Sir John Monash Centre, Military museum in Villers-Bretonneux, France.

The Sir John Monash Centre is a 1,000-square-metre museum set behind the Villers-Bretonneux Australian National Memorial, built partly underground with a turf roof so it stays subordinate to the monument. Its entrance pavilion has dark glass panels and a thin dark roof edge, with a white rectangular block to the right; a square grey concrete and stone tower with an open arched belfry section rises behind it, above a paved stone plaza. In the foyer hangs Morning Star, a tapestry by Lyndell Brown and Charles Green made by the Australian Tapestry Workshop.

An Australian visitor centre on the Western Front was first proposed at Le Hamel in 1998, then shelved until 2006. Cox Architecture won the international competition, and Prime Minister Tony Abbott unveiled the design on 26 April 2015. The centre opened to visitors on 16 April 2018 and was officially inaugurated by Malcolm Turnbull on 24 April 2018, with French Prime Minister Édouard Philippe present.

In the foyer hangs Morning Star, a tapestry designed by Australian war artists Lyndell Brown and Charles Green and woven by the Australian Tapestry Workshop. Visitors can load the SJMC App on their own mobile device and use it as a virtual guide through the cemetery, the memorial and the centre.

Visitors should download a dedicated mobile application and bring personal earphones to access the digital content available in several languages. The underground location means entry requires using a specific access point, and visitors should plan time to orient themselves on the site.

The centre's 1,000 square metres are built partly underground with a turf roof, so from the memorial only the low pavilion and a concrete tower show. Architect Joe Agius called it "almost an anti-building", connected to the monument in an abstract, geometric way. The A$100 million cost, met by the Australian Government, was queried by a parliamentary public works inquiry in June 2015.
