Commuting on Queensland’s Go, Melbourne’s Myki and Sydney’s Opal travel cards could be made made simpler as part of a major public transport shakeup.

Queensland’s $134 million, 10-year-old Go Card ticketing system is set to be eventually replaced by a tap-and-go bank card and smartphone payment service.

In Queensland, the new card and smartphone scheme may be trialled initially on Brisbane's Airtrain airport transport service and then introduced more widely, pending the trial’s success.

It is hoped phasing out Go Cards will streamline payments and allow commuters to travel with one less travel card.

The Go Card currently costs $10 to purchase.

Brisbane commuters take around three million Go Card trips a week. More than 9.2 million cards are currently in circulation.

A $700 million contract for the myki system in Melbourne was signed last year and is now in effect.

Part of that contract meant the contractor had to look at ways to upgrade the system.

"We are always looking for ways to make the public transport system more accessible for Victorians," Public Transport Minister Jacinta Allan said.

"Last year we upgraded all Myki vending machines to feature contactless payment to make it easier and quicker to top up your Myki.

"We are currently looking at a range of options to make it easier for more Victorians to use our public transport system and we will have more to say once we have finalised the best option to help commuters."

Victorian Premier Daniel Andrews said an all-encompassing 'smart card system' would precede a mobile phone system for commuters.

"Getting a smart card system is all about ultimately being able to transition to a smart phone system," Mr Andrews said today.

There are 15,079,598 active Myki cards in Victoria, with 397,980,352 "touch-ons" last year and 386,353,151 "touch-offs".

NSW Transport Minister Andrew Constance today confirmed three more private ferry routes would adopt the tap and go OpalPay system.

Customers will be able to use the service on the Manly-Darling Harbour, Circular Quay-Lane Cove and the Circular Quay-Watsons Bay routes on Sealink and Captain Cook Cruises services.

"Since launching OpalPay in December, it has smashed expectations, with customers completing 100,000 transactions," Mr Constance said.

"We know how popular tap and go payments are and this rollout is about continuing to spread the convenience of Opal to a wider range of transport services, making journeys even easier for our customers."
