Yes, taxis in Sydney, Australia, do accept cash, although there has been a significant shift toward digital and contactless payments in recent years. Every official Sydney taxi is required to have a functioning EFTPOS terminal to accept credit and debit cards (including Visa, Mastercard, and American Express) as well as mobile payments like Apple Pay and Google Pay. If you choose to pay with a card, be aware that a surcharge of up to 5% is legally permitted and often automatically added to the fare. Cash remains a valid and common payment method, especially for smaller fares, and drivers are required to provide a receipt upon request regardless of how you pay. For those using apps like 13Cabs or GMK, you can often pre-load your payment details to avoid the need for cash or cards at the end of the trip. While cash is accepted, most locals and frequent travelers prefer "tapping" their card for convenience, but having some Australian Dollars on hand is still a reliable backup for any journey across the city.
