Direct proof of use
The Bushmaster PMV is directly documented in the 2003 Iraq War through Australian parliamentary reporting and Australian War Memorial collection material. An April 2005 deployment report said up to ten Bushmasters would deploy to southern Iraq with the Al Muthanna Task Group to provide additional transport protection for Australian Defence Force personnel.
During an October 2005 parliamentary delegation visit, the Al Muthanna Task Group briefed the delegation on its ASLAV and Bushmaster vehicles at Camp Smitty, southern Iraq. The same report says delegates were transported in Australian Bushmasters from Tallil to Camp Smitty and later travelled by Bushmaster to As Samawah under Combat Team Eagle escort.

Timeline
Australia expanded its Iraq commitment in 2005 with the Al Muthanna Task Group, a force assigned to security operations in Al Muthanna province and training support for Iraqi security forces. Bushmasters were prepared for deployment that April and were documented with the task group in southern Iraq by October 2005.
By 2008, Bushmasters remained part of Australia's Iraq vehicle fleet. The Australian War Memorial records a Bushmaster PMV with a remote weapon station at Tallil, Iraq, photographed between 29 April and 13 May 2008 during the early withdrawal of Overwatch Battle Group (West) before combat operations ceased in June 2008.

Operational role
The sourced Iraq record places the Bushmaster on the United States and coalition side of the war through Australian Army formations serving under Operation Catalyst. Its documented operators in this record are Australian forces with the Al Muthanna Task Group and later Overwatch Battle Group (West), not Iraqi insurgent or Iraqi government forces.
In Iraq, the Bushmaster's documented role was protected mobility rather than heavy armored combat. Parliament's delegation report describes it as an armored truck for carrying support and logistic personnel in a protected, air-conditioned cabin, and records that it was used for movement between Tallil, Camp Smitty, and As Samawah.
The vehicle's use matched the threat environment that made protected troop movement central to coalition operations. Australian Army and ASPI material describe the Bushmaster's V-shaped hull and blast-resistant design as intended to protect occupants from landmines and explosive devices, while the direct Iraq sources show those vehicles assigned to transport-protection tasks in southern Iraq.
