The men were the last Australians still imprisoned in Indonesia for trying to smuggle heroin in 2005, in a case that became a diplomatic flashpoint between the countries.

Australia's government said on Sunday that five members of the "Bali Nine" drug ring have returned from Indonesia, after diplomatic efforts between the countries this month to strike a repatriation deal.

The five remaining members of the so-called Bali Nine drug-smuggling ring have returned to Australia after serving nearly two decades in Indonesian prisons.
