Fear, shock and calls for resilience have rung out in Indonesia's 10-million strong capital in the wake of a twin suicide attack that killed three police officers and left at least 11 people injured.

Australian authorities have reminded travellers of the "ongoing high threat of a terrorist attack in Indonesia", telling people to be vigilant and exercise caution when visiting the archipelago.

The busy Kampung Melayu bus terminal in eastern Jakarta was sent into chaos at around 9pm (local time) on Wednesday when two blasts are believed to have occurred.

National Police spokesman Colonel Martinus Sitompul told AAP on Thursday morning that they suspect a pressure cooker bomb was responsible for at least one of the blasts.
