FYI, below is a summary of using the online application
visitor visa subclass 600, Indonesia citizen
recently introduced in 2017 for Indonesians, it does not allow for provision of important information. for example, in this case, the applicant has:
Employment: a medical professional in hospitals and clinics for over 20 years. Recently resigned from a private hospital in order to take an extended holiday, as there is no such "long service leave" in Indonesia.
Family: has 2 children, but due to the Indonesian law, after divorce, females return to the parents family register, and children remain on the ex-husbands family register, which is not accessible.
the online form does not provide a facility to state this important information
without the aforementioned critical information, highly-speculative, dogmatic, population-based presumptions about the applicant are made
as such, the visa was refused. cost A$140, non refundable
