Am I qualified enough to become a construction/project manager?

I’m a qualified carpenter, qualified building designer (adv. dip.) currently working drawing residential house plans. I handle most aspects of projects including town planning and building permits. But the pay (just under $70kAUD) isn’t enough to keep me afloat with the cost of everything going up. Could I get a job as a project manager with my current skills or would I need to go back to school? I see jobs on seek for project managers offering 100k
