Harold Freedman’s expansive mural depicting the history of Australian military aviation has been restored and returned to public display at the Australian War Memorial after more than two decades out of sight. Originally commissioned in 1968, the 256-square-metre artwork charts the nation’s aviation heritage, featuring aircraft ranging from early hot air balloons to supersonic spy planes.

The mural, once dubbed the “Sistine Chapel of military aviation” by Australian War Memorial director Matt Anderson, was a formative experience for many visitors during the 1970s and 1980s. Anderson, recalling visits with his father, described how the mural sparked his early interest in aircraft by inviting viewers to identify and learn about the depicted planes. He said the work continues to reveal new details with each viewing and remains a source of inspiration. Posters of the mural adorned his bedroom wall through his youth and now hang in his office.

Curator Garth O’Connell, another longtime admirer, credits the mural for nurturing his passion for military aviation. He recounted memorising the images as a child and how studying the artwork helped fuel his 26-year career at the Memorial.

The mural was removed from public view in 1999 and was only rediscovered during renovations for the Memorial’s Anzac Hall. Conservators undertook an extensive restoration process using delicate tools such as fine brushes, cotton pads, and cue tips to address flaking, blemishes, and discoloration. Anderson described the project as one of the most precise and painstaking conservation efforts undertaken by the Memorial’s team.

Freedman’s son, David, expressed pride and satisfaction at seeing his father’s work revived. He recalled a conversation with his father, who doubted his lasting legacy but diligently pursued his craft. David Freedman hopes the mural will one day be expanded to incorporate more recent aircraft, encouraging future generations of aviation enthusiasts and artists to build on the original.

The restored mural is now accessible once again, serving as both a historical record and an artistic tribute to Australia’s aviation achievements.
