading treatment" of Chan after tasteless pictures emerged of the condemned pair with the Bali police taken during their air transfer to Java. Treasurer Joe Hockey described the pictures as "incredibly insensitive" and "macabre".
On Friday, Mr Abbott said the pictures were "unbecoming". "I thought that they showed a lack of respect and a lack of dignity and obviously we've already protested to the Indonesian ambassador here in Canberra," he said.
Asked about the phone call request, Mr Abbott held out hope that Mr Joko would yet pick up the phone as it emerged that the executions could still be up to 10 days away.
"Look, the Indonesian system has its own processes and obviously when I put in a request, sometimes it takes a little while for that request to be acted upon," he said.
"I want to assure people that even at the 11th hour the Australian government we are doing everything we humanly can to let the Indonesian government and people know that it would be in neither in their best interests or their best values for these executions to go ahead," he said.
"I spoke to him about a week ago, I've sought a further call, I've raised this matter with him on previous occasions. He absolutely understands that while we respect Indonesia's system of justice and we want nothing but the best for Indonesia and we look forward to a strong and growing friendship in the months and years ahead. While this is all true, we deplore the death penalty, we deplore drug crime, but we deplore the death penalty, particularly for people who have been so thoroughly rehabilitated."
