 There are almost no limits to what employment a working holiday maker can undertake, and although traditionally most of the jobs have been in hospitality or harvest work, many work in finance, education, health care and other industries.Working holiday visa holders are generally not covered by the Australian Medicare health insurance scheme, but they may have limited access because of a reciprocal agreement between Medicare and their home country.The visa allows a young visitor to stay in Australia for up to 12 months from the date of first entry to Australia, regardless of whether the visitor spends the whole time in Australia.
