One of the functions of the AEC is the maintenance of the
electoral roll, which in some other countries are called electoral registers. In Australia the process of getting onto the electoral roll is called "enrolment". The AEC maintains Australia's federal electoral roll, which is used for federal elections,
by-elections and referendums. Australia has maintained a permanent federal electoral roll since 1908 and, by amendment to the Commonwealth Electoral Act, enrolment has been compulsory for federal elections since 1924. Though each state and territory also has its own electoral commission or office, voters need to register only with the AEC, which shares the registration details with the relevant state electoral bodies. The federal roll also forms the basis of state (except in Victoria and Western Australia, which maintain their own roll) and local electoral rolls. AEC registration covers federal, state and
local election voter enrolment. In Australia and in each state or territory, it is an offence to fail to vote without valid or sufficient reason, at any federal or state election, and may be punishable by a nominal monetary penalty. The amount varies between federal and state jurisdictions. Usually, people are issued with warnings when it is found they have not voted, and are given an opportunity to show cause. Acceptable reasons for not voting may include illness, being overseas on election day, religious belief, being incarcerated, etc. "I forgot" is not considered acceptable. Section 245 of the
Commonwealth Electoral Act provides that if an elector has been asked the reason for failing to vote and declares a religious belief, this statement shall be regarded as conclusive with no further action being taken. Traditionally, voters could not register after the Close of Roll for an election. In 2004, the
Howard government passed
legislation that prevented registration after 8 pm on the day
the writs were issued. This can be up to 10 days after the election has been announced. The legislation was considered controversial by some Australians, who contended it
disenfranchised first-time voters, or those who forgot to update their enrolment. The law was repealed prior to the
2010 federal election, when
advocacy group GetUp! obtained a
High Court ruling that the changes were unconstitutional. 16 and 17 year olds can provisionally enrol but are not able to vote until they turn 18. == List of Australian Electoral Commissioners and predecessors==
