Oh God, that sounds an awful lot like two more Australian systems: the Queensland Health payroll debacle, where a bunch of health workers were paid incorrectly or not at all. Or the National Disability Insurance Scheme debacle, where healthcare providers haven't been paid, resulting in small business owners having to take out huge amounts of personal debt just to pay their employees, and sole traders unable to provide services their clients need to live day to day while still keeping a roof over their own heads. (They're both IBM projects too.)
