Perimeter fencing, erosion control measures and tree protection are now in place at the Australian War Memorial as public consultation about the next steps in the site's planned redevelopment end on Tuesday.
Once the consultation deadline closes, the National Capital Authority will assess the memorial's so-called "early works" - an extension of the underground carpark adjacent to Poppy's Cafe - while considering the public input.
Redevelopment of the memorial's heritage site has attracted significant and robust debate although funding for the major project received bipartisan support when it went before Parliament in 2018.
There was alarm among local residents when perimeter fencing at the site was erected two weeks ago however, the authority confirmed that this activity was "temporary and no stakeholders . . . impacted".
"The NCA will prepare a consultation report that will be published on its website once a decision has been made about the application," the authority's chief executive, Sally Barnes, advised.
The memorial has had $498 million in federal funding approved for a future large-scale redevelopment of the heritage site.
The memorial's director, Dr Brendon Nelson, says that the memorial in its current state was not able to adequately tell the stories of Australian personnel who have served overseas in the past two decades.
Prior to the major redevelopment is the early works program in which trees will be removed from the eastern side of the site and excavation begin to build an underground carpark for 123 extra vehicles.
The memorial says in its planning submission that the 63 trees to be removed will be replaced "once the temporary car park is re-instated".
The car park will be in place for around five years and its structure has been engineered so as to support a 1.5 metre soil depth for future tree plantings.
The car park will be for both visitors and construction staff working on the much larger second phase of the project, the full scope and details of which are not yet disclosed but are tentatively planned to start after Anzac Day 2021.
