GML works extensively with Commonwealth Government authorities and agencies, especially around compliance with the Environmental Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act) and the identification, conservation and protection of heritage values on Commonwealth owned land. GML’s Commonwealth Government heritage work includes strategic heritage management advice, heritage assessment, heritage management planning, and specialist advice on EPBC referrals and national heritage listings.
GML has been appointed to specialist heritage panels including the Defence Environment and Heritage Panel, Department of Finance and the Australian War Memorial. Our Canberra office provides efficient services to Commonwealth agencies.


Thanks again for your efforts with this project. Your expertise and understanding of heritage management on the federally leased airports has been invaluable.

ANU manages an increasingly diverse range of heritage values including natural, historic and Indigenous values on all of its campuses and has found GML’s rigorous and considered approach to heritage conservation and management to be a great asset to many projects. The professionalism and experience of the GML team combined with their knowledge of relevant legislation and best practice methodologies ensure that their advice and outputs are of a high quality.

The wide-ranging expertise of the team also ensures all manner of projects can be adequately resourced in-house which is of benefit to ANU in its procurement practices. GML team members have also demonstrated their strong ability in consulting with a wide variety of stakeholders, including academics, trade staff, facility managers, architects, landscape specialists and approval authorities. ANU Facilities and Services would not hesitate in recommending GML.

GML has undertaken several key pieces of work for the ANU since 2010 including input to the Campus Masterplan, development of the Acton Campus Heritage Study and heritage advice and impact assessment on several key development projects at several ANU campuses including Acton, Mt Stromlo Observatory and Siding Spring Observatory. GML has played a significant role in establishing the current framework for heritage conservation and management at ANU.

I would take this opportunity to thank you and the GML team in undertaking the independent peer review in a professional manner and providing valuable input into the draft EIS (European and Aboriginal Heritage Chapters) that resulted in a quality and robust document. The mutual objectives of all parties were met and I noted the sensitive manner that your team took during the face-to-face briefing sessions—a major contributor to the overall outcomes.

Within this tenuous framework, GML has collated all the previous known documentation related to the heritage of Cockatoo Island, catalogued the whole site, including every remaining building and piece of equipment, and provided Defence with clear policies and priorities for maintenance of the Island.

Keir Malpas, Director, Major Decontamination Projects, Department of Defence

GML has been closely associated with the Memorial as its heritage consultant for a number of years. GML was instrumental in the development of the Memorial’s 2008 Heritage Register and Strategy and 2011 Heritage Management Plan and, since then, has provided detailed heritage advice on all major heritage and site development projects undertaken by the Memorial. GML are rigorous in their approach, provide extremely high quality advice, and have an outstanding ability to communicate effectively with the range of legislative, technical, design, and internal stakeholders involved in all heritage significant projects undertaken by the Memorial. GML is highly capable and well resourced and I recommend them without reservation.

Stewart Mitchell, Head of Buildings and Services 2004–2013, Australian War Memorial
