Will Centrelink know about my OF?

Morning guys

I'm on the full rate of Centrelink parenting payment + 4x Family Tax Benefits.

I also make $1.2k a week working 2 hours as an OF content creator.

I choose to keep Centrelink because the cost of living is insane. It's too hard to afford iPads for the kids and McDonalds for dinner each night otherwise.

Will Centrelink find out about my electronic income?
