Bali's chief prosecutor says he plans to transfer two Australian drug smugglers out of their Bali prison in the next 48 hours in preparation for their executions.

Momock Bambang Samiarso is charged with the responsibility of transferring Andrew Chan and Myuran Sukumaran to an island prison off Java to face a firing squad.

So far all plans Indonesian officials have announced for the executions have been delayed.

The two Bali Nine members were due to be taken away to the island last month before the move was postponed.

Mr Momock now says he has an order to transfer them this week, and plans to do so tonight or tomorrow night.

The elite police unit BRIMOB, which will handle security, and the prison managers are on standby for when the order comes through.

Lawyers for Chan and Sukumaran are still attempting a legal appeal, but the government was effectively ignoring that, saying nothing could stop the executions.

President Joko Widodo has again lashed out at foreign intervention over the death penalty in Indonesia.

Mr Widodo warned a room full of high school students about the dangers of drugs and reiterated his commitment to show no mercy to drug offenders.

"About drugs, please be careful. Now there are more or less 50 people from our generation who die because of drugs, 50 per day," he said.

Those figures are disputed, but the president has been using them to justify his tough line on drugs and he rallied students for support.

"Do you agree drug dealers should be punished to death?" he asked the students.

"Agree!" they replied.

A respected local newspaper, Kompas, has published a survey in which 75 per cent of respondents supported the president's stance on the death penalty and for refusing to back down, despite pressure from foreign countries.

Those who conducted the survey insisted their methodology had a 3.8 per cent margin of error, but they only contacted 1,000 people in 12 cities and only 652 people agreed to be polled.

The survey was hardly representative of Indonesia's 250 million citizens, but local media has been promoting the government's so-called war on drugs and over the past decade support for the death penalty has sat around 70 per cent.

Meanwhile, a woman was seen throwing balloons filled with a red-coloured substance at the Indonesian Consulate in Sydney last night.

Australian police said they were searching for the woman after some of the balloons burst, splattering the red substance out the front of the building in Maroubra.
