The Foreign Minister's bid for a Bali Nine prisoner swap has been denied.

Two Australians listed for execution in Indonesia have been given a brief reprieve, while the country’s president has confirmed Jakarta will not be taking up Australia’s offer for a prisoner swap.

Indonesia’s justice and human rights minister, Yasonna Laoly, told the ABC there would be a “short delay” to the next round of executions, which includes drug traffickers Andrew Chan and Myuran Sukumaran.

Other media have been told the delay was up to 10 days by a source the ABC understood to be senior within the ministry responsible for timing the executions.

Officials and lawyers representing foreigners on death row believed the delays might have been partly caused by unresolved legal processes involving five of the 11 people listed for the next round of executions.

Sukumaran and Chan fall into that category, with both pursuing legal appeals or challenges.

Meanwhile, Indonesia has officially rejected Australia’s prisoner swap proposal for the death row inmates, saying it did not have the legal instruments for such an arrangement.

The foreign affairs ministry confirmed that the suggestion to send three Indonesian prisoners home if Jakarta stopped its plans to execute the two Australians was not something it was considering.

Ministry spokesman Arrmanatha Nasir said the reasoning was explained in a phone call between Indonesian foreign affairs minister Retno Marsudi and her Australian counterpart Julie Bishop earlier this week.

“We understand the need for Australia to assist its citizens, but again we emphasise that such efforts should be done in a diplomatic manner, in a way that is respectful to the laws of the country – in this case the laws of Indonesia – and also respect the sovereignty of the laws in Indonesia,” Mr Nasir said.

Members of the Chan and Sukumaran families flew into Yogyakarta airport on Thursday before driving to Cilacap.

They were being supported by consular officials from the Foreign Affairs Department.

Visiting days for the prison wing are Mondays and Wednesdays, but officials and lawyers representing the two men are trying to negotiate special permission for the families to visit the men sooner.
