As an aside, back in the early 2000's the NSW Government contracted ERG (a Perth based technology company) to implement a Smart Card system for public transport. ERG had already successfully rolled out Smart Card systems for other local public transport systems worldwide to much success, most notably for the Hong Kong public transport system, the MTR (Octopus Card), in 1997, which is still the largest such deployment to date with tens of millions of transactions daily.
Unfortunately the NSW contract ended in lawsuits back and forth with the NSW Government trying to reclaim the project cost and eventually (arguably) led to ERG's demise. Sad that a successful Australian company, a leader in it's field, able to deploy complicated systems worldwide was (in part) taken down in it's own backyard by a (in comparison) pretty straight forward project.
