In an Australian first trial, customers can tap a credit or debit Mastercard, or a mobile device linked to a Mastercard, at the Opal Card readers for the Manly to Circular Quay ferry.
The cost of a journey using contactless payment will be the same as an Adult Opal single trip ticket.
Minister for Transport and Infrastructure Andrew Constance said it made sense to trial contactless payments for public transport customers.
“We know that 40 per cent of our passengers on the Circular Quay to Manly ferry are visitors to Sydney, so it makes sense to provide a convenient solution to those who may not have an Opal card,” Mr Constance said.
Other card providers are set to join over the next year.
