I’ve heard about a movement about keeping cash alive. However, am I allowed to exchange or keep “foreign” cash in Australia despite it being worth more? For example, I hoard cash via the following currencies: USD, BBD, OMR, KWD, PLN, GBP, EUR & AED to name a few and most are higher value than Australian Dollar.
I mean, will stores (in touristy parts of Sydney) accept the following in cash (mentioned above) directly for transactions. Like for instance: this item costs A$50 but gave them a 200€ (A$330) bill as payment, will they take that at face value due to that being worth more despite it being the second most traded currency globally?


Not likely, you may be able to slip a NZ coin or something in a stack but of you try to hand a euro note over the staff will say no because their terminals won’t know how to handle the currency conversion and will make end of day a pain as they now have a euro note.
