The Bendigo Military Museum is the latest victim in a string of attacks against religious and cultural sites across Bendigo.
The building on Pall Mall has had a liquid splashed on it, resulting in damage to the sandstone exterior.
The hit on the Soldiers Memorial Institute Building, which houses the Bendigo Military Museum, has prompted an investigation by the Victoria Police Force, who have been on-site to gather samples of the unidentified liquid or substance used in the act.
This follows the May 5 attacks on the Golden Dragon Museum and the Great Stupa when two people damaged multiple statues, paintings and imperial dragon Sun Loong with a similar liquid.
Police are investigating whether the incidents are linked.
The vandalism has resulted in damage to the sandstone of the building, particularly noticeable on the exterior walls. The extent of the damage to the Heritage Listed Honour Boards on the front of the building and the plaques on the memorial wall is currently being assessed. It remains unclear whether these important historical artifacts have sustained any irreversible harm.
The Bendigo Military Museum and the Veteran community say they are deeply saddened by this senseless act of vandalism, which disrespects the memory of local servicemen and women who sacrificed for our nation.
