If you are issued a permanent visa and become a resident of South Australia, you must obtain a South Australian driver's licence within three months and you may be required to surrender your overseas driver's licence. Once you are issued with a South Australian learner's permit or driver's licence, your overseas licence is invalid.
Is this 3 months peiod after first landing (visa validating visit) or after you land for settling permanently. Any body sure about this time period?
