First of all: Coming from Australia, no European immigration officer will consider you a particular threat and unless you look or behave suspiciously, chances are close to zero that you will get any question at all at the border.
If you for some reason should be more thoroughly checked, the actual requirement is to have sufficient means to provide for yourself during the intended stay and to leave the Schengen area again. That does not mean that you have to show already booked accomodation or onward transport, but you must strictly speaking be able to show that you have enough money to buy so. If you don't have either a booked accomodation, nor an onward ticket and also currently have problems accessing cash, it might, at least in theory, actually be a problem.
