So I'm starting work on the 30th of Jan YAYAYAY, I'm so very excited!

I know I need to tell centerlink, but I am wondering when would be the best time, I don't want to tell them too soon, because I can not afford any of my pays to be cut before I start work, or I'd head down debtville very fast... I won't be getting paid until the 8th of Feb from work...

So when should I tell them, from the 8th of Feb? Or before I start? Ekkkkkkk
