 Kamco sub-contracted the installation and repair of myki equipment to ERG, in an A$106 million contract.The tender process was the subject of a number of probity concerns in December 2007, with the Victorian Auditor-General requesting police to investigate a leak of tender documents.Draft reports from the Auditor-General's investigation referred to backdated documents and inconsistent treatment of bidders, but independent reports by Pricewaterhouse Coopers and Avanti Consulting in 2005, as well as the Victorian Auditor-General found that the integrity of the tender process had not been compromised.
