Startling figures reveal the millions of dollars that the NSW Government is pocketing from bus and train passengers who don't tap off. It can be as much as $2m a month, with hundreds of thousands of passengers forgetting to record the end of their trip with Opal cards. Jodi McKay, NSW Shadow Minister for Transport says Mike Baird, NSW Premier is depending on the revenue. In the nine months to last June six million journeys weren't tapped off, netting the government more than $16m. The biggest month was March when more than $2m was collected. The opposition fears some passengers have been unable to tap off because of Opal machine errors. The government denies there's a fault with the Opal system and the number of commuters affected is relatively small.
