Dear Friend,
You don't have to have an Indonesian's CPL?ATPL in order to fly commercially in Indonesia. Your OZ's licence is good enough. All you have to do is get a company in Indonesia to sponsor your employment, submit an application to INA CAA for licence validation and sit for the local airlaw papers. You will be given the 'Certificate of Validation' and it remains valid as long as your medical is valid and you are working with the same company throughout.
Hope the above info will help. It applies to all ICAO contracting states in accordance with Chicago Convention (forgot the year).
Happy Flying.
