INDEPENDENT federal MP Clive Palmer has stepped up calls for electronic voting after revelations one person is suspected of voting 15 times in the 2013 election.

Federal police will look into 128 cases where Australians voted more than once.

“None of this could happen if people were required to present ID,’’ Mr Palmer told reporters in Canberra today.

“To board a flight you need ID ... but not to exercise your democratic rights.’’

Mr Palmer said an electronic system would also fix the issue.

The MP has been critical of the Australian Electoral Commission following a vote recount in the seat of Fairfax, which he won with a final margin of 53 votes.

Labor Senator Kelvin Thomson also expressed concerns about the lack of voter identification at polling places.

“There’s no check during the day that (people) haven’t gone somewhere else,’’ he said.

“Having computers to mark people off the electoral roll would obviously help.’’

Australian Greens MP Adam Bandt said the AEC generally did a good job despite some recent mistakes.

At the high end, the Australian Electoral Commission claims there are numerous voters who voted up to seven times, with one person alleged to have voted nine times, another 12 times and one 15 times.

“We sent inquiry letters to 18,770 electors who had multiple marks recorded beside their names,” AEC acting head Tom Rogers told a Senate estimates hearing on Tuesday.

Replies are still being processed but more than 8200 have been ruled out as “official error”.

Another 1979 people have admitted voting more than once.

“The greater majority of those, over 81 per cent, being elderly, with poor literacy, or with a poor comprehension of the electoral process,” Mr Rogers said.

In some instances, voters received postal votes and were also provided with ballot papers from mobile AEC officers visiting aged care facilities, he added.

“There are 128 electors who have more than two marks recorded beside their names,” Mr Rogers said.

He could provide no reason for the multiple votes, but said the AEC has notified the Australian Federal Police and Department on Public Prosecutions and plans to refer a large number of cases.

“We take it very seriously,” Mr Rogers said.

Liberal senator Dean Smith said such a high number of repeated votes could not be put down to “electoral literacy”.

“That seems to me a very blatant abuse of the process,” he said.

The WA Senate election result has been declared void by the High Court after 1375 votes mysteriously went missing.
