Tap and go: Sydney has the Opal, but how long will we need it?
Sydney Morning Herald, 31 July 2015
For Sydney public transport users, the Opal card was a long wait. But now the smartcard it is here – 15 years after the former government promised its like for the Sydney Olympics, more than 70 per cent of all journeys are now made on an Opal – there's every chance the card could soon be overhauled. In multiple areas – in what we pay for public transport, in how we pay for it, and in the sort of information we give and receive from transport cards – the arrival of the Opal is likely to be a precursor to bigger changes to come.
