2. Is there a ban on donations from foreign interests to candidates?

Commonwealth Electoral Act 1918 s 302D "Gifts of over $1,000 to political entities (broadly, registered political parties, candidates and Senate groups) or political campaigners must not be made by foreign donors. A foreign donor is a person who does not have a connection to Australia, such as a person who is not an Australian citizen or an entity that does not have a significant business presence in Australia"

Foreign donations of more than $1,000 to members of the House of Representatives, Senators, registered political parties, candidates, Senate groups, third parties and associated entities are banned.
