three or six months of specified work in Australia, you may be able to
apply for a second or third Working Holiday Maker visa.
The Australian Government has introduced new measures in response to COVID-19.
Working holiday makers who are employed in critical sectors including
agriculture, health, aged and disability care and childcare will be exempt
from the six month work limitation with one employer.
Working holiday makers employed in critical sectors who haven’t completed the
3 or 6 months of specified work required to apply for a second or third
Working Holiday Maker visa, and are unable to return to their home country can
apply for COVID-19 pandemic Temporary Activity Visa (subclass 408) Australian

Visa condition 8547 — six month work limitation with one employer
Working Holiday Makers can do any kind of work during their stay in Australia,
but this is generally limited to six months’ work with any one employer,
unless the Department has given permission to work with the same employer for
longer than six months.
Working Holiday Makers working in critical sectors, like health, aged care or
agriculture have permission from the Department to work for the same employer
for longer than six months, on the grounds of exceptional, unforeseen
circumstances.
Other situations where Working Holiday Makers have permission from the
Department to work for the same employer for longer than six months, include
where the work is:

in different locations and work in any one location does not exceed six months
in plant and animal cultivation anywhere in Australia
in certain industries in northern Australia only
assisting bushfire recovery efforts.

In any other circumstance, you need to request
permission
to work with the same employer for longer than 6 months.
