This document has been released recently, prepared by the Australian Heritage Council and the Department of the Environment and Energy heritage staff, on the request of the Minister, the Hon Josh Frydenberg MP, who sought advice on the adequacy of existing legal protections for places and monuments that relate to the early interactions between European explorers and settlers and Australia's Indigenous peoples. The report finds that the current legislative and policy framework across the country is adequate, but also makes a number of recommendations to allow Australians to further recognise and promote our shared Indigenous and colonial heritage.
The report can be found at https://www.environment.gov.au/system/files/resources/4474fb91-bd90-4424-b671-9e2ab9c39cca/files/protection-australia-commemorative-places-monuments.pdf

Also, in March 2018, it was announced that this place had been added to the NHL after a review of the earlier Emergency Nomination Listing. It was seen as an iconic part of Melbourne and the place as a whole is a parkland landscape developed and shaped by its historic and on-going function as a rare government domain. The Kings Domain Resting Place within the parklands is also of particular significance because of its association with Australia's national story of the repatriation of Indigenous people's remains.
