Opal a gem for Public Transport

Opal card and walletLondon has its Oyster, Hong Kong has its Octopus and Sydney will have its Opal.
The Opal ticketing system will be a simple and easy way to access the public transport system across greater Sydney. Customers will be able to load money onto a wallet sized plastic card and use it to pay for their travel.
Opal will give customers more freedom to explore Sydney, the Blue Mountains, the Illawarra, Hunter, Southern Highlands, Central Coast and everywhere in between.
The name Opal has been chosen because it is uniquely Australian, short, and easy to say. 
As well as being the national gemstone, the black opal is the State’s gemstone symbol.
The new name was chosen from a shortlist which also included Beep, Get About, Flexy and Dingo.
Smartcard travel will be available on the Sydney Ferries network first, then the CityRail network and then on government and private bus networks in the greater Sydney area.
The system will use proven technology and is comparable to London's Oyster card. 
However, it is being designed and will be delivered to suit the unique requirements of greater Sydney's transport system and environment.
Early works and site surveys are currently underway to prepare for installation of the new system.
