Can a U.S. Citizen Work in Australia While Visiting?
Generally, a visitor should not assume that a tourist visit provides permission to work.
An ETA allows certain business visitor activities, but that is different from taking up employment in Australia.
If your goal is to work, then you need to explore an Australian visa that provides the appropriate work rights.
This is an important distinction because attending meetings or undertaking permitted business visitor activities is not the same thing as accepting a job and working for an Australian employer.
Can an American Study in Australia as a Visitor?
The rules depend on the type of visa and the length and nature of the study.
Australia’s ETA allows certain study or training activities for up to three months, subject to the visa conditions.
For longer or different types of study, a visitor should investigate the appropriate Australian student visa rather than assuming a visitor authorization will cover the entire period.
