1991 ban on the import of 4 purebreed dogs. X breeds and consignments of semen and embryos were not covered. In 2005 another dog was added to the import ban the presa canario.
Restricted breed legislation first came into effect in South Australia in 1995, New South Wales in 1998, Queensland and Victoria in 2001, Western Australia in 2002 and Tasmania 2010. There have been amendments to these ever since.
