i dont think that you actually get the "option".

I also thought you could choose but then when i actually went on leave that wasnt the case... If you are returning to work after your leave you get paid it by your employer and they receive the money from centrelink as a reimbursement.. but if you ARENT returning to work then i think that is why you get paid directly from Centrelink..

Atleast that is how i interpreted it....
