Compulsory voting
Compulsory voting is increasingly resented by citizens in some countries such as Brazil, the largest country where compulsory voting is enforced: at the last presidential election in 2014, some 30 million voters, about 21% of registered voters, did not vote, despite the fact that Brazil has some of the most severe penalties enforced against non voters.
Electoral system of Australia
Voting is compulsory at federal elections, by-elections and referendums for those on the electoral roll, as well as for State and Territory elections. Australia enforces compulsory voting. People in this situation are asked to explain their failure to vote. If no satisfactory reason is provided (for example, illness or religious prohibition), a fine of up to $170 is imposed, and failure to pay the fine may result in a court hearing and additional costs. About 5% of enrolled voters fail to vote at most elections. In South Australia, Tasmania and Western Australia voting at local elections is not compulsory. In the other states, local council elections are also compulsory.
