Archaeological excavations are often carried out as a form of mitigation in response to the impacts of a development. They require approval from the relevant regulatory body. The duration and level of staffing for an excavation depends on the extent of the development and the cultural heritage significance of the site. An archaeological excavation could take a week with a few archaeologists, or months with up to 50 workers. The term ‘salvage excavation’ is becoming increasingly common in Australia. This should not be mistaken for ventures similar to ‘treasure hunting’, which sell artefacts for profit. All archaeological excavations in Australia, whether they are termed ‘salvage’ or not, are carried out with government approval and adhere to the strictest archaeological standards and ethics.
