I have a 3-year ban in Australia, with 1.5 years left. The reason: I thought my student visa expired in July but it expired in June, so I overstayed my visa for 1 month. I am going to New Zealand on a working holiday visa and I'm transferring from Brisbane (AUS) to NZ. Will I have any complications or can I go to NZ with no worries?
It looks like you may be okay, depending on the airport through which you are flying.
Australia's rules are listed here and, to summarize them:
- You will need to clear customs and immigration if you are flying through Perth. Since you're inadmissible, this wouldn't work.
- Gold Coast airport has some complications that may make it impossible.
- Cairns and Sydney are okay, as long as you do not need to stay overnight.
- Adelaide will only work if you depart on the same aircraft from which you arrived, or your airline makes prior arrangements with the airport.
Note also that your citizenship may affect this. Please read the linked article carefully.
I strongly recommend that you verify this with your airline prior to attempting the flight, otherwise you may be turned back to your point of origin.
