It’s a minimum 1 year visa right?
So stay 5-6 months in one country and then move on to another country, try to get a 1 year visa there or just maximize the 90 day Schengen limit?
The visa we had was strange, we could stay 6 months but not contiguous, 3 months at a time. It was an ESTA and free, so no need to send off passport to Australian embassy. Worked fine for us as we had a week in Vanuatu out of Brisbane, returning and resetting the clock on the visa. We also took a 2 week cruise from Sydney to New Zealand. The visa was on our British passport even though we flew out from the USA where we were living at the time.
