Archaeological Excavations

Where Science and Cultural Values Shape Investigations

Archaeological excavations are usually undertaken to address clearly defined scientific questions about the presence, nature and significance of cultural heritage within an activity area.

These investigations form a critical evidence base, informing significance assessments, impact evaluation, and decision‑making under relevant heritage legislation.

Salvage excavation is undertaken only where impacts to archaeological sites or deposits cannot be avoided or mitigated through design or management measures. As the final stage in the cultural heritage assessment process, salvage is conducted once the scientific and cultural values of a place have been established and all statutory approvals and management conditions are in place. Salvage programs are therefore tightly controlled, purpose‑driven, and carried out in accordance with strict regulatory and stakeholder requirements.

Because salvage excavation represents the last opportunity to recover scientific information from an impacted site, it demands the highest level of archaeological expertise, methodological control and operational care. ACHM maintains a full suite of purpose‑built equipment capable of supporting salvage excavations of any scale or complexity, including custom‑designed mechanical sieves engineered to ensure both recovery efficiency and operator safety.

ACHM’s archaeological team comprises highly experienced practitioners with extensive expertise in test and salvage excavations across complex regulatory environments. Our work is grounded in scientific rigor, defensible methodology, and a clear understanding of the responsibilities that come with undertaking salvage as the final stage of cultural heritage investigation.

Frequently Asked Questions

What is archaeological excavation and when is it required for a development project in Australia?

Archaeological excavation is a systematic investigation to determine the presence, nature and significance of sub-surface cultural heritage within an activity area. It may be required when a development, including infrastructure, mining or energy projects, may impact Aboriginal cultural heritage sites that cannot be avoided. It may form a part of the cultural heritage assessment and approvals process under relevant state and territory legislation.

A test excavation investigates whether cultural heritage is present within a proposed activity area and informs significance assessments. Salvage excavation is undertaken usually as the final step, after all avoidance options have been exhausted and statutory approvals are in place. Salvage is one of the final stages of the cultural heritage assessment process and usually represents the last opportunity to recover scientific information from an impacted site.

Archaeological salvage uses three primary methods: surface salvage (artefact collection from the ground surface), manual excavation (hand-dug salvage pits in areas of known cultural deposits) and mechanical excavation (using plant and equipment for large-scale programs). The method is determined by site conditions, approval conditions and Traditional Owner requirements. Programs are tailored to the size and nature of each site.

Duration varies based on the size and complexity of the activity area, the nature of identified cultural heritage and the methods specified in the relevant approvalsor agreed salvage program. Small targeted programs may be completed within days; large-scale salvage programs for major infrastructure or mining projects can run for several weeks or months. A scoped program with clear timelines should be established before works commence.

Artefacts recovered during archaeological excavation are analysed, catalogued and managed in accordance with CHMP conditions and state or territory heritage legislation. Outcomes are determined in consultation with the relevant Registered Aboriginal Party or Traditional Owner group, and typically include reburial on Country, transfer of custody to the relevant Aboriginal Land Council, or curation in an approved facility.

Look for hihgly qualified and experienced professional archaeologists with a track record across complex projects, established Traditional Owner relationships and demonstrated understanding of your project jurisdiction’s regulatory framework. ISO certifications (9001, 14001 and 45001) indicate quality, environmental and safety management standards. Relevant experience in your sector, resources, infrastructure or urban development, is equally important.

An archaeological assessment is the first stage of the cultural heritage investigation process, establishing whether heritage is likely present and what further investigation is needed. If significant sites or deposits are identified that cannot be avoided, test and salvage excavation programs may follow. The excavation program builds on assessment findings to inform significance determinations, statutory approvals and cultural heritage management obligations.

Archaeological site monitoring and targeted excavation can sometimes be integrated into construction programs where careful planning and unexpected finds protocols are in place. However, salvage excavation is usually completed before earthworks commence in affected areas, as it is the final opportunity to recover information from impacted sites. Early engagement with a cultural heritage consultant is essential to avoid programme delays.

A Cultural Heritage Management Plan (CHMP) is the primary statutory approval mechanism for managing Aboriginal cultural heritage impacts in Victoria. Once approved, it sets out management conditions for the activity area, which may include mandatory salvage excavation of identified Aboriginal places before works begin. Proponents are legally responsible for meeting all CHMP conditions prior to construction commencement.
