Some ambulance officers will be given years to pay back tens of thousands of dollars they were overpayed due to an administrative error, the government says.
The error was caused during the reconciling of a manual paper-based leave system and a new electronic system introduced in 2009-10.
The government says 133 of the ACT Ambulance Service's 250 employees were affected by the error.
Thirteen staff owe $10,000 or more, seven between $5000 and $10,000, 21 between $1000 and $5000, 13 between $500 and $1000, and 16 owe $500 or less.
Emergency Services Minister Simon Corbell said the government would work with the employees to find the most feasible and flexible ways to repay. ''In many instances, where the liability is not disputed, staff will be able to make this a cashless transaction; they'll be able to utilise existing leave entitlements to pay down any debt that is owed,'' he said.
Several ambulance officers have disputed that they owe the ambulance service money.
Mr Corbell said the ACT Ambulance Service would work with those officers to address their concerns.
