The Gay and Lesbian Kingdom of the Coral Sea Islands was a putative micronation established as a symbolic political protest by a group of gay rights activists based in Australia. Declared in June 2004 in response to the introduction of a government bill to the Australian Parliament in May 2004 that codified the heterosexual definition of marriage, the Kingdom was founded on Australia's external overseas territory of the Coral Sea Islands, a group of uninhabited islets east of the Great Barrier Reef. The Kingdom was dissolved on 17 November 2017 following the "Yes" vote in the Australian Marriage Law Postal Survey legalising same-sex marriage.
