When I was living with DH I was earning $15 per day after childcare and if I took away the FTB Part A that I was getting from the government. I had to supply all nappies food wipes etc as well.

It cost me $10 per day to get to work ($6 for train ticket and $4 for parking at the station).

So I made about $5 per day. Not cost effective at all. And I earned almost a six figure salary as a lawyer.
