"Following the fatal crash of a Lion Air plane on 29 October 2018, Australian government officials and contractors have been instructed not to fly on Lion Air or their subsidiary airlines. This decision will be reviewed when the findings of the crash investigation are clear (see Local travel). The level of our advice has not changed. Exercise a high degree of caution in Indonesia overall, including Bali. Higher levels apply in Central Sulawesi and Papua provinces."
