The Bali Nine leaders Myuran Sukumaran and Andrew Chan, convicted for drug trafficking in Indonesia, were moved to Nusakambangan Island Wednesday ahead of their scheduled executions this week.
The men have all but exhausted legal appeals and the new Indonesia President Joko Widodo has rejected calls for clemency.
Sukumaran and Chan were convicted in 2006 for leading a group of Australian drug mules who became known as the "Bali Nine".
