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?


You won’t get far with that kind of thing in Australia. We have no land borders with other countries so the “natural” blending of currencies with nearby countries at border cities doesn’t happen. Nobody has a good idea of what a euro or US dollar looks like, and you’ll likely just get told to go get it exchanged for AUD.
