Changing a job while waiting for PR

Hi guys and gals, fellow applicants :) I've applied for an SC189 visa and still waiting for it of course. I'm thinking of changing my workplace because it seems we still have a long wait ahead of us. My job is not connected to the skill I'm trying to get a visa for. I haven't claimed points for work experience but I did lodge form 80 stating my current workplace. Do you think it's something I should do or should I stay in the current position and wait for the visa. What would you do? Visa application lodged at the end of June.
I asked the same question to my mara agent. she said it wont be a problem and you dont need to submit extra documents. I didn't change my job because of the job offer

That’s totally fine, many people do it.
