Australians Against Further Immigration

Australians Against Further Immigration (AAFI) was a far-right Australian political party founded by radiologist Rodney Spencer and his wife Robyn, the parents of actor Jesse Spencer. The party described itself as "eco-nationalist", was opposed to mass immigration and aimed for zero net migration.

AAFI stood candidates at both state and federal level, but never won a seat. The party said it was a mainstream organisation, and sought to distance itself from extremist organisations such as the Australian League of Rights and from the Citizens Electoral Council. In 1994, Franca Arena, then a Labor member of the New South Wales Legislative Council, denounced the party in the New South Wales parliament.

In by-elections in Mackellar and Warringah (safe Liberal seats on the Northern Beaches of Sydney) in 1994, Labor MP Graeme Campbell urged electors to vote for Australians Against Further Immigration (AAFI).

The party was deregistered by the Australian Electoral Commission in December 2005, as lacking the minimum 500 members required to be registered as a political party. It contested the 2007 New South Wales state election, but was also deregistered at the state level not long after.
