Myuran Sukumaran and Andrew Chan have spent their first night on Indonesia's "death island" and don't know how long they will wait for their executions.
The men on Wednesday left the cells at Kerobokan jail that have been their home for much of the past decade, since their arrest for the 2005 Bali Nine heroin smuggling plot.
Indonesia deployed its heaviest security for the task - more than 100 police, armoured cars and even fighter jets.
But the Australians walked calmly from their cells, thanking authorities for their care and shaking their hands before they were handcuffed.
Chan, now a Christian minister, took a Bible, and Sukumaran, an accomplished painter, took pencils and a drawing book.
They were flown to Nusakambangan, and spent Wednesday night on the island where they will meet the firing squad.
Their families are expected to arrive in Cilacap, the nearest town to the island, on Thursday, flying from Sydney and Bali.
They will be allowed to visit the men, Indonesia's Attorney-General HM Prasetyo says, but he is yet to announce a date for the executions, saying only it will be as soon as possible.
He is also reconsidering how many prisoners should be executed at one time, after planning for weeks for 10 to be shot simultaneously.
"We want to show the world that Indonesia is trying very hard to combat drugs," he said.
The prisoners will get 72 hours' notice of the executions.
There is speculation they will be this weekend, based on the executions of five people at Nusakambangan in January, which were held after midnight on a Sunday.
But Al Jazeera's Indonesia correspondent Step Vaessen on Wednesday night tweeted: "President Jokowi told me no executions this week at sidelines of interview I had with him this afternoon."
Lawyers for Chan and Sukumaran are still pursuing legal recourses and say they shouldn't be executed in the meantime.
Prime Minister Tony Abbott on Wednesday said Australians are "revolted" by the prospect of the executions.
Australia is continuing its efforts to seek clemency for the men, he said.
