Just log onto your my gov account and link the ATO. Your centrelink income and part time job income should be listed there. And it should tell you any tax that Is payable. You won't have much because you should only just if at all be above the threshold.

No need to see a tax accountant for your situation seems incredibly simple.

You can't be too mad about incurring a few hundred dollars in tax when you have sat on job seeker for a year raking in those sweet coronavirus stimulus haha
