The substantive assessment for sites where Aboriginal heritage is present or likely — done properly, with the community at the table.

The cultural values in an ACHAR are spoken for by Aboriginal people, not the archaeologist. COLCO runs the formal consultation process correctly and respectfully — which is both an ethical obligation and the thing that most often delays or derails a report when done poorly. Getting it right the first time protects your timeline.
An ACHAR is only as good as the judgement behind it. With a former regulator and approved Excavation Director leading your report, the significance assessment and methodology are built to the standard Heritage NSW expects.
Working in the ACT instead? ACHARs are NSW-only — the ACT equivalents are a Cultural Heritage Assessment (CHA) and Statement of Heritage Effect (SHE) under the Heritage Act 2004. See ACT heritage assessments.
An ACHAR is the assessment report; an AHIP (Aboriginal Heritage Impact Permit) is the legal permit to harm Aboriginal objects. The ACHAR provides the evidence and justification that supports an AHIP application. You generally need the ACHAR before you can lodge the AHIP.
Because the 2010 consultation process has mandatory minimum timeframes (allow around three months for consultation alone), a full ACHAR commonly takes several months end to end, longer if test excavation is required. Early engagement is the best way to protect your program.
No. Whether sub-surface testing is required depends on the archaeological potential of the landform and what the survey finds. COLCO will only recommend excavation where it is genuinely needed to assess impact.
