ATM commonly dispensed by cash machines
Bars are scaled to face value on a log scale, not to physical size. Colours are the issuer’s own. Converted at mid-market reference rates; what a counter pays is always less.

| $10 | blue | polymer substrate, clear window, microprint |
| $20 | red | polymer substrate, clear window, microprint |

Getting cash
Australian cash machines usually dispense $20 and $50 notes. Australia issued the world's first full series of polymer banknotes, developed jointly by the Reserve Bank and CSIRO. Every banknote the RBA has ever issued remains legal tender, so an old design is still valid, though retailers unfamiliar with it may hesitate, and most commercial banks will redeem it at face value. Pre-decimal notes convert at twice their face value (£1 = $2, £5 = $10, £10 = $20); the sole exception is the 10 shilling note, which converts to $1.
Telling a real note from a fake
Security features are designed to be checked by hand in a few seconds, tilt it, feel it, hold it to the light. These are the features Reserve Bank of Australia publishes for the Australian dollar.
