Can someone please help me work out our rent assistance?

I'm married and my wife and I live together but shes not an Australian citizen. I get ftb A and B And am currently using paid parental leave while going back to work part time.

My wife isn't working at all as shes looking after a 1 month old baby but she gets no other payments.

We pay $580/wk rent and are the only ones living in the house.

We seem to be getting $94.5 per fortnight rent assistance. Does this seem right? If it is that's fine but it just seems a bit low compared to what the full rate is.

Can anyone help explain this?
