Planning to migrate to Western Australia

I’m a business graduate who’s planning to migrate. Are these careers a good path to take to be able to migrate to Western Australia?

1. English Teacher

• I’ve seen some posts & comments in this sub that education is a good career path to take when wanting to migrate. I don’t have an education degree but I’m planning to get a TEFL/TESOL certification. Is this sufficient enough?
• Aside from teaching English, what specific path related to education would be a good option?

2. Project Manager/Coordinator

• I’m planning to take a short course online and get a Project Manager certification/license if this is a good career path to take.

Aside from these, would you guys have any recommendations on what other paths to take aside from the medical field to be able to migrate to AUS? Thank you!
