According to recent reports, Department of Immigration and Border Protection (DIBP) will be uplifting the age from 30 to 35 years for candidates applying for a Working Holiday and Work and Holiday visa to Australia.
At this situation, there has not been any official statement by the Australian government, so the age limit of 30 years is still the same.
Before raising the age limit, there are some key factors which have to be kept in mind; legal requirements, timeframes, and the most important; reciprocity from partner countries for Australian citizens must be in place before the changes in age limit are made. In case, the age limit is raised, only the passport holders with the countries that are in collaboration with Australia regarding the reciprocal agreement will be applicable for the program.
