GML works with State and Territory Government authorities and agencies across Australia, helping them identify, conserve and manage heritage assets in accordance with state legislative requirements. Our work for the states and territories includes strategic heritage advice, heritage assessments, conservation planning, policies and reviews, heritage and conservation registers, heritage masterplanning and heritage training.


I value working with GML as they have the ability to work with a variety of stakeholders to achieve consensus about heritage conservation outcomes. GML communicates in a manner which is fit for the task, concise and highly effective.

I also wanted to say congratulations on what I consider to be an exemplar plan, certainly the best that I have been involved with at my time at NPWS. I also wanted to say what a pleasure it was to work with you and your consultant team on this project, and sincerely thank you for what I know was a lot of extra hard work and effort on your part. I must say that we really have appreciated all of the extra touches, from the scanned set of photographs on CD that we received early on in the piece, to the extra PDF copies at the end. I really felt that you and your team gave it 110 per cent and I really appreciate it.
