The Working Holiday visa (subclass 417) lets eligible young people work and travel in Australia for up to a year at a time. Ireland, the United Kingdom and Canada are all 417 partner countries whose citizens can apply up to and including age 35, rather than the age-30 cap that applies to most nationalities. US passport holders use the parallel 462 stream instead.
You apply online from outside Australia, must hold a clean character record, and need to show access to about A$5,000 in funds to support yourself on arrival. A first 417 visa application costs A$840; second and third 417 applications cost A$1,000 each.
A first 417 grants one year. Irish and Canadian passport holders qualify for a second year through specified regional work, and a third through six months of it. UK passport holders are the exception: applications lodged with a UK passport from 1 July 2024 need no specified work for second and third 417s.
