An study released by the State Government in 2001 showed over 1 in 4 (27.2%) of the machines at train stations did not work, and 11.9% of mobile equipment in buses and trams was non-operational. The State Government renegotiated with ticketing network contract operator "OneLink Transit Systems" to improve the service to commuters. Following these improvements, a 2002 audit showed an increase in availability of machines to 92.1% at train stations, and 98.3% on buses and trams. Usability was also improved, with tram machines able to sell daily tickets. Furthermore, vandalism across the network dropped by 62% between 2001 and 2002.
