A record 54 political parties are registered to contest the federal election - a massive jump from the 25 in 2010.
They run, alphabetically, from the Animal Justice Party to the Wikileaks Party.
An Australian Electoral Commission (AEC) spokesman says the list is now frozen.
Being registered entitles candidates to run, in the lower house or Senate, under a party banner.
Among the parties that weren't around in 2010 are the Bank Reform Party, the Bullet Train for Australia, the Coke in the Bubblers Party, the Pirate Party, the Outdoor Recreation Party (Stop the Greens), the Smokers' Rights Party and the Stop CSG Party.
An AEC source speculated that one reason for the big rise in minor party activity was former prime minister Julia Gillard's announcement of an election date so far in advance.
This tended to galvanise interest groups into organising themselves into parties.
