So 16 countries (14 if you don't count Cantons and Oz possessions) have enforced compulsory voting with Oz being the only main stream commonwealth country. It joins the forward thinking luminary democracies of North Korea and most of South America in their pious wisdom.

Thanks for the entertainment.

• Argentina – Introduced in 1912 with the Sáenz Peña Law.^[44] Compulsory for citizens between 18 and 70 years old. Registered voters who abstain from voting without a justification, which are few and closely checked, are fined AR$50. In case of non payment, the person concerned is barred from dealing with public bodies for one year. ^[45] Despite this, absenteeism has tended to increase in recent decades at presidential elections, from a low of 15% in 1983 to a high of 25% in 2015 and to 23.6% in 2019.^[46]
• Australia – Introduced for state elections in Queensland in 1915, excluding Aboriginal and Torres Strait Islander (Indigenous) Australians. Victoria introduced compulsory voting in 1926, New South Wales and Tasmania in 1928, Western Australia in 1936 (excluding Indigenous Australians), and South Australia in 1942. It was introduced for federal elections in 1924 for British subjects aged 21 and over, but was not compulsory for Indigenous Australians^[47] until 1984. The compulsory voting age for federal elections was reduced to 18 in 1974.^[44]
• Belgium – Introduced in 1894.^[48] Every citizen and registered non-Belgian voter, from the age of 18 has to present themselves in their designated polling station on election day (always a Sunday) at federal, provincial and local elections, however casting a legal vote is not compulsory. Legal sanction for those who fail to present themselves are fines from 40 to 80 €, and up to 200 € for reoffenders. Actually, the government has declared that it has other priorities than prosecuting offenders and no one has been prosecuted since 2003. One reason often given is that prosecuting the many thousands of non-voters within the legal time limit would paralyze the already overloaded civil courts. Only the sanctions for absent appointed polling station staff have been enforced by since 2003.^[49][50][51] On the whole, the key Flemish parties on the right are favorable to the abolition of compulsory voting and in October 2019 an agreement was reached to abolish it at provincial and local elections in the Flanders region. In French-speaking Wallonie, the socialist and the other left-wing parties, which form the majority, are adamantly opposed to abolition.^[52]
• Bolivia – The voter is given a card when he/she has voted so that he/she can show proof of participation. The voter would not be able to receive his/her salary from the bank if he/she cannot show the proof of voting during three months after the election.^[53]
• Brazil – Compulsory for literate citizens between 18 and 70 years old, including those who live abroad.^[54][55] Those who do not vote in an election and do not later present an acceptable justification (such as being away from their voting location at the time) are subject to a fine of R$3.51 (about US$0.65 in August 2020). Proof of voting compliance (by having voted, justified the absence or paid the fine) is required for some transactions such as obtaining a passport, admission to a public university, government employment, and loans from a government-owned bank.^[56][57] There is significant opposition to compulsory voting, and despite the enforcement, about 30 million Brazilians (over 20% of registered voters) did not vote at the 2018 election.^[58]
• Ecuador – Introduced in 1936.^[44] Compulsory for citizens between 18 and 65 years old; non-compulsory for citizens aged 16–18, illiterate people, and those older than 65.
• Liechtenstein – The Act on the Exercise of Political Rights in National Affairs (1973) states that "Participation in elections and votes is a compulsory civic duty."^[59][16]
• Luxembourg – Compulsory for Luxembourg citizens aged between 18 and 75 who live in Luxembourg; not compulsory for Luxembourg citizens who are over 75 or live abroad. Foreign citizens (in local and European elections only) may register to vote once they have lived in Luxembourg for 5 years. This is a free choice, not a requirement; however, once an eligible foreign citizen has registered to vote, then voting is compulsory for them.^[60]
• Nauru – Introduced in 1965 when it was still an Australian possession. ^[44]
• North Korea – Everyone over age 17 is required to vote. However, only one candidate appears on the ballot. Voting is designed to track who is and isn't in the country. Dissenting votes are possible but lead to repercussions for voters.^[61]
• Peru – Introduced in 1933.^[44] Compulsory for citizens between 18 and 70 years old.^[62]
• Pitcairn Islands – All permanent residents over 18 years of age are required to vote.^[63] Those who do not vote, without a valid excuse, are subject to a fine up to NZ$25.^[64][65]
• Samoa – Samoa adopted compulsory voting in 2018.^[66] It will be implemented for the first time in the 2021 general election.
• Singapore – Compulsory for citizens above 21 years old as of the date of the last electoral roll revision. For example, the 2015 election has the cut-off date on 1 July 2015. However, amidst the global COVID-19 pandemic in 2020, it is not compulsory for quarantined voters and voters affected by stay-in orders to vote.^[67] Failure to vote will result in the removal of one’s name from the electoral roll.

• Swiss canton of Schaffhausen – Compulsory voting never existed on the national level in Switzerland. It was introduced by several cantons, starting in the late 19th century, but by 1974 it was repealed everywhere, except in Schauffhausen.^[44]
• Uruguay – Introduced in 1934, but not put into practice until 1970.^[44]
