Hospital jobs with little training? Are there any certifications that take less than 3 months to get that would help me get a job in a hospital? 

I am currently in Australia with my partner who is a graduate student. I used to work in healthcare in the United States but my certifications did not transfer here. I can only study for up to 3 months on my visa but I do have unlimited work rights so I can work full time. I am not that picky on what type of work- but I would really like to get back to working in a healthcare setting.
