i wasnt sure where to put this ..maby should have put it in the work section

I might be going back to work...(ARGHHH SCARY LOL)
Mum says the aged care facility which she co-manages need some help in the kitchen, where ill most likely be working alongside the cook.( that is if i do start working there)

The hours would be 7.30am-1.30pm (casual)
so they wouldnt be long shifts and i could do 1 shift or 5 shifts a week if i wanted, and id only be working for a few months if that as their having someone take over the kitchen next year.

my questions
-Would i lose much of my centrelink payments?
-is it worth even going back?( i think my main reason for accepting to work isnt just because of the money but i wouldnt want to be losing too much money either IYKWIM)
