The Electoral Commission of South Australia says it is investigating suspected voting irregularities in three local council elections, including "suspicious" enrolments and suggestions some ballots have been filled in by people other than those they were sent to.
Returned ballots from the Adelaide, Marion and West Torrens councils have been identified for further scrutiny, and efforts to investigate potential electoral fraud have included handwriting analysis and direct phone calls to voters to check whether they have cast ballots.
