Budget - Overview

Now that we know how much sunk cost we have, I came up with an overview of how much we can spend.
This is assuming we go to Blue Mountains etc and the tour cost which I estimate it to be around AUD$120.
I still have not factor in Food and Transportation, so what we have left will be even smaller than this.
Additionally, there is still some places which have not been taken in account, like GOR, Philip Island and the days that are still blank. We also have not booked 1 night in GOR.

I'm beginning to worry that we might overspend.
No more 100 oysters :(
