New Australia-UK 3 year working holiday visa.
Currently, UK citizens between the ages of 18 and 30 are eligible for the Working Holiday visa (Subclass 417), which allows you to work and travel in Australia for up to two years.
The UK-Australia trade agreement currently in progress may allow a three year term, for both Australians to the UK, and UK citizens to Australia.
Farm work will not be compulsory under the proposed new rules.
