A warning has been issued to Australian travellers following a report by the Indonesian Government showing many of the nation's airlines have met only minimal civil aviation safety standards. The warning by Australia's Department of Foreign Affairs comes in the wake of the March 7 Garuda Indonesia airliner crash in Yogyakarta which killed 21 people, including five Australians.

Among the Indonesian airlines to be given three months to improve their standards are Metro Batavia, Kartika Airlines, Trans Wisata Air and AdamSky Connection Airlines. If they fail to improve they will face further sanctions and another warning by the Indonesian Government. If that is ignored, the airlines could have their licences revoked.
