GML has provided ongoing heritage advice for the iconic Sydney Opera House since 2005—conserving heritage values while also offering innovative ideas for interpretation.

From 2011–2014, GML assessed the archaeological potential of the site and monitored works during a major upgrade to the forecourt. We also conducted excavations, discovering tangible evidence of the earliest lime production in Sydney.

3D scanning techniques were then used to record archaeological remains and an interpretive film, Revealing Archaeology, was produced.

The 3D recording created efficiencies in the development approval process for the forecourt works, while also developing valuable resources for future researchers. In 2014, the National Trust highly commended the resulting film at its annual Heritage Awards.

In 2015, GML collaborated with Trigger to explore new heritage interpretation opportunities—identifying potential audiences and new thematic directions for engaging self-guided tours, digital technologies and fresh approaches to visitor journeys.
