Conflict of interest was denied by Public Transport Minister Lynne Kosky. A pilot program was due to begin in early 2007, but was delayed by approximately a year. In the meantime, more than 20,000 pieces of equipment had been installed, with civil engineering works continuing. In February 2008, Public Transport Minister Kosky announced that the full roll-out of the system would not begin until the end of the year. By March the same year, the minister said that the system would not be operational until 2010. In April 2008, TTA announced that it had stopped making service payments to the Kamco consortium after April 2007, because the project had not been delivered on schedule. The first field trial of Myki was held on the Geelong bus network in late 2007. The trial identified problems with 'front office' computer software. In May 2008 Kamco conducted 'Regional Bus Pilot 1' in Geelong, after which it announced that 90% of tests had been passed. According to Kamco's report, Regional Bus Pilot 1 showed that: "Essential onbus activities such as scan on and scan off, top up Myki, purchase of short-term tickets using cash or Myki money, driver log on / off, route and shift selection and GPS connectivity and accuracy performed well. Back office processes and operational procedures such as end-to-end data transaction flows, generation of reports, training, communications, installation and commissioning were generally good. The operator (McHarry's Buslines) was pleased with the NTS training, performance and ease of use of the Myki solution." Further field tests across other transport modes were planned during the second half of 2008, including an additional test on regional buses. In August 2008, testing began on the Melbourne suburban train and tram networks. The train tests involved Kamco staff at East Camberwell, Canterbury, Chatham and Mont Albert stations. On trams, special services on route 86, not open to normal fare-paying passengers, were used. These tests were all single mode, with multi-modal trips to be tried at a later date. On 12 December 2008, Myki went on sale to the general public on four bus routes in Geelong, and on 2 March 2009 all bus routes in the Geelong and Bellarine Peninsula area were completely switched to Myki. In April 2009, all bus services in Ballarat, Bendigo and Seymour were converted to Myki. In May 2009 all bus services in the Latrobe Valley towns of Moe, Morwell, Traralgon and Warragul were operating with Myki equipment, making it the last regional bus system to be converted.
