So my girlfriend is currently on a Student Visa that ends in July 2019.
She enrolled for 3 short courses from January 2018 - July 2019, with each course taking approx 6 months.
She isn't going to be doing the last course because we're both going to be moving to her home country, so we are thinking of leaving next year in January, before the classes begin for the last course. Part of the reason for this is that we'd rather just save the money, as each course is $6k every 6 months.
Do immigration need to be notified that we're leaving early? Or can we just up and leave without paying the last $6k and not tell anyone?
Obviously the visa will be cancelled when she does not enrol, but we just don't want it to hurt her chances of coming back into Australia or future visas because we didn't go through a proper protocol.
