You will need to speak to ato to query whether you need to lodge a return. Probably not, given the amount. But thats something only ato can confirm

You need to contact c'link and discuss the employment. If you are invoicing the school, its sounds like you are being deemed a contractor/self employed which means you need to fill in paperwork relating to a business interest, profit and loss statements etc.


Fwiw, for anyone reading - it will not just be taken from your supplements. A debt may be raised, which may include an additional penalty for not reporting within 14 days of the change of circumstance. If you are working, income needs to be reported in the period you earn it, not when it's paid to you. For self employment it is processed differently (you fill in anticipated profit and loss for a period of time).

Get on the phone tomorrow and get it sorted...
