The currency used is Australian dollars, available in A$ 100,50,20,10,and 5. Mastercard and Visa credit cards are accepted which makes it easier to conduct financial transactions, though this may not be the case in outlying islands. The cost of a holiday/visit to Kiribati is higher than most other Pacific countries because nothing is produced on the islands so the cost of food and other items is more.
