Posting history
The Australian government established a High Commission in Port of Spain in May 2004 and appointed its first resident High Commissioner, John Michell. Previously, responsibility for Australian diplomatic representation in Trinidad and Tobago was held in Canada (1974); Jamaica (1975–1994); and Barbados (1994–2004). The decision to move Australian Government representation from Barbados to Trinidad and Tobago was part of a review of Australia's diplomatic network completed in July 2003.
