Need cash when I land, best place in Vanuatu? Airport or places in the city?
The airport exchange is a scam. I went there once and got a horrible rate. The best option is to get cash from an ATM. The ATMs from banks like BRED Bank are a safe and reliable option. You won't need to exchange your money at all if you have Australian dollars, as they are widely accepted. Otherwise, use an ATM for cash, as the exchange rate will be much better than any exchange counter.
The currency on the islands is the Vatu, and while some places accept Australian dollars, it's best to have local currency. My advice is to get a little cash at the airport just to get to your hotel, and then use a bank ATM for the rest. The ATMs from banks like NBV are reliable and give a good rate. The airport exchange rates are just terrible. It's not worth it, and you'll lose a lot of money.
The airport exchange is a terrible deal. Your best bet is to use an ATM from a bank in the city. You'll find a few ATMs at the airport, but they can be unreliable and have high fees. My advice is to get a little bit of money just to get to your hotel and then find a bank. The ATMs from ANZ in Port Vila are generally very reliable and will give you a good rate.
Don't even bother with the airport exchange counter. It's a complete rip-off. The best way to get cash is from an ATM in the city of Port Vila. The ATMs from major banks like ANZ or National Bank of Vanuatu (NBV) are generally reliable. You'll get a much better exchange rate there than you would from any currency exchange counter. You might want to grab a little cash from the airport just for a taxi, but do a big withdrawal at a proper bank.
