Computer count system
The NSW Electoral Commission uses a computerised system, PRCC, in order to verify and count ballot papers. This system is used for NSW State general elections, local government elections and certain by-elections in order to:
allocate ballot papers to data entry operators for multiple rounds of data entry
verify and reconcile the ballot paper data entry process
distribute preferences to determine the elected representatives.
The PRCC system is audited by independent experts to confirm that it conforms with legislation.
Certifications relevant to the version of PRCC used for various elections, and to confirm the system aligns with recent legislative changes are published here:
