Do I need a transit visa when travelling from UK to New Zealand stopping in Sydney for one hour 30 minutes?
According to the Australian department of immigration, you need a transit visa unless all of the following conditions are met:
- Your stop lasts no longer than 8 hours (ok).
- You remain in the transit area (so not ok if you need to retrieve and check in your luggage in Sydney).
- You must have an accepted passport. Mostly this means you are from Europe, Oceania or North America (but check this page for the exact list of countries).
Otherwise, you must get a transit visa. It's free, but you must apply in advance, after booking your flight and if necessary obtaining a visa for your destination.
You don't need a transit visa for Sydney as you can see here. UK is included in the list of countries that doesn't need it.
Also if you hold a British passport you are included.
Transit without visa arrangements
