The day after the election –always a Sunday in South Australia - every vote counted on election night is counted again under the supervision of the returning officer.
The returning officer also looks closely at all the ballot papers that were placed in the informal pile on election night. Some ballot papers may in fact be formal and can be counted. Some ballot papers that don’t have all the preferences marked on them can be accepted as formal if they match a voting ticket lodged by a candidate.
Any updates to the results after the re-checks have been done are published on the ECSA website and in the media.
