See my other reply re training, employers here in WA generally want a Cert III minimum. There are jobs available but the pay is pretty poor. There are plenty of industries paying better for equally physical work (albeit not in a garden environment) and not requiring certification.
It is not always about the money. After 20 years in tech I'd love to have a job that is more outdoors and less repetitive. I'm even considering homesteading at this point...
