The Australia Working Holiday visa is valid for one year starting from the day you first enter the country. It is a multi-entry visa meaning you are allowed to leave and re-enter Australia as many times as you like during that year. Yes, that means you can take a vacation to Fiji, Bali or maybe New Zealand during your working holiday! However, keep in mind that while you are outside of Australia your visa is still active. It does not go on hold while you are out of the country and will expire 365 days after you first entered.
