Extent Heritage

What Extent Heritage does

Extent Heritage is a privately held Australian heritage and archaeology consulting firm founded in 1998 and headquartered in Pyrmont, New South Wales. The firm delivers professional services spanning heritage advisory, archaeological surveys and excavation, built heritage and adaptive reuse, conservation planning, significance and impact assessments, heritage approvals, archival recording, interpretation, cultural mapping, historical research, and stakeholder engagement. Its client base is dominated by federal, state, and local government agencies alongside private property developers and infrastructure operators, with engagement models built around project-based consulting contracts.

The firm operates across five Australian offices (Sydney, Melbourne, Brisbane, Hobart, Perth) and has extended its service footprint into the Asia-Pacific region (Papua New Guinea) and Europe (Ireland, Norfolk Island). Its technical stack combines advanced GIS and spatial analysis (with over 22 years of internal capability including PhD-level research in convict-period history), 3D modelling and photogrammetry, and digital heritage management systems. Two proprietary product offerings sit alongside the consulting practice: the 'Mini-Museum' — a portable containerised museum (6m x 2.4m x 2.4m) for on-site community engagement — and Digital and Interactive Heritage Management Plans, which are digitised heritage management documents accessible via tablets and mobile phones. The firm is described as owned and managed by heritage professionals and holds ISO accreditation.

Revenue mechanics are driven by project-based professional services fees for heritage consulting engagements. The go-to-market is sales-led, relying on direct engagement with government procurement processes and private developer relationships, supplemented by content marketing through the company's website (project galleries, case studies, and thought-leadership articles) and selective participation in industry events. No publicly disclosed pricing, revenue figures, funding rounds, or ownership details are available.
