In January 2004, the Australian Government introduced a new federal heritage regime based around the National Heritage List (NHL). This regime has a significant governance defect; the heritage minister controls the list rather than an independent heritage body, exposing it to political manipulation. This article reviews the NHL listing process and compares it to a ‘best practice’ model. A case study on the Tarkine, a wilderness area in north-west Tasmania, demonstrates how the NHL has been managed and the influence political factors have had on its administration. The case study reveals that the concerns about the politicisation of the NHL are well-founded and that changes ought to be made to ensure the regime fulfils its objectives.
