The table below considers national parliament, presidential, and regional elections in Oceanian states and territories, including national parliament by-elections. It includes all regional elections and some local elections where these are held on a national basis or involve a capital city. “National parliament” in bicameral systems refers to the lower house unless specified otherwise.
The tilde (~) indicates that the election will occur in or around that month and no election date has been set yet. If only a month is mentioned, the election will take place in the month, but no date has been set yet. Elections in states marked with the asterisks (*) are not considered free or fair.
