Prime Minister Tony Abbott believes photos of an Indonesian police chief posing with Andrew Chan and Myuran Sukumaran during their transfer for execution are disrespectful.
The government has lodged a complaint with the Indonesian ambassador in Canberra over the images.
"I thought they were unbecoming," Mr Abbott told reporters when asked about the images on Friday.
"They showed a lack of respect and a lack of dignity."
Mr Abbott is still waiting to hear back after his request for another telephone call with Indonesian President Joko Widodo.
The pair spoke a week ago.
"I want to assure people even at the eleventh hour Australia is doing everything we humanly can," he said.
The Australians, now positioned on the island of Nusakambangan for execution, can't be executed this week as Indonesia's Attorney-General HM Prasetyo has not signalled that their 72-hours notice period has begun.
