It's not that hard to get into healthcare and start work, thing is, do you have the stomach to stay in the work, get abused and clean up **** daily for your job. Australia gets immigrants for hospital work, mostly because locals don't want to do it. The real issue is not immigrants but casualised workforce that are forced to work across multiple sites as they can't get enough livable hours on one facility, which from a healthcare point of view is just inviting the spread of disease like Covid.
