Parents of Australian citizens, permanent residents or eligible New Zealand citizens may be eligible for the grant of multiple entry visas with a maximum stay of 12 months with maximum validity periods of up to:
three years for parents outside Australia who have
had a previous Australian visa and complied with the conditions; and
have not applied for a Parent visa; or
have applied for a Parent visa (subclass 103) but are not yet in the Parent visa queue
These longer stay and validity visas are not available to people who apply in Australia.
In addition to meeting all other Tourist visa requirements, you will need to:
hold health insurance to cover any healthcare costs during your stay
not stay in Australia for more than 12 months in any 18 month period. (Like all tourists, parents granted Tourist visas are expected to maintain extended periods of absence between visits to Australia).
