Potentially weird Q about Jobseeker/Workforce

Long one sorry. I'm also bad at TL;DR.

Ok so quick context. Signed up for Jobseeker in April because I was in hospital for a few weeks and I only worked Casually (but essentially Part Time hours). Have exemption for working part-time and usually don't even get a payment because my income is over the threshold. Mostly kept it for the benefits of a HCC since I have a lot of meds.

I've been looking for a new job for awhile on and off since I hate working Casually anyway and recently just got hired full time. None of this was Provided assisted - technically i've never even MET my provider. They called me
once and that was it. I did also email them twice and never received a response. I also received the message saying I can cease working with my Provider now since I work over the hourly threshhold (at the job i'm about to resign from) and will absolutely be over the threshold at my new job. Ao I don't have to report points to Workforce and essentially have no obligations other than reporting to Centrelink.

When it says 'contact Centrelink if your circumstances have changed' does that mean I have to tell them, 'Yep I got a full time job', or can I just continue reporting fortnightly the hours and wages and wait until they cancel my JSK?

I've never had JSK before, i've only ever been on Youth Allowance when I was a uni student a few years back (graduated) and they work so differently haha.
