Question on Student Visa SC500 Working Restrictions

Hi guys! I am about to graduate from my Bachelor's degree this month and just finished my final semester. My final semester officially ended on 21st November 2025, but my COE Course end Date is not until somewhere in December. Now my question is, do I have to wait until my COE Course end date or can I begin working unlimited hours after 21st November?

TIA for any help you may provide! :)
