The Australian government has re-issued travel warnings to Indonesia for its citizens over concern of reprisals in the wake of the executions.
A brother of two of the condemned men arrived hours ahead of the executions at at Nusakambangan island prison, off the coast of Java. Indonesia's state run Antara news agency said the brother, Ali Fauzi, will be allowed to bathe, shroud and pray over his brothers' bodies in preparation for burial.
A makeshift helicopter landing pad had been set up at the village of two of the bombers last week to deliver their bodies.
The convicted bombers have warned that there will be retaliation by other Islamist militants if they are executed.
The suicide bombers who carried out the attacks were members of the regional terrorist group Jemaah Islamiyah.
