In August 1924 a letter sent from an Aboriginal man, Tom Lacey, in Sydney to Amy Jacques Garvey - associate editor of The Negro World - reveals new insights on the rise of early Aborginal political activism. Amy Jacques Garvey was the wife of Marcus Garvey, at the time probably similaneously the most revered and despised black man on the planet. Garvey was the leader of the Universal Negro Improvement Association (UNIA) which remains the biggest black movement ever established in the United States. The letter from Lacey was published in Garvey's Negro World under the banner 'Australia sends Greeting to the Fourth International conference'. This article explores the significance and genesis of these international black connections with early Aboriginal political leaders on the Sydney waterfront.
