Yes you can apply for jobs in Australia as long as your Visa has no working restrictions.
There are a number of visas that allow you to work, but most have restrictions about the kind of work you can do. For example:
- If you have a tourist visa, you CAN’T WORK at all.
- If you have a student visa and work permit, you can only work up to 20 hours per week while you are studying.
- If you have a working holiday visa, you are not allowed to work for any one employer for more than 6 months.
Each type of visa has special conditions.
